More often than not, HVAC systems are reliable and can last for many years but just like any other appliance, problems can crop up from time to time. At such a time, you need a licensed electrician for HVAC repair. Knowing the common types of HVAC problems enables you to fix them in case they occur.
1. Clogged Filters
HVAC filters assist in cleaning the air that blows out which makes them susceptible to becoming clogged. If they are not changed regularly, it can result to dirt circulating in your home and ultimately lead to the breakdown of the HVAC unit. Most manufacturers recommend changing the filters every 30-60 days to prevent clogging.
2. Thermostat not turning ON
The thermostat is an important part of an HVAC unit. It is used to turn the unit ON and OFF as well as control the temperatures. Before turning it on, ensure that the thermostat is set correctly to cool or heat.
3. Dirty Condenser Coils
The condenser coils are located in the compressor outside the house meaning that they can easily get dirty as they are exposed to different outdoor elements all year round. For this reason, they should be cleaned at least once in a year. You can schedule a yearly maintenance appointment with a professional company to have them cleaned properly.
4. Blocked Drain Lines
Another type of HVAC problem is when the drains from your unit are clogged with algae or dirt. This makes the drain pans to overflow with water leading to damage of your floor. It can also stain the ceiling below.
5. Corroded Gas Valves
The gas valves control the flow of gas to the HVAC, and they are only in use when the heating unit is ON. If they become corroded, they no longer work as efficiently and require replacement.
6. Blown Fuses
Fuses are used to protect the compressor or the motor from overheating, and they are located in the evaporator coil. It is possible for one of the fuses to blow leading to a faulty unit. Fuses are the first items checked by a technician.
7. Refrigerant Leak
It is possible for the refrigerant of your HVAC to leak because of the vibration of the unit. If there is a leak in the condenser or the evaporator coils, they can only be repaired by a professional. However, a leak in other parts of the unit is easier to fix.
