Indoor Air Quality in HalaulaThe Big Island asks more of a heating and cooling system than any other island. Halaula homes deal with humidity and salt near the coast, vog drifting from Kilauea, and cool nights at elevation where a heat pump earns its keep. We size and service equipment for that range.
Our AC died on a Saturday afternoon with family visiting. The dispatcher picked up on the second ring and a technician was here within a couple of hours. Bad capacitor, fixed on the spot. Cool house by dinner.
Steven K., HalaulaThe dehumidifier they installed ended our mold problem in the closets. Air in the house feels completely different and the AC runs less.
Keola M., HalaulaFast, professional and no upselling. The tune-up was thorough and they caught a failing contactor before it left us without AC in August.
Tiare V., HalaulaYes. UST Air Conditioning answers live 24/7 and dispatches emergency technicians throughout Halaula and the rest of the Big Island for no-cool, no-heat, leaks and electrical problems.
Yes. Plan members get scheduled tune-ups, priority booking during heat waves, repair discounts and a full service history for the property.
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.
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.
Absolutely. We work with owners and property managers across the Big Island, coordinate with guests and cleaners, and send invoices and reports directly to you.
Salt and humidity corrode electrical parts and coils, and dirty coils make the compressor overheat during the hottest weeks. A spring tune-up prevents most of these breakdowns.
Live dispatchers 24/7. Same-day service in most areas. Flat-rate pricing before work begins.
