I completed the spring tune up on a Carrier 13 SEER 3.5 Ton 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.
