Came out to perform preventative maintenance on AC system. Discussed with customer about maintenance being provided, filters, and any issues he may be having. Customer stated system has been working well and that he will take care of the filters. Discussed with customer about benefits of adding more insulation in the walls and attic, and any affect it has on the AC system. Advised customer that the system would most definitely benefit from the insulation, and that it would help increase efficiency. I did a thorough inspection on all parts of the system. Inspected the blower assembly, electrical components, evaporator coil, drain, ductwork and overall condition and operation of equipment in garage closet. Cleaned condenser coil thoroughly. Checked thermostat operation, wiring, capacitor, contactor, compressor, fan motor, amps, temperatures and pressures of condenser. AC is cooling properly within manufactured specifications at this time.
