Getting Ready for Summer: 7 Central Air Conditioner Maintenance Tips

The dog days of summer will be upon us before we know it. It feels good to have sunshine and warmth in the air. It also feels good to go inside and cool off in your nice air-conditioned house.

So, there's nothing quite so frustrating as turning on the air on the first hot day only to find it won't turn on. Or it won't blow cold air.

Of course, then you're in line with others who want service right away to get their air working. Avoid the hassles by getting your central air conditioner maintenance taken care of before it's a problem.

Read on to learn about some things you can do or have done by a professional to make sure your air conditioner is ready for summer.

1. Air Conditioner Filters

One of the simplest tasks you can do, and you can do this yourself, is to clean or replace the air conditioner filters.

These filters are found inside the house. They can be found in the furnace or air handler cabinet of your furnace. Sometimes you will find them near the air inlet part of the furnace.

The purpose of these filters, like any filter, is to trap dirt and air particles. Yet, when these get too full of dust and dirt particles, the air can't move through them.

As a result, you don't get good airflow and your house doesn't cool down the way you want it to.

2. Check the Condenser Coils

Just the name condenser coils sound remarkably complicated. This isn't though.

First, you need to make sure, and this is important, that you have turned off the power to your air conditioner unit.

Then go to the outdoor metal box that is part of your air conditioning system. You will see the fan blades at the top of the unit.

These fan blades move air around the interior condenser coils when your unit is running. During the winter, debris can get inside the unit and clog up the condenser coils.

Remove the lid of your unit and the sides. This often can be done by loosening a few screws.

Then you can use a soft hand brush or vacuum brush to clean the coils. These coils look like fins and are surprisingly fragile. You want to be careful not to bend them while cleaning.

Removing the dirt and debris allows better airflow and a more efficient air conditioner hunt.

3. Debris Around the Condenser

Once you are finished cleaning the coils, you want to remove any debris found inside the condenser. Often leaves and dirt from winter gather inside there.

Use your hand or a vacuum to scoop out the debris. If there is a drain (many units have one) you want to clear out the drain at the bottom of the condenser.

Then you can use a rag to wipe down the fan blades. Check the bolts that hold the fan blades. You want to be sure nothing is loose that would throw off how the fan operates.

4. Remove Outdoor Obstructions

While many people want to do outdoor plantings around the outdoor part of their air conditioner, really this is not a good idea. You want there to be open space and good airflow around the outdoor part of your air conditioning unit.

You want to remove any leaves or weeds that might prevent good airflow around the exterior of the unit.

It's smart to keep anything growing several feet from your air conditioning unit.

5. Check the Coolant Lines

The coolant lines run from your outdoor part of the unit into your house. They run from the air handler inside to the condenser outside.

These coolant lines are typically wrapped in foam insulation. This prevents the coolant lines from losing unnecessary energy.

Sometimes outdoor critters will chew on the foam insulation and it gets frayed away. You want those lines protected for maximum efficiency.

You can replace this with new foam insulation by wrapping the coolant lines and taping them with the insulation tape. These are supplies you can pick up at your local home improvement store.

6. Check for Air Flow Leaks

If it appears your air conditioner is running fine and yet your house isn't cooling the right way, you might have a leak. Leaks in ductwork mean the cool air escapes before it arrives at the rooms in your house.

Check your visible ductwork for loose spots. You can even turn on your system and feel your ducts to see if you feel airflow.

A professional HVAC specialist can also do an inspection of your ductwork to check this.

7. Thermostat

This is a great time to upgrade your thermostat to a programmable thermostat. If your thermostat isn't working, it won't tell your air conditioner to turn on or turn off.

This can be a real drain on your energy bills.

Imagine how nice it will be to come home from work and have your smart thermostat working to have your house cooled off and ready for you.  Some programmable thermostats even allow users to control them from an app on their phone.

ac maintenance

Is Spring a Good Time of the Year to Perform AC Maintenance?

Did you know that the HVAC systems market was priced at $130.5 billion in 2019? Heating, ventilation, and air conditioning are vital when we are in our house for all hours of the day.

We are all stuck inside together, and the temperature of our homes is essential, this spring add ac maintenance to your list of cleaning and reorganizing. Keep reading, and we will guide you through why spring is the season to check in on your air conditioning.

Spring Routine

This spring, we may not be able to leave our homes often, which is why it's more important to make sure your home is clean, comfy, and at the right temperature for you and your family. Spring cleaning is an activity you can involve the whole family during this time indoors.

You want to make sure that you're preparing for warmer months with your air conditioner. We are here to help with our air conditioning check-in services.

Not only is this important for the quality of air and temperature, but having an air conditioner service come in the spring can prevent any summer meltdowns and unexpected expenses.

Why You Should Get AC Maintenance

Every spring, you should get your air conditioner looked at to make sure everything is working. The spring is a time for routine cleaning and getting everything on track before the summer. Your AC maintenance should be on your to-do list along with other spring cleaning chores.

However, this spring, it's even more essential because we are all spending a lot of time in the house, in some cases crammed with our families, roommates, pets, or significant others.

We are going to walk through the benefits of getting your air conditioner checked out this spring:

1. Decrease Monthly Cost

If there are parts of your air conditioner that are dirty or broken, it won't run as efficiently. If your air conditioner is working harder to cool your house, this will result in higher energy bills and monthly costs.

