The most common problem is a frozen evaporator coil. This problem occurs when the AC doesn’t receive enough air to function properly. The frozen coil, in turn, can jam the AC and stop it from working or invite contaminants into the indoor air. This problem can occur due to many reasons including blocked ducts, vents, dirty air filters, and faulty fans which prevent enough sit from reaching the evaporator coil. The coil is up and eventually freezes. The best way to prevent this issue is to maintain a clean filter, to allow maximum airflow into the AC’s hardware.

If you provide proper maintenance to the AC unit, it can last a surprisingly long time. You can expect your AC lifespan to be anywhere between 10-and 15 years unless you experience repeated problems with the unit. To ensure a long life, make sure to clear the filters periodically and ensure proper storage. Look out for the following signs to see if a repair is needed. Your AC isn’t giving off enough cool air, the airflow isn’t as strong as usual and the entire room isn’t cooling up, you notice moisture and leakage around the unit, and when you hear an unusual sound coming from the AC
