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.
The blower fan in the indoor unit circulates cooled air into the room. Dust accumulation on the barrel fan and bearing wear cause the motor to become noisy, inefficient, and eventually fail. When it stops, no air circulates despite the compressor running.
