Poipu Customers on Our AC Not Cooling Repair

★★★★★

Great experience with the commercial maintenance contract for our office. Quarterly visits, clear reports and no surprise breakdowns in two years.

Kawika O., Poipu
★★★★★

Very thorough. The technician explained what he was checking at each step and left a written report with photos. Signed up for the maintenance plan on the spot.

Tiare V., Poipu
★★★★★

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 Poipu: 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.

Do homes in Poipu need heating?

Some do, especially at elevation and on windward slopes where winter nights drop into the 50s. Heat pumps and mini-splits in heat mode are the most efficient way to add heat.

Do you install ductless mini-splits in Poipu?

Yes. Mini-splits are our most requested installation on Kauai because they cool individual rooms efficiently without ductwork and many models also heat.
