I completed spring tune up on a Carrier air conditioner. I visually inspected the furnace. I inspected the evaporator coil. I checked the temperature difference across the coil. Checked voltage and amps. Inspected heat pump. Checked refrigerant charge, voltages and amps. Added 1.5LBS of 410-A. I rinsed the condenser coils with water. Cycled and monitored the system. Operating normally at this time.