For example, if your AC has dirty coils, it will not be able to get rid of heat easily or quickly, making it work harder to get to the set temperature.

Right now, energy bills are up from having your lights on all day, to using your computer when you work at home or cooking more because everyone is in their house most of the hours of the day. If you can reduce your bill in any way moving forward, it's essential to take preventative action now.

If you invest in getting ac maintenance now, you will save money in the long run, and your monthly costs won't be affected. Spring is so essential because it's before the warmer months of summer, so you're taking preventative action against any issues.

2. Schedule Around You

We are at our busiest during the summer and winter months, with last-minute appointments that come up if a heater breaks in the dead of winter or an air conditioner goes out on a 90 degree summer day. Everyone is using their HVAC systems every day during these seasons.

We have more availability in the spring and can work around your schedule to find a day and time that fits into your day.

Right now, with everyone home, we want to make sure we don't disrupt anyone's workday or come during important meetings.

The future is unknown, and we want to make sure you secure a spot that works in your schedule your appointment today for this spring because we will e able to provide more flexible options.

3. Reduce Risks

If you schedule AC maintenance for the spring, you reduce the risk that your air conditioner will shut down or have issues in the summer. The summer is primetime for AC breakdowns.

The common AC maintenance checklist includes checking for clogs, lubricating all moving parts to make sure nothing is stuck, looking for loose electrical and tightening those, double-check the blower, and other routine checks.

We look to make sure every piece of the puzzle fits so that you're able to be in your home comfortably during the summer months.

4. Air Quality

When your AC has been running for an entire summer, dust and debris builds up and is released the next time you use your system. The allergens can create poor air quality with the excess dust and debris circulating through your house. The dust can cause allergies and a general uncomfortable feeling in your home.

We will check to make sure that nothing is clogged and that there isn't dust and debris in the blower. Removing these allergens will help increase your indoor air quality and reduce the allergy issues making your family comfortable.

5. Lifespan of Air Conditioner

The regular maintenance on your air conditioner can help upkeep the AC and will make it last longer. We can also typically estimate how much more life your older air conditioner has, so it's less of an unexpected expense when the time comes for you to get a new one, and you can prepare for it.

General maintenance and upkeep on your air conditioner is something you should make routine every spring. This spring is almost more important because we all want to be comfortable in our homes and not have to worry about an AC breakdown when summer starts.

7 Warning Signs That Your HVAC System Is Failing

Summer will be here before you know it, and, in Texas, the heat is no joke! With average summer highs running between 86 and 98 degrees, we really rely on our HVAC system to keep us cool. If your system fails, you'll be uncomfortable at best and could face health risks in the worst-case scenario.

This is one of the many reasons why Houston heating maintenance is so important. Keeping up with your HVAC system’s needs and knowing the warning signs that your system is failing will help you avoid finding yourself sweltering in the summer. Here are seven of the most concerning issues you need to watch out for.

1. Indoor Humidity

Part of the way your HVAC system keeps your home comfortable is by removing humidity from the air. This is collected by the system and expelled as water.

Whether it’s the middle of summer or early winter, if your home feels sticky or stuffy, then this is a good sign that you need to have your system looked at.

2. Strange Smells

A strange smell, particularly if it’s lingering, is a sign that you could have an issue with your HVAC system. This could take the form of a burning smell or it may smell moldy, musty, or rotten. If you can track this smell back to your AC vents or your outdoor compressor then it’s definitely something you’ll want to take care of right away.

There are an array of possible causes, so it's a good idea to call in a pro to check it out.  It’s also important to be careful of any chemical smells coming from your system. This could indicate that you have a leak that may be toxic.

3. Inaccurate Thermostat

If the temperature on your thermostat clearly doesn’t match the actual temperature in the home, you’ll want to start by troubleshooting the thermostat itself. Some of the newer smart thermostats are complicated, and there’s a chance you just don’t have it programmed right.

Start by turning the thermostat all the way down and see if the HVAC unit comes on. If not, then you likely have a problem with the system rather than with the thermostat.

4. Strange Noises

If you hear strange noises coming from your HVAC unit, you could have a problem with the belt, a loose part, or other issues. Some of the sounds you’ll need to look out for include hissing, rattling, grinding, squealing, or clunking.

Generally, these issues should be handled by a professional tech as tying to handle these types of problems yourself could create a danger.

Scheduling heating maintenance services right away can help you catch a small problem before it turns into a major issue, so don’t make the mistake of ignoring any unusual sound.

5. Inconsistent Temperatures

Unless you have a multi-zone HVAC system, the temperature in your home should be consistent from room to room. If you find that one room is very warm while another is freezing, then you likely have a serious problem with your HVAC system.

If you have a multi-story home or commercial building, you may also notice that there’s a temperature variation between floors.

Likewise, if the airflow has slowed down for no obvious reason, this is an indication of a problem. Your HVAC system is designed for uniform flow at all times.

6. Drastic Increases in Your Power Bill

Has your power bill suddenly skyrocketed? While there are many possible issues causing this, you’ll want to check your HVAC system. This is especially true if you’ve noticed any of the other warning signs as well.

If the higher energy use is tracked back to your HVAC system, that means that your unit is working overtime to keep up. Not only is this wasting energy, but it’s also stressing your system. This extra wear and tear could cause your system to fail prematurely, which is an expensive problem that a maintenance call could help you avoid.

7. Power Fluctuations

Does your HVAC system turn on and off randomly throughout the day? This is also known as “short-cycling” and is potentially a dangerous situation.

