Waimalu Customers on Our AC Not Cooling Repair

★★★★★

Honest people. I was told by another company I needed a new system. UST found a refrigerant leak at a fitting, fixed it and charged the system properly. That was two summers ago and it still runs great.

Ryan I., Waimalu

Heat pump stopped heating on a cold Volcano night. The technician walked me through a reset on the phone first, then came out the next day to replace the defrost board. Really appreciated not being charged for an unnecessary trip.

Keola M., Waimalu
★★★★★

The mini-split in our bedroom kept dripping down the wall. Two other companies never called back. UST came the next morning, cleared the drain, cleaned the coil and showed me photos of the mold they removed.

AC Not Cooling / Not Blowing Cold Air in Waimalu: Questions We Hear Most

Why is my AC running but not cooling?

Nine times out of ten it is low refrigerant from a leak, a failed capacitor keeping the compressor from starting, or airflow so restricted the coil freezes. All three are diagnosed on the first visit.

Can I just add Freon?

Refrigerant does not get used up; if it is low there is a leak. Topping off without a repair means paying again next month and risking the compressor.

What should I do while I wait for the technician?

Turn the system to off (not cool) so a frozen coil can thaw, close blinds on the sunny side and run ceiling fans.

Which air conditioner brands do you repair in Waimalu?

All of them: Carrier, Trane, Lennox, Rheem, Goodman, Daikin, Mitsubishi, Fujitsu, LG, Gree, Panasonic, York, Bryant and more. Our trucks carry universal and brand-specific parts.

Should I repair or replace my air conditioner in Waimalu?

If the system is under 10 years old and the repair costs less than a third of a new system, repair usually makes sense. Older R-22 systems and units with salt-damaged coils are usually better replaced.
