Wear & Age

Half of all AC failures come down to parts that simply wore out. Compressors, fan motors, and capacitors all have finite lifespans — the older the system, the higher the odds something gives.

What breaks most often

Run capacitor16%
Cheap part, the single most common failure on residential AC. Bulges or fails open and the compressor won't start.
Compressor13%
The heart of the system, fixed-speed or inverter. When it goes, the whole condenser usually goes with it.
Condenser fan motor11%
Outdoor fan seizes or burns out. System runs but can't reject heat — pressures spike.
Contactor pitting10%
Burned contact points cause hard starts and chatter; eventually weld shut or fail open.
