In general, HVAC systems are reliable without any operational problems. Like other automatic systems, they also have certain limitations needing timely maintenance. Having to deal with common HVAC problems can be quite frustrating but common HVAC problems should be dealt with on an immediate basis to avoid bigger issues with the system later down the road.
Let’s discuss a few of the common HVAC problems and their solutions.
#1 Common HVAC Problems: I’m having a problem with my HVAC filter
This is one of the most common problems which occur when there is clogging or blockage in HVAC filters. When this happens you should change the filters immediately.
If you choose not to change your filter, the dirty filter can lead to a reduction in the airflow causing the unit to freeze.
#2 Common HVAC Problems: I’m having a problem with my HVAC condenser coil
The condenser coils are placed outside the HVAC unit along with the compressor. This can cause the condenser coil to gather a lot of dust. To clean your condenser coil use a water hose to rinse it down when the system is turned off.
If you choose not to clean your condenser coil the problem could cause your compressor to stop functioning properly and parts could break. To know if your HVAC system needs new parts or cleaned, it’s a good idea to contact a local Maryland HVAC technician to come to your home and inspect the machine.
#3 Common HVAC Problems: My HVAC compressor stopped working
Since the compressor is the main part of the HVAC unit it should be maintained and kept in the best possible condition year-round.
If you’re noticing problems with your compressor not functioning there are a few things you can check before you get a technician involved.
Refrigerant liquid: When the HVAC system is undercharged with refrigerant liquid, the compressor becomes extremely hot and stops operating eventually. When it is overcharged, the liquid refrigerant goes back into the compressor leading to liquid slugging and a non-functional compressor.
To avoid this, make sure the compressor has the proper amount of refrigerant liquid. Taking the expertise of HVAC technician for understanding the correct amount of refrigerant and other precautions also help in maintaining the optimal performance of the compressor of the HVAC unit.
Evaporator blower motor: The evaporator blower motor works with a contractor and capacitors. They need timely checking to ensure proper functioning. A blown fuse can also be a problematic area with the compressor and the condenser fan motor. The function of the fuse is to protect the motor against overheating.
To deal with the problem, it is suggested to replace the blown fuse immediately to maintain the proper functioning of the HVAC system.
Other HVAC problems you can look for:
- Leakage in the cooling tower
- Clogging of the duct system
- Freezing of the evaporator coil
- Non-functioning of the boiler system
Now that we’ve outlined a few of the issues and their solutions, we hope you learned something and can use this knowledge in your household. If a problem occurs that needs the help of a technician, the technicians at BMC Clower await your call!
