Came out to perform preventative maintenance service for gold club member. Discussed with customer about maintenance needed and also about filters and how the system is doing for them. Customer asked that I change the filters for him, and he supplied them. He also asked about a setting on the thermostat that notifies him about the filters needing to be changed. He already writes it down, so he wanted that feature disabled, so he doesn’t have to go through the manual to figure out how to reset it. I turned the filter reminder off and also set the back lighting to always on, so the customer can see the screen at all times. Started the maintenance with checking the equipment in the attic. I inspected the blower assembly, motor, electrical components, evaporator coil, drain and overall condition of equipment. Washed condenser coil thoroughly. Checked thermostat operation, wiring, amps, temperatures and pressures of AC. System is operating normally within manufacturing specs at this time.
