8 Common Thermostat Problems Houston, TX Homeowners Have and How to Fix Them

The average American family spends around $2,000 on energy costs each year, and more than half this amount is for heating and cooling costs. It costs money to heat and cool a house, but some people spend more than they should. For example, you might use more energy if you have an outdated furnace. You might also pay more if you have thermostat problems.

Many homeowners don't realize the role and importance of their thermostat, and they might not realize how many issues they can have from problems with this device.

If you'd like to learn more about thermostat problems, you'll want to continue reading. Here is a guide that explains eight common issue's people in Houston, TX, have with their thermostats and how to fix them.

1. Bad Calibration

A thermostat operates by telling your HVAC system when to kick on and off. You set the temperature you desire, and it connects to the furnace.

Unfortunately, a thermostat can only operate accurately when it's properly calibrated. Calibrating a thermostat means matching up the correct temperature to the settings.

For example, if a thermostat thinks that 70-degrees is 80-degrees, your heating system won't heat your home enough. Your thermostat's reading is wrong in this case, though, which means it has a wrong calibration.

There are many types of thermostats you can choose from for your home, and each might require a different calibration process. If you don't know how to calibrate yours, you can hire a heating company to do it for you.

Before they calibrate it, they'll test it to see if it's accurate. If the temperature is accurate, the calibration is fine and won't need adjustments.

2. Poor Location

If your house is too hot or too cold, it might be due to your thermostat location. A thermostat's placement is critical for heating and cooling a home properly.

For example, if your thermostat is by a drafty window, it might cause the temperature on the device to drop. As a result, your furnace will run more, causing the rest of your house to feel too hot.

On the other hand, if your thermostat is by your kitchen or fireplace, it will cause the temperature to show up higher on the device. As a result, your furnace will run less, leaving your home too cold.

A heating and air company can move a thermostat if its location is not ideal. When doing this, they will look for an area away from hot and cold things. In addition, they'll ensure that it's also in a draft-free area.

Moving a thermostat can make a big difference in feeling comfortable in your home. It can also lead to energy savings, as your HVAC system will only run when necessary.

3. Low or Bad Battery

One of the most common thermostat problems homeowners face involves a dead battery. Most thermostats operate from battery power. But, unfortunately, a battery won't last forever.

You can usually tell when the battery is going bad by looking at the thermostat. The numbers and letters on it might start fading or dimming. If you see this happening, it's a sign to change the battery.

Additionally, if your thermostat stops working and doesn't show anything on it, it's probably because the battery is completely dead.

Replacing a thermostat battery isn't difficult, but it requires removing it from the wall. You should find a small battery panel on the back when you remove it. You can open this panel and replace the battery to see if it works.

If this fixes the problem, you won't have to contact a heating company for a service call.

4. Display Not Working

A bad battery can cause a thermostat's display to stop working, but that's not the only cause. The other thing that might cause this is a bad thermostat.

Thermostats don't break too quickly, but they also don't last forever. So if replacing the battery doesn't fix the thermostat, you might need to replace the device.

Replacing a thermostat isn't something you should do yourself. Instead, hire a contractor to replace it. You can upgrade to a smart thermostat when replacing it if you don't have one yet.

5. Bad Wiring

Bad wiring is another problem you might have with your thermostat. Bad wiring might cause the display to stop working, but it can also cause the thermostat to miscommunicate with the furnace.

For example, if your furnace is running at times when it shouldn't be, there is a chance it's from bad wiring. Additionally, if your furnace won't run at all, it could also be from bad wiring.

A heating contractor can test and trace the wires to determine if this is the problem. They might have to reconnect wires or replace them to fix the problem.

6. System Not Producing the Right Air Temperature

Another problem you might encounter is your system not producing the right type of air. For example, if your system blows hot air when it should blow cool, you might wonder what is happening.

One thing you should check is the setting on your thermostat. Your thermostat might have several settings, including heat, cool, and fan.

The furnace won't work properly if you have it on the wrong setting. You should adjust your thermostat to fix this problem.

7. Thermostat Not Turning on When It Should

You might also encounter a time when your HVAC system turns on when it shouldn't. For example, if the temperature in your home matches the thermostat's setting, the furnace shouldn't turn on.

If your system runs at times when it shouldn't run, you might have a problem with the calibration. Additionally, the wiring could be bad, or the thermostat might be worn out.

8. Programmable Issues

Finally, if you have a programmable thermostat and encounter problems with the settings, you might need to find the manual. You can read through the manual to update or adjust the settings.

If you're still having problems programming it, you might need to hire an HVAC company for help.

Thermostat Not Working? Here's What To Do

At some point in our lives, we have all felt what it is like to experience thermostat problems. Depending on where you live, that could entail no cool air in the middle of summer or no heat during the winter. Texas is one of the hottest states in the country, so when your cooling system doesn't do its job, it can leave you in an uncomfortable situation. Luckily, there are a few things you can do to check before hiring professionals. Thermostat not working?

It's likely due to needing a battery replacement, but there are other possible causes. Learn what they are and what to do here.

Check the Power to the Thermostat

When your thermostat goes out, the first thing you want to do is check the power. Depending on what kind of thermostat you own, it may run on either AA or AAA batteries. Others work off of the power supply given off by your home's HVAC system.

To start, you'll need to identify which thermostat you own. If you suspect the batteries are dead, change them out and turn your thermostat back on. If it doesn't boot up, there may be another issue.

If you have a thermostat wired to your house, head to your breaker panel to check you haven't tripped a breaker. If you have, resetting the breaker is a simple fix.

