Arrived on site to perform spring tune up on a 2018 Payne unit. Condenser is located in back yard. Furnace and Evaporator coil is located in garage. Client stated no issues. Cycled both bit and it was operational. Washed condenser coil inside and out. Found primary control good and secondary was in range. Checked start up amps and are in range but would recommend adding a compressor booster kit to help preserve compressor. Run amps are pulling 14 and max rated at 20. Refrigerant pressures are good and cooling hole at 20 degrees. Found no surge protectors on unit. Client stated he would replace filter him self and supply his own and recommend replacing every 3 months. Cycled unit and went over all findings and recommendations with client. Client is aware how unit is running and conditions and did hold off on recommendations for now. Cycled system to ensure system operating. System is operational and cooling upon departure.