One possible issue is that the machine isn’t getting enough power supply to keep running as it should. Left unrepaired, this could damage your breakers or even your entire home’s power supply.

Another possible issue is that your system is overheating. Once it cools down, the power supply will go back to normal. This will continue to happen in cycles, and, eventually, it could create a major fire hazard. For this reason, short cycling is an issue that you should never ignore.

Ignore HVAC Problems at Your Own Risk

The first step to troubleshooting HVAC problems is knowing what to look for. If you’ve noticed any of these red flags, you’ll want to check it out right away. In almost all cases, a small problem that’s been left untreated will turn into a much larger issue.

If you’re not confident with your ability to do a DIY repair, call in a professional to take a look. In this case, it’s better to be safe than sorry.

Great Tricks From The Experts For Troubleshooting HVAC Problems

You may be surprised to know that about three-quarters of homes in the United States have air conditioning. This figure makes sense because very few people are willing to sweat the summer away.

Calling HVACs lifesavers is an understatement. Thanks to these beauties, folks can enjoy cool summers and keep the draught away during winter. Also, we can use air conditioners to improve air quality because ACs filter excess dust and bacteria from the air to only circulate clean air.

In as much as air conditioners are lifesavers, troubleshooting HVAC problems can become a real headache. Fortunately, you don’t have to be a technological expert to troubleshoot the most common problems with HVACs.

This piece will highlight some incredible tips from leading HVAC experts on how to troubleshoot the most common issues with HVACs. That way, you’ll at least have an idea on how to go about it the next time your HVAC makes those weird noises.

The Working Principle of an HVAC

Before getting to the troubleshooting part, it might be helpful to know the underlying working mechanism of a typical air conditioning system. Don’t get your Physics course books yet; we’ll try to keep this explanation as concise and simple as possible.

Your HVAC system applies the same principle as your refrigerator in its operation. Now your HVAC probably has two units, one inside and the other outside the house. Although we typically have many types of HVAC systems.

The outside parts are as follows:

Vents- You’ll mostly find the vents near the ceiling. They distribute cooled or heated air to various rooms across the home. This air comes from the duct system, and these vents generally face downward and should never block.

Refrigerant lines- These are small duct lines that carry the refrigerant in gaseous form. This gas transforms into liquid then moves back to the evaporator coil to become gas again. Heat is lost and gained in this process.

The parts inside your home consist of the following:-

Thermostat- The thermostat is responsible for temperature regulation. It is the part you’ll interact with most as an HVAC owner.

Condensing unit- It is the unit that houses the refrigerant gas. This refrigerant is cooled to liquid then moved to the evaporating coil, where it transforms to gas again.

Evaporator coil- This unit cools down air when you set the thermostat to a lower temperature.

Furnace- The furnace is what brings the whole HVAC system together. The furnace heats the air, which the ducts then distribute to various rooms in your home.

The basic operation of an HVAC involves these processes.

First, air comes from the outside through the vents and ducts. Depending on the thermostat settings, the device will either cool or heat the air to a particular temperature.

This air is then distributed through the duct system to the various rooms. When air pushes into the coils for heating, air displaces from the room to the outside, then back to the system, and the cycle continues.

Troubleshooting HVAC Problems Like the Experts Do

It can be very frustrating when your HVAC doesn’t work as it should. No one likes a stuffy and uncomfortable room. It can be an especially embarrassing situation when you have guests over.

Fortunately, you don’t need to be an HVAC expert to troubleshoot some of the most common problems with your HVAC. All you need is the right tips form the seasoned experts, and you’re good to go.

Here are a couple of resourceful tips for troubleshooting HVAC problems you could try out next time your HVAC is giving you problems.

1. Uneven Cooling

Uneven cooling is a problem most homes face with their HVAC units. You may find that your HVAC cools parts of your home very well but doesn’t do a good job in some parts.

Sometimes it’s not an issue with the unit itself but your home’s sealing. Some regions may not have proper sealing, which allows for cold air to escape. 

Turn your AC ON and find a room that remains stuffy even with the AC working. Try sealing the room off to create even more efficient airflow.

2. Filters are Dirty

Dirty filters could affect how your HVAC system works quite significantly. Clean filters allow for better air circulation, which makes for quicker cooling.

To prevent dirty filters, you need to exercise proper HVAC maintenance practices consistently. That way, you’ll never have to worry about your filters getting dirty.

3. Coil Issues

Issues with the coils are pretty common among many HVAC units. Now depending on the severity of these coil issues, you may need to call in the experts.

Hissing noises from the outdoor unit could indicate a leak with the coil. You may also realize an unpleasant smell whenever you turn on the system. If your system also takes a while to kick in, it could also indicate an issue with the evaporating coil.

4. Ignition Problems

There are many causes of ignition problems. The most common is a dirty pilot flame or burners that can cause a pilot outage.

There could also be an issue with the gas supply. Whatever the problem is, it is typically challenging to repair ignition problems by yourself. You’re better off calling an expert to help you fix the issue.

5. Tripped Breakers

Tripped breakers go hand in hand with blown fuses. Your HVAC is an electrical machine with electronic components. Your fuse will most likely trip if the blower overworks.

It is up to you to figure out why the blower is overworking. The most common reason could be dirty air filters. Also remember, the more your blower overworks the more you pay for your power.

