Upon arrival the homeowner had complaint of AC not keeping up. I checked thermostat operation - normal operation . I checked amps on blower and they are within spec. I checked the blower wheel - clean and clear. The bearing are tight. I checked the blower motor capacitor and it is within spec. At the condenser the pressures are great! Checked amps on compressor and amps on fan are within spec. I checked dual capacitor and within spec. Condenser coil needs rinsed with water, quote $99, homeowner was to do this himself. Everything was fully operational when leaving.
