Learning About Furnaces

4 Common HVAC Problems

Being able to stay warm in the winter and cool in the summer is sure to be something you'll want to accomplish. It's important to stay comfortable year round in your home and this may require the use of your HVAC unit to do so. It's ideal to avoid any type of unit failure if possible. Knowing some of the most common HVAC problems that typically occur may help you be prepared for these in advance.

Refrigerant Leaks

If the air in your home isn't getting as cool as you'd like it to be, you may have a refrigerant leak. These are commonly caused by all of the vibration that occurs when your unit is in operation and may be more severe with frequent use.

It's important to note that if the leak occurs in the evaporator or condenser coils, it will not be capable of being repaired. However, if the refrigerant leak is found in another area of our unit, this can typically be fixed.

Compressor

This is what keeps the unit running well and if the compressor overheats, you could have a problem. One of the main reasons a compressor can get too hot may be the lack of refrigerant that is needed to keep it cool.

Gas Valve

During the winter months, you may rely on the gas to keep your home warm. One of the main components that is necessary to do assist in doing this is the gas valve. This may become corroded over time and with consistent use. If so, these may need to be replaced by a professional.

Contactors

Most HVAC units have three contactors that are necessary to keep the unit operating as it should. There is a contactor for the compressor, blower motor and the condenser fan. All of these components will work together to provide your home with the cool or warm air that is necessary for your comfort.

Any of these three contactors could become worn out and this could decrease the possibility of your unit running as efficiently as it should.

The key to keeping your HVAC unit running as well as it should is by getting your unit serviced at least once a year and addressing any problems as these may arise. Be sure to rely on the expertise that is offered by an HVAC professional, such as Drew Green Heating & Cooling, to repair any problems that you may encounter with your unit.
