Heat pumps are the ideal Hawaii system: efficient cooling all year and heat when you need it. We repair, maintain and install all major brands. UST Air Conditioning provides heat pump repair throughout Oahu, Maui, Kauai and the Big Island with same-day appointments and 24/7 emergency dispatch.
Hawaii is hard on heating and cooling equipment. Salt-laden trade winds corrode coils and electrical connections, year-round humidity clogs drains and feeds mold, and vog on the Big Island loads filters and coils with fine particulate. Every heat pump repair call we run accounts for those conditions, with corrosion-resistant parts and a written report of what we found.
Thermostat was blank and I assumed the worst. Turned out to be the float switch on a clogged drain. Quick fix, small bill, honest explanation.
Steven K., HawaiiOur 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.
Kalena W., HawaiiI called at 10 pm because the unit was making a horrible grinding noise. They were here by 7 the next morning and the fan motor was replaced before lunch. Great communication the whole time.
Kawika O., HawaiiA heat pump is an air conditioner that can run in reverse to heat. Same equipment, one extra valve, year-round comfort.
Short defrost cycles in cool, humid weather are normal. Solid ice that never clears means a defrost board, sensor or refrigerant problem.
Yes, especially for upcountry, Volcano and windward homes that need both cooling and occasional heat.
