I completed a diagnostic on a Payne air conditioning unit. I found the condenser fan motor failed. I quoted the the customer and they will let us know what they decide. Operational at this time.
I completed the spring tune up on a Goodman air conditioner. I visually inspected the furnace. Checked voltage and amps. I inspected the evaporator coil. I checked the temperature difference across the coil. Checked refrigerant charge, voltages and amps. I rinsed the condenser coils with water. Cycled and monitored the system. Operating normally at this time.
I completed a diagnostic on a Carrier AC unit. I found the door switch and furnace door was not making tight contact. I taped the door switch to prevent system from switching on and off. I also adjusted blower tap speed from 1470 to 1050 because it 2.5 ton system. The system is operational at this time.
I installed a Five Star "Infinity Series" 96% Variable Speed Two-Stage and a Five Star "Infinity Series" 19 SEER Variable-Speed 5 Ton Air Conditioner. System is set and customer is ready for the cooling season.
I performed a tune up on a Carrier "Infinity Series" 19 SEER Variable-Speed 3 Ton Air Conditioner. Everything checked out within specs. System is operational upon departure.
I performed a tune up on a York A/C unit. Everything checked out within specs. System is operational upon departure.
