What is Compressor?
The compressor is the heart of an air conditioner or heat pump — the pump in the outdoor unit that pressurizes refrigerant and drives it through the system so heat can be absorbed indoors and rejected outdoors. It's also the single most expensive component to replace.
Why it matters in Arizona
Desert duty is brutal on compressors: near-continuous summer running, 115° condenser air, and monsoon power blinks that force restarts against pressure. A failed compressor on a 10+ year-old system is usually the moment replacement beats repair — that's the $5,000-rule scenario.