It’s best to get to the root of the problem soonest so you can save on your power bills.

Call the Experts When Needed

Undoubtedly you’re now a pro at troubleshooting HVAC problems. Remember to carry out the best maintenance practices and you won’t need to troubleshoot any of these problems.

Not everyone is an HVAC expert, so though you can troubleshoot the problem, you can’t always fix them. Don’t be afraid to call the experts whenever needed. That way, you can get everything fixed up the professional way.

R-22 refrigerant

No More HCFC-22: What to Know About the R-22 Refrigerant Phase Out

Did you know that since the 1970s, a huge ozone hole above Antarctica has been opening every spring? What's more, some areas of this hole showed a depletion of the ozone levels by as much as 65%!

Researchers also found that the hole grew to a size as big as North America. That’s about 25 million square kilometers!

The main culprits, according to scientists, are chlorofluorocarbons (CFCs), particularly hydrochlorofluorocarbons (HCFCs). These include the R-22 refrigerant used by most air conditioners back then.

Because of this, the Environmental Protection Agency (EPA) has ordered the R-22 phase-out. As of January 01, 2020, it's illegal to produce or import most HCFCs, including the R-22 Freon.

The question is, what does this ban have to do with you as a regular HVAC user? What is Freon anyway?

We'll answer all these questions (and more), so go ahead and read until the end!

What Is R-22 Refrigerant?

R-22 is the most common form of the HCFC-22 chemical, a type of Class II ozone-depleting substance. You likely know R-22 through the brand name "Freon".

As a refrigerant, HCFC-22 is the chemical that heats or cools the air that HVAC systems produce. When this fluid passes through the parts of the HVAC unit, it changes into either liquid or gas.

These transformations then make the refrigerant hot or cold. These changes make the chemical quick to absorb or radiate heat from the passing air. This is how your HVAC system cools or heats your home.

R-22 was the most common type of refrigerant used in HVAC equipment up until January 01, 2010. At this point, the EPA banned its production, import, and use except for existing equipment.

Meaning, if you have an HVAC system manufactured before January 01, 2010, then it likely uses R-22.

Determining What Type of Refrigerant Your HVAC System Uses

If you're unsure of your HVAC unit's manufacturing date, check the label on the compressor. This is the part usually installed outside of the home. The label will clearly tell you if it uses R-22 (HCFC-22) or R-410A (the refrigerant used in newer units).

What’s in Store for Homeowners With R-22 Air Conditioners

The January 2010 ban still allowed the production and use of HCFC-22 for existing units. This exception lasted up until December 31, 2019. This is how owners of HVAC systems that made use of R-22 were still able to get their units recharged.

However, as of January 01, 2020, the EPA has completely banned the production and use of HCFC-22. HVAC systems that still use R-22 would have to rely on "recycled" or "stockpiled" R-22 supply.

If you still have an R-22 AC unit, then you can expect higher refrigerant “recharge” costs. After all, the EPA ban means that the R-22 will become even scarcer than it already is. This scarcity will then drive up the cost of HVAC refrigerant "recharges".

In most cases, air conditioners need a refrigerant charge due to leaks. One solid sign that you have a leaking refrigerant is if your AC unit freezes up. An HVAC technician needs to seal this leak and then top up the refrigerant to make your AC work again.

However, now that the R-22 ban is in place, expect this HVAC repair job to be more expensive.

What You Can Do Now

Having an R-22 HVAC unit doesn’t automatically mean you need a new system right away. Again, the law still allows the use of such equipment. If you can't replace your current HVAC system at the moment, then make sure you at least do the following.

Regular HVAC Maintenance

You can prevent refrigerant leaks in the first place through proper HVAC maintenance. Many leaks occur due to corrosion, which can result from dirt and debris accumulation. Cleaning evaporator and condenser coils regularly can help keep corrosion at bay.

Prompt Repairs for Potential Refrigerant Leaks

Not enough cool air, frozen coils, and weird sounds are symptoms of refrigerant leaks. If you notice these signs of HVAC trouble, have a licensed HVAC technician inspect your unit ASAP. It's possible that there's only a tiny leak that the technician can still seal and repair.

Prompt repairs can prevent more of the pricey R-22 refrigerant from leaking out. This can then help extend the life of your R-22 air conditioning unit.

The Best Way to Address the R-22 Phase-Out

Granted, air conditioners can last between 15 to 20 years. This is also one of the reasons that the HCFC-22 ban still allows for the use of "recycled" R-22.

While you can still use your R-22 AC despite the ban, it doesn't mean that you should. Especially not if your current air conditioner is more than a decade old. Aside from likely being an R-22 user, such old units are more prone to breakdowns.

Over time, the repairs for these HVAC problems will add up to a considerable amount. The repair costs could be so high that it makes more sense to just get a new HVAC unit.

Besides, older HVAC models aren't as energy-efficient as the more modern units. By replacing your R-22 HVAC unit with an energy-efficient model, you can save 20% to 40% on cooling costs. These huge savings should be enough to make you consider getting a new HVAC system.

Time for a Change

As you can see, the R-22 refrigerant ban brings with it a host of changes that could affect your life as an HVAC owner. Despite its financial implications, however, this ban is actually great for the environment. That's why as early as now, you should consider swapping your old R-22-powered HVAC unit.

heater stopped working

5 Common Reasons the Heater Stopped Working (And What to Do Next)

Each year between 2012 and 2016, local fire departments in the U.S. responded to an average of 52,050 fires that involved heating equipment. To this day, heating equipment is still one of the leading causes of household fires, accounting for hundreds of civilian deaths every year.

