-
Compressor tests: We check windings, amp draw and the start components with a meter.

Why Compressors Fail in Davis
Compressors work hardest during Davis heat waves, and local conditions add stress.
-
Long, hot runtimes: An average Davis summer reaches 100°F on 15 to 20 days, and the record is eight days in a row, so the compressor rarely gets a rest.
-
Dirty coils: Dust and cottonwood fluff coat the outdoor coil, raising pressure and heat inside the compressor.
-
Low refrigerant: A slow leak makes the compressor run hot and wear out early.
-
Age: Many units installed from 2010 to 2015 are now at the age where compressors fail.

Check the warranty: Compressors often carry a longer warranty than the rest of the unit.
-
Quote both ways: You see the repair price beside the cost of a new system.
-
Replace the compressor: We swap it, add a new drier and braze with nitrogen flowing.
-
Recharge and test: We charge by weight and measure the cooling.
