Responsive and polite from the first call to the final handshake. The AC not cooling problem was a frozen coil from a dirty filter and airflow issue, all sorted the same day.
Tiare V., KurtistownThermostat was blank and I assumed the worst. Turned out to be the float switch on a clogged drain. Quick fix, small bill, honest explanation.

Jason L., KurtistownSame day for most repair calls and within hours for emergencies. Call (855) 459-5498 and the dispatcher gives you a real arrival window.
Yes. UST Air Conditioning answers live 24/7 and dispatches emergency technicians throughout Kurtistown and the rest of the Big Island for no-cool, no-heat, leaks and electrical problems.
Yes. Mini-splits are our most requested installation on the Big Island because they cool individual rooms efficiently without ductwork and many models also heat.
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.
Almost always a condensate drain clogged by algae, which grows fast in Hawaii humidity. Occasionally a cracked drain pan or a frozen coil. We clear, treat and test the drain on every visit.
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.
Live dispatchers 24/7. Same-day service in most areas. Flat-rate pricing before work begins.