While modern commercial and residential heating systems are often highly sophisticated and reliable, they are bound to develop problems at some point. When these issues persist, they can threaten not only the comfort of your loved ones but their safety as well.

But what if your heater stopped working altogether in the middle of the winter, leaving your family in the cold? It’s one of the most frustrating experiences you can go through.

The great news is that there are ways to minimize the chances of your heater not kicking on. And if the unexpected does happen, there’s always something you can do to address the problem. In this article, we look at five of the top reasons a heater can stop working, as well as how you can address the situation.

Read on to learn more.

1. Poor Maintenance Could Be the Reason Your Heater Stopped Working

Perhaps the top reason homeowners call HVAC technicians during the winter is lack of furnace maintenance. If your furnace won’t turn on, it’s almost always because you’ve not had it tuned for a long time. Often, the issue is that the heating system is simply dirty.

If your furnace has a dirty blower, the blower could cause equipment failure. The system’s heat exchanger cannot work unless there’s sufficient air moving across it to stop it from overheating. In short, a dirty blower can cause the heat exchanger to fail.

Dirty air filters could also be the reason your heater stopped working. Such filters restrict the airflow and could even worsen existing issues with wrong duct sizing. That’s why it’s paramount to replace filters every three months or so.

Lack of regular tuning could also result in a dirty flame sensor. That makes it hardly possible to light burners. A sensor covered in a layer of gunk cuts off the moment it turns on because it can’t sense the flame.

Sometimes, it’s the burners themselves that are dirty after a lengthy period of neglect. Such burners do not work well, if at all.

To avoid all these issues, you need to call a seasoned HVAC technician to tune your furnace on a yearly basis. In the long run, regular furnace maintenance is a worthy investment since it protects you from the inconvenience of a broken furnace. And even when the furnace does fail prematurely, you won’t need to worry about replacing costly parts.

2. Issues with the Thermostat

Another common complaint among homeowners is the thermostat not turning on heat. Usually, the root cause of the problem is that the thermostat is malfunctioning or improperly set.

The function of your HVAC’s thermostat is to regulate the amount of heat that’s generated by your furnace as well as when that heat is generated.  Most thermostats in the market today are quite reliable and will typically give you years of hassle-free service. However, every thermostat will eventually develop problems and require repair or replacement.

Once you discover that your current thermostat has a problem, consider replacing it with a programmable option. A programmable thermostat lets you choose different temperatures for various times of the day, night, and week. These thermostats are thus much more energy efficient compared to their non-programmable options.

Sometimes, the problem is that you wrongly programmed the thermostat. It could also be that you inadvertently reprogrammed it at a certain point. Check whether you've set the thermostat correctly before calling your local HVAC technician.

3. The Blower Capacitor Is Dead

If you’ve never seen the blower capacitor of your HVAC, it’s the part of your furnace that has the appearance of a big battery. The capacitor starts the furnace once the setting on your thermostat instructs it to start.

Every capacitor has a tolerance level. In case the tolerance level is lower than a specific level, the blower may not achieve the appropriate RPM.

Sometimes, the capacitor is dying or dead and won't start the blower. The simple solution is to replace it.

4. The Refrigerant Levels Are Too Low

If you heat your home using a heat pump, the refrigerant level of the pump can get too low. As a result, the heat strips keep coming on too often, leading to hefty utility bills.

When the refrigerant levels remain too low for a long time, the compressor could overheat and breakdown. That’s why you need to increase the refrigerant charge once you notice that the heat strips are coming on too frequently. It costs much less to recharge your refrigerant or fix leaks than it does to replace the compressor.

5. Faulty Ductwork Installation or Design

In some cases, the reason your heater isn’t working is not that the heater has a problem. The problem is with the ductwork.

Ensuring that the ductwork is properly designed and installed is a huge undertaking. Many installers, unfortunately, opt to cut corners when sizing ducts or installing them. You might get lucky and end up with ductwork that has been more or less appropriately sized and installed.

But when HVAC installers do a really poor job, you’re always going to have issues with airflow throughout your home. The heating system will most likely short cycle frequently. With time, it will overheat and break down completely

So how do you address this situation?

Your best option is to have a competent HVAC technician repair the parts of the furnace that have already failed. Next, the technician needs to redesign the ductwork, so the problem doesn't recur.

Don’t Let Heater Problems Linger

Heating systems can have a variety of problems, but a furnace that won’t work is arguably the worst. A furnace without power means that your family won’t have heat, which can result in discomfort and illness during the cold season. Once you know the reason your heater stopped working, it becomes easier to know how to address the problem.

trane heating and cooling

7 Benefits and Tips for Buying a Trane Heating and Cooling System

Trane is a company that everyone knows. They have been around since 1913 but started making heaters before that.

Throughout the twentieth century, Trane continued to innovate. These innovations helped to revolutionize the HVAC industry and change the way we approached heating and cooling.

Here are both reasons to buy a Trane heating and cooling system, and things you should look out for that will help you in deciding your next purchase.

1. Trane Heating and Cooling Dependability

Trane units have a strong dependability rating. This is not a new reputation, as they have been notably dependable for a century. Trane heating and cooling units stand up as well or better than any other brand on the market.

