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.
