What Air Conditioning Services technicians do
Air conditioning service technicians are EPA 608-certified professionals who diagnose and repair central split systems, ductless mini-splits, and packaged cooling units. Their diagnostic process starts with a refrigerant pressure test to identify charge loss or compressor faults, followed by an electrical panel scan for burned contactors, failed capacitors, and high-voltage wiring issues. Technicians measure evaporator coil superheat and subcooling to verify charge accuracy, test condensate drain flow and float switch operation, and document system performance against the original SEER2 rating before closing the work order.