Nobody wants their HVAC system to break down. If you buy a Trane, you will experience fewer breakdowns. They scored an Excellent Rating, the highest attainable rating by Consumer Reports. This rating was achieved based on a survey of over 20,000 customers.

The number one reason for heating and cooling breakdowns is the lack of routine maintenance. Remember that any unit you buy, from any brand, will need regular maintenance. Make sure that you get your unit from a company that can both install it and keep it running for you.

2. Excellent Warranty 

Trane commonly ranks amongst the highest brands for customer satisfaction. One key to their incredible success is their warranty. While Trane heating and cooling systems break down less often than other brands, they have a reputation for always honoring their warranties.

Trane dealers are historically effective in repairing their units. This means that you can rest assured that if your unit does eventually break it will be repaired.

Their standard base warranty can last for up to 20 years depending on the part. Since most HVAC systems have a lifespan of only 15 years, you will be covered should something go wrong.

3. Get as Much Heating and Cooling as You Need

Trane offers a wide variety of models. These vary in size but make sure you are getting a system large enough for your home. 

Remember that you don’t need to get an excessively large heating and cooling system either. Doing this will help you save both in the purchase of the unit and in the monthly bills associated with your HVAC system.

This will also help you reduce the amount of energy your home is wasting. Using a Trane means that you will have an efficient system from the beginning. Doing your part means you will save even more on your bills.

4. Trane Has Traditional Heating and Cooling Units and More

Buying a Trane doesn’t just mean using traditional heating and air systems. While these are extremely popular, Trane offers more.

You can even buy a Trane heat pump to help heat and cool your home. These units are greener and offer you savings in the form of monthly utility bills.

Not all of these alternative models may be appropriate for you, so make sure you do your research. If you happen to live in Texas, there are several notable HVAC experts for Houston heating maintenance that can assist you.

5. The Innovative Design of Trane Systems

Trane has been doing this for over 100 years. That means they have the experience and understanding of HVAC systems that few can match.

Trane heating and cooling systems are typically ahead of the industry standard. When you buy a Trane, you aren’t getting just some “regular” heating and cooling system.

You are getting a system that has been built from the ground up by Trane. Every component has been tested and checked. Your system will be efficient and functional.

This approach is unique to Trane. Trane has been innovating technologies for heating and cooling for their entire existence. In fact, that’s what they started off doing. They got their first patents for water-based cooling systems in the 1930s!

6. A Quiet System

Central heat and air units can be loud. In fact, you can often hear your neighbor’s unit from inside your house. It can sometimes sound like an engine is being revved or a jet is flying over at low altitude.

That can be both annoying and problematic.

Trane heating and air units are among the quietest in the industry. If you live in a residential area where the homes are close together this can be especially nice. Your neighbors won’t have to hear your system going through the hot and cold months.

7. A Tradition of Trust

Trane is often called America’s most trusted heating and cooling brand. They developed this because not only do they build dependable and better products, they partner with the best people.

This combination of high-quality product and high-quality service make the experience of buying a Trane unique.

In order to get the most out of this benefit, make sure that you purchase your unit from a company that has a lot of experience. This is the best way to get the most out of your heating and cooling system.

Get a unit you can trust from a company you can trust and you will be satisfied and save money at the same time.

Houston Heating and Furnace Maintenance: 7 Tips to Get Ready for the Winter

With the chill wind picking up in the air, it is that time of year to get yourself settled in for the winter months. Between holiday prep, make sure you squeeze in time for furnace maintenance.

Making sure your furnace is well kept can do more than keep you warm in the winter months. It can also solve a lot of health and safety issues.

Need a bit help getting your furnace up and ready? Unsure of where to start or what to look out for? We have you covered!

Getting Ready for Winter with Proper Furnace Maintenance

Your furnace is an important aspect of your home. While it may only be on for a few months out of the year, if it is not ready for those few months, they can be disastrous!

In Houston, it is warm more often than not. As such, many forget the furnace even exists.

Such neglect means the machine will have a thick coat of hazardous dust and worn out pieces. With proper maintenance before winter is upon you, you can handle those problems before they grow into real issues. 

A quick safety tip! Whenever you are working on your furnace, be mindful of whether it has any sort of fuel to it. Remove the gas, unplug the power cord, or shut down any connectors.

Remove any possibility that it can turn on while you are working on it. You may save yourself some painful backlash. 

Now, let's go over the 7 easy steps towards proper furnace maintenance. 

1. Start Early

You never want to double-check you have all your supplies at the very moment you need them. The same works for your furnace. 

Even worse, in certain furnaces, a cold night can make your furnace hard to light, as heat can be harder to produce for that initial light. 

The best course of action is to start before you need it. That means you should aim to start your furnace maintenance checklist a month or two in advance, around August or September. 

If you are too late into the season, no worries! Later is better than never, especially when a cold front is breathing down your neck. As well, keeping up even earlier has its perks too. 

If you do maintenance twice a year, right as winter is winding down and again when it starts to build up, then each check will be easier from less buildup and wear. 

2. Visual Inspections Save Time

Sometimes the naked eye can catch a few items. It is always good to give your furnace a solid visual inspection. This can show you what pieces are dirty and what items look corroded or broken, among other things.

In gas furnaces, make sure that the venting pipes remain attached in the most secure way possible. For other types of furnaces, check for any clogs in drainage systems and such.

