Air conditioner maintenance. Cleaned, washed out and serviced condensing units. Changed both furnace filters that customer provided. Both units were pretty dirty with cottonwood. Tested capacitor, contactor, fan motor amperage and compressor amperage and continuity. Everything was in accurate working condition. Checked refrigerant for both units. R410a refrigerant levels were in accurate efficiency range on both units. Both units are operating and cooling as they should at this time. Customer is going to renew annual VIP maintenance program in fall.
