Came out to perform preventative maintenance on AC system. Discussed with customer about maintenance being provided, filter being changed already and any other issues she may be having with the unit. Customer stated that the system was cooling fine now that the filter was changed. I inspected the blower assembly, motor, capacitor, evaporator coil, drain and overall condition of equipment and ductwork in attic. Washed condenser coil thoroughly. Inspected the fan motor, compressor, contactor, capacitor and coil condition. Checked system operation, amps, temperatures and pressures. Unit is cooling properly within manufacturing specs at this time. Customer signed up for maintenance plan to help keep system running efficiently.