These quick checks can help you prepare for where your attention is needed most

3. Check Filters

Filters are the biggest and most important piece you will need to check during furnace maintenance. The most common issues with a furnace or any air quality unit are the filters.

A dirty or damaged filter can do a lot of things. It can restrict airflow, which will force your motor to work harder to get the warm air out. They can also contain piles of dust and grime which will fly into the air for you to breathe!

4. Clean and Clear Out

The next is to check all the ducts and tubes. You must clear out any ventilation systems of all dirt and grime. That is the last line for air systems and like the filters, dirty vents mean dirty air!

For natural gas and propane, some water will be in the system. The excess leaks out into a drip pan. You need to make sure you remove this water. If this pan overflows, your entire system will shut down!

5. Sealing Leaks

Any cracks or breaks in the tubing or vents will need filling and repair. Air getting out will cause damage to the system and raise your energy bills. Gas leaking from a broken pipe is even worse.

You can seal most cracks or leaks in piping with some molding putty, but be very careful about how the putty may react to heat. When in doubt, leave this to the professionals. 

6. Checking Safety Procedures

A modern furnace has a few odds and ends to make sure it operates in a safe and efficient manner. Check up on all these items to make sure they still function. 

The thermostat is the main one. Most people have a combined AC and furnace system, so you will notice if the thermostat has gone weird during the summer months. 

For gas furnaces, a flame sensor is a vital piece to keep your furnace running. Detach this from the furnace and give it an absolute clean. Your furnace should not even turn on without this sensor in proper order. 

7. Get the Proper Professional Finish

Furnace maintenance can be a major job. For a large house or an old furnace, cleaning your furnace can be a lot of work. As well, when things get damaged or in rough wear, you might need more experienced eyes.

If you are ever in doubt about whether you are getting your furnace the maintenance it needs, call a professional. Most services are quick, efficient, and if you catch them before the busy season hits, even affordable.

For the greatest of qualities, trust the locals for your furnace repair

Safe and Warm for the Winter

With the checklist checked and the steps followed, your furnace will have everything ready to keep you cozy. Furnace maintenance is one of those items on every year's list that needs crossing off, for your home and your family.

When you are as eager to keep your home as prepped and happy as you are for the holidays, we at P & M Air Conditioning and Heating are here to help! Contact us today for more information!

How Often Should You Get Houston Heating Maintenance Services?

houston heating maintenance

Most of us tend to take our daily comforts for granted, including a warm and cozy house in the cold winter months when the last place you want to be is outdoors.

Modern furnaces make it possible to hunker down for the winter and stay comfortable all season long. But if you've ever had your furnace break down, you understand how much you take it for granted and how quickly your home can become cold.

Maintaining your furnace year-round ensures that you won't have an unexpected breakdown when you need heat the most.

But how often should you get Houston heating maintenance done on your furnace? And what should you look for in a reputable technician?

Read on to find out:

How Often Should You Seek Houston Heating Maintenance

Even in areas that are warmer than others, we all depend on our heaters to work when we need them to on those cold days. But how often should have your heater checked out to keep it running all year long?

Most furnace manufacturers agree than maintenance should be conducted on a yearly basis. In fact, your furnace warranty probably mentions that damage done to your furnace as a lack of regular maintenance will not be covered. This is reason enough to keep up on your annual inspection.

And though chances are good that your technician won't find anything wrong with your furnace, it's still better to aim for prevention than paying for expensive damage.

What Happens During a Maintenance Tune-Up?

There's no industry standard when it comes to Houston heating maintenance, but the best technicians have a checklist that they adhere to. A technician you can trust will do a number of things including:

  • Check the venting system for any blockage that could lead to combustion or carbon monoxide. This is a very important step in the inspection because a blockage could lead to carbon monoxide poisoning of the house.
  • Check all the safety switches to make sure they're functioning properly so that your furnace won't overheat and start a fire.
  • Check all the burners to make sure they ignite.
  • Look at the drainage system to see if it needs to be cleaned.
  • Make sure all the wires are connected and free from corrosion.
  • Check the gas pressures, flame sensor, ignitor, and burners.
  • Check the filter for cleanliness or to determine if it needs replacing.
  • Inspection of the heat exchanger.

What you want is a thorough, responsible technician to perform your Houston heating maintenance. If a technician comes and checks your furnace and calls it good in a matter of minutes, they probably weren't looking at your system as well as they should be.

There are plenty of technicians that charge a very cheap rate to check your heating system but keep in mind that you really do get what you pay for, and in most instances where the rate is low, they aren't going through a checklist like the one above.

What are the Benefits of Furnace Maintenance?

As we've already mentioned, a furnace that isn't serviced regularly can stop working without warning. But it can also be a health hazard. By having your furnace checked out every year, your technician can prevent potentially serious problems.

Carbon monoxide leaks, for example, are nearly impossible for the untrained person to detect since the gas is both odorless and colorless. Carbon monoxide leads to dizziness, headaches, nausea, and possibly death. Thousands of people head to emergency rooms every year due to carbon monoxide poisoning.

When you keep up-to-date on inspections, you significantly reduce the chances of carbon monoxide poisoning and keep your family protected.

Another benefit of bothering with an inspection is savings. Though you might be tempted to avoid the initial cost of inspection, it's a small expense compared to what you could end up paying in repairs. The difference can be hundreds of dollars in savings by opting for preventative costs versus big future repairs.