However, if you blew a fuse, the Occupational Safety and Health Administration advises that unqualified personnel should not try to reenergize the circuit or fuse. That is because this poses a risk. So, if you suspect a fuse, be sure to call in a professional.

You also want to keep in mind that some thermostats work on a time delay. That means that even if it is your batteries or circuit breaker, the AC system may not boot up right away. Give it a few minutes to get going before you decide that it is faulty.

Check the Age of the Thermostat

The average lifespan for a thermostat is about 10-15 years. Age is one of the most common thermostat errors. So, check to see when you installed it.

If you live in an older house, look to see when the previous owners installed the thermostat. One way to tell age is whether the unit is digital or not. Most modern thermostats are digital, some with a touch screen.

Older systems are manual and may have dials or buttons on them. There is a chance that your thermostat is failing due to old age. If you suspect this to be an issue, then you might have to look into buying a whole new system.

If you have an old thermostat, then it contains mercury. Be sure not to throw it in the trash, as this is harmful to people and the environment.

Mercury poisoning can cause serious health effects to anyone exposed. Instead, be sure to recycle. That way, the mercury is handled by professionals.

Check the Mode of the Thermostat

It seems like a no-brainer, but go ahead and double-check the settings on your thermostat. Many people tend to jump to the worst possible conclusion when all that needs fixing is the mode.

If your AC is blowing warm air, make sure your thermostat isn't set to heat. That is an easy mistake to make, especially with digital thermostats. You can accidentally hit other buttons without realizing it.

Check the Temperature Setting

Along with the mode, you want to check the actual temperature setting. Look to see what the degree says on the unit. Some people like their homes to be a cool 74 degrees.

But your AC won't work if you accidentally set it higher or if you don't hit the necessary buttons. For instance, some thermostats require you to hit 'enter' before it starts cooling your house down.

Check the Calibration

Did you know that the placement of your thermostat system affects the unit's performance? Many people do not realize this, but the location is everything to keeping your system calibrated.

For instance, if your thermostat is near a window, then the sunlight may hit it and throw the temperature off. The same is true if you set it too close to a hot lamp or if there is a particularly drafty area in your home. To avoid misplacing your thermostat, speak to a professional who can assess your home and tell you the best location.

What are the Benefits of a Ductless HVAC System?

Have you noticed that some rooms in your home have a different temperature than the rest of your home? Then you should consider installing a ductless HVAC system. The primary reason why you may be experiencing this problem is your AC unit isn't providing a consistent level of comfort.

The ductless systems are efficient and offer consistent comfort in every room. The ductless system usually consists of a wall-mounted indoor unit attached to an outdoor compressor via a small 3-inch hole for power and refrigerant lines. Now let's get into the top benefits of going duct-free.

Quiet Operation

Typically, a ductless air system consists of both the indoor and the outdoor components. Therefore, contractors usually install the noisy elements of the system such as the motor and the compressor outside. In fact, you won't believe how quiet these ductless systems are while in operation. The ductless system will operate at approximately 26 decibels which is quieter than even the average whispers in a library.

Increased Comfort

When you are installing the ductless system, you determine where you want to place it and how many units you prefer for your home. You can put it in any part of your home you wish. Since we have already established that different rooms in your home record different temperatures, you place the unit in a strategic place to boost the overall comfort of your home. You can have more than one unit and install them in different rooms.

Energy Efficient

Every homeowner would love to make their home energy-efficient to cut down on energy bills. Typically, more than 30 percent of energy consumption in your home is through the traditional ductwork. The ducts tend to consume a lot of energy even before the conditioned air reaches your home. With the ductless systems, you are getting 100 percent of the unit’s output. The energy saving of a ductless system goes beyond the system’s output. Since you are heating or cooling the required rooms only, you use less energy.

Environmental Friendly

Apart from being energy efficient, the ductless system also operates on the R410A refrigerant which is specially designed to prevent damage to the ozone layer. Since your home is also energy-efficient, its overall negative impact on the environment is significantly reduced.

What Are Different Types of Thermostats?

Do you know which type of thermostat to buy? A thermostat is a device which controls the temperature of cooling and heating devices. We sell quality thermostats in Houston, TX. Here is a highlight on the various types of thermostats you can purchase.

Manual Mechanical Thermostats

It is a traditional thermostat variety. Once a homeowner sets it at a particular temperature, it remains constant until they manually switch it off. Also, it remains turned off until one manually turns it on. Moreover, you should manually switch it from cooling to heating or heating to cooling mode. However, many people no longer use them as they have mercury.

Manual Digital Thermostats

They typically use a solid-state temperature monitoring tool, a thermistor, which senses a room's temperature. It energizes the equipment through a circuit board or user settings. One can efficiently use them if they are knowledgeable in HVAC electrical control. When you intend it replace the thermostat, it recommended that you hire a certified HVAC technician. It avoids creating electrical problems such as faulty wiring.

Programmable Digital Thermostats

They offer essential and multiple functions for a variety of HVAC equipment. Some thermostats may be challenging to operate while others are quickly programmable. However, it's vital to understand different thermostat programs and to read their user guides.

Programmable Mechanical Thermostats

They have been in use for decades. Most HVAC stores no longer sell them. The thermostat operates through its mechanical timer, multiple switches, and user settings. It has a mercury switch that completes its circuit. Also, most American states have banned their sale. They have established laws that regulate the disposal of these thermostats.

More types of thermostats include:

  • One-Stage Cool and Heat: Single-stage thermostats are used for packaged units and split systems
  • Two-Stage or Multi-Stage: Appropriate for heating and cooling equipment that automatically adjusts output capacity to match the existing load
  • 24mV Controls: A 24mV thermostat is usually installed in modular cooling and heating units or appropriately equipped fireplaces.
