If this happens to you, there is a silver lining in this cloud and it’s as simple as calling McQuerry’s 24- Hour Heat and Air. The professionals at this company are experts and are well-trained to fix common HVAC problems. Below you will find seven of the most frequent HVAC issues that can occur to your unit:

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.

Thermostat Not On

The thermostat is one of the most important components of your unit. However, this item must be turned on in order for your system to work properly.  Be sure that you have the correct setting on your thermostat before reaching out for professional assistance.

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 professional HVAC company, the technician can clean them properly.

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.

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.

Blown Fuses

These are found in the evaporator coil and work to protect the motor or compressor from overheating. It is possible for one of these to go out, and it’s typically one of the first items that are checked by a service technician.

Refrigerant Leak

It’s possible your HVAC unit may be leaking refrigerant. This can occur because of the vibration of your unit and may result in problems for you. If there is a                leak found in the evaporator coils or condenser, these can’t be repaired. However, if the leak is in another part of the unit, it’s typically easier to fix.
