While today’s HVAC systems are built to deliver years of dependable service, inevitably problems with air conditioning ranging from the simple to the complex can and will arise. Here are several of the most common issues reported by homeowners and their HVAC service professionals:
Air filters should be changed regularly. Otherwise airflow can be reduced significantly, which can cause your HVAC system to underperform and eventually freeze.
A common problem caused by dirt and other organic materials building up in the lines, this can cause water to back up in and ultimately overflow the drain pan—potentially damaging system components.
If your HVAC system isn’t working, a breaker could have flipped off. Fuses are designed to protect your unit’s motor and compressor from overheating. A blown fuse may be a sign of a larger problem with your system.
Whether in the lines or in the coils, refrigerant leaks are often caused by system vibration during operation. If your system’s refrigerant requires recharging, you have a leak that requires repair.
Located outside the home and exposed to the elements, condenser coils should be cleaned yearly. Failure to do so can negatively impact system performance.
Faulty wiring or worn contactors can be the cause of system outages and should be checked periodically.
Obstructed air returns or clogged air filters can restrict airflow and cause the evaporator coil inside your home to freeze up. Low refrigerant level can also cause this problem.
These control devices can stop working and require replacement. You can also inadvertently turn them off or not have them on the correct setting for the season or your indoor comfort preference.
