The most common failure types, sorted by when they typically appear.
The AC removes humidity as it cools, producing condensation that drains through a pipe. Algae, mold, and debris clog the drain, causing water to back up into the drain pan and potentially overflow, causing water damage to ceilings, walls, or floors.
When airflow is restricted (dirty filter, blocked vents) or refrigerant is low, the evaporator coil drops below freezing. Ice forms on the coil, further blocking airflow in a vicious cycle. The AC blows warm air or stops working entirely. Often a symptom of another issue.
Start and run capacitors provide the electrical surge to start the compressor and fan motors. When a capacitor fails, the AC may hum but not start, or the compressor may struggle to engage. This is one of the most common and affordable AC repairs.