Inspections also save energy in the long run. Your technician can do most of the work for you, but as a homeowner, you can take charge by changing your air filters every three months to avoid clogged air filters and restricted airflow.

Be sure to ask your HVAC professional about the benefits of a programmable thermostat if you don't already have one. Having one in place can save you a chunk of change on your energy bills.

New Systems Still Require Maintenance

Don't make the mistake of assuming you don't need to bother with maintenance because your system is somewhat new.

Your manufacturer will likely require you to keep up regular maintenance and keep a record of such before you can make any warranty claims. So it's not only important to keep those maintenance efforts going for the longevity of your system, but for the sake of your warranty as well.

Contact Us to Schedule Your Maintenance Appointment

Now that you understand the importance of regular Houston heating maintenance efforts, give us a call today to schedule your next inspection.

We'll come to check out your furnace system to make sure everything is running smoothly and we'll answer all your questions along the way.

And don't wait until the cold weather is already upon you! Take advantage of our professional services right away so you can rest easy knowing your home is ready for winter and the air you're breathing is safe and sanitary for months to come.

7 Affordable Ways to Come Home to a Warm House This Fall and Winter

Winter is approaching and you must be thinking of how to not only keep your house warm but do so in an affordable way. Homeowners are regularly advised to overhaul their inefficient heating systems, install double glazing, and use thorough insulation, but these are expensive tactics.

You need cheaper and quicker ways to keep your house warm. With summer coming to an end, fall and winter’s cold is just around the corner. Leverage these 7 tips to ensure that you can come home to a warm house.

1. Stop Heat Loss up the Chimney

Make good use of your fireplace during winter. There’s a possibility that you could be wasting a lot of heat energy from your fireplace via the chimney. This can be very costly because so much firewood would go into waste as you struggle to keep your house warm.

To prevent this heat loss, consider using a chimney balloon, which is used to block the opening of a chimney to save energy by stopping chimney drafts. It is made of a durable, reactive laminate and is very affordable.

All you need to do is to place it inside the chimney then inflate it until it fills the chimney opening; this helps in stopping any escaping heat or incoming cold air.

2. Upgrade Your Boiler

If you’re using an old boiler in the house - more than 10 years old - then it is high time you replaced it with a modern model. The new A-rated boilers are very efficient because they use smaller amounts of fuel or gas to produce larger amounts of heat energy.

3. Let the Sunlight in During the Day

Sunlight is a natural source of heat that doesn’t cost anything. You can make good use of it by ensuring that during the day, you capture as much heat from the sun as possible. To do this, open up all your curtains in the morning to let sunlight in.

You only need to open the curtains that can block sunlight from your house and leave those that don’t block any sunlight. Once the sun goes down, close all the curtains to keep the heat from escaping through the doors or windows.

If you are in a region that gets extremely cold during winter, you can consider purchasing insulated curtains to help keep the house warm. You can even put some temporary curtains, rugs, or sheets over the doors and windows to the outside at night while you’re sleeping.

These will offer some insulation and keep your house warm.

4. Mitigate the Stack Effect

Stack effect is a principle in physics which explains the movement of air in and out of buildings. As the air in the house gets warm, it will rise and this will create some negative pressure in the lower levels of the house.

The low pressure will by the laws of nature cause the cold air from outside to move into the house through any available openings. Stack effect is worse in the tall buildings because as more warm air rises, more cold air will be pulled in.

To mitigate this and have a warm house, you need to seal all the gaps that can allow cold air into the house, especially those at the lower levels. Check the bottom of your doors for any gaps and seal them using some rags or door snakes.

You can also check for any gaps in windows. To test for these gaps, hold a lit candle close to the places you suspect and observe how the flame behaves. A flickering flame is an indication that there’s some air leakage.

Do not ignore even small gaps; the cold air that comes in through such gaps throughout the night can cause lots of discomforts.

5. To Get a Warm House, Use the Oven More

Broiling, convecting, and baking things is the best way to keep your house warmer, particularly the rooms closest to the kitchen. It might be true that you don’t use your oven much during the summer because it makes the house hotter, so during winter take advantage of the oven to supply heat into the house.

Don’t be afraid to bake tons of cake and roast chicken when temperatures dip.

6. Move Furniture Away from Vents

Check all your furniture to see if there’s any that you placed in front of heating vents. If so, move the furniture away from the vent, at least for winter. You can return them to their position during the summer.

If some heating vents are blocked, some rooms will not get their maximum heat potential.

7. Install a Programmable Thermostat

Installing a programmable thermostat will ensure that your house is only heated when necessary. Installing one will ensure that your energy consumption is efficient and your monthly bills are low.

Furthermore, a programmable thermostat will save you a lot of time. You’ll not have to manually turn it off every time you are leaving the house and switch it on or adjust it every time you are in the house - the automated thermostat will do the job for you.

A programmable thermostat allows you to set the temperatures exactly the way you want them to be and for a time duration of your choice. You can even program it for a whole week.

If you can get a smart thermostat, even better. This device can detect the ambient temperature and respond accordingly. It can also detect when you leave the house and when you get back in.

A Warm House Is Good for You and Your Family

A warm house is beneficial to the well-being and health of your family. Cold houses are linked to poor health, particularly in young children. Keeping your house warm will not only make it cozy and homey but also beneficial to your health.

It is cheaper to keep the house warm than to spend on medical bills. If you are in need of professionals to install, maintain or repair air conditioning and heating services, be sure to check out our page.
