To check an AC compressor, for both normal and inverter types, first inspect for physical damage or leaks. For normal compressors, use a multimeter to test continuity between terminals. For inverter compressors, check voltage output from the inverter board. Listen for unusual noises and monitor cooling performance for both types. #ACCompressorCheck #InverterAC #HVACDiagnostics #CompressorTesting #ACRepair #MultimeterTesting #CoolingEfficiency #InverterTechnology #ACMaintenance #HVACExpert #CareS
