5 Most Common HVAC Problems

5 General HVAC Problems

Common HVAC ProblemsWhen your HVAC is not working, it can be very frustrating. The professionals at McQuerry’s 24-Hour Heating want to help, and are experts at fixing both uncommon and common HVAC problems. The following are five of the most common problems that homeowners might encounter with their HVAC system:

1. Clogged Filters

The filters in an HVAC unit assist in keeping the air that blows out clean. They can get grimy and clogged with air particles if not changed regularly. Most HVAC companies suggest changing them every 30-60 days. Clogged filters can result in dirty air circulating in a home, and ultimately freeze an HVAC unit.

2. Thermostat Not On

The thermostat helps regulate the temperature of a home, and can be set to turn on and off. Sometimes people think their HVAC is not working, when actually the thermostat is turned off or incorrectly programmed.

3. Dirty Condenser Coils

The condenser coils are located in the compressor, which is outside of the house. They can easily get dirty since they are exposed to the elements year round. Condenser coils should be cleaned with water at least once a year. If you schedule an annual maintenance appointment with a St. Louis, MO HVAC company, the technician can clean them properly.

4. Blocked Drain Lines

Another of the most common HVAC problems is when the drain of an HVAC unit gets stopped up with dirt and algae. When this happens, the drain pan will overflow with water which can cause damage to carpet and wood floors, and can stain the ceiling below. McQuerry’s 24-Hour Heating can assistance you if you have a clogged drain line.

5. Corroded Gas Valves

Gas valves are only in use when the heater is on, and control the flow of gas to the HVAC. If they become corroded they may stop working and need to be replaced.
