Heating repair for heat pumps, mini-splits in heat mode, electric furnaces and wall heaters, for the cool nights that upcountry, Volcano and windward homes really do get. UST Air Conditioning provides heating 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 heating repair call we run accounts for those conditions, with corrosion-resistant parts and a written report of what we found.
The dehumidifier they installed ended our mold problem in the closets. Air in the house feels completely different and the AC runs less.
Kalena W., HawaiiWe had a salt-corroded outdoor unit that finally gave out. UST replaced it with a coated-coil model and explained how to hose it down monthly. Wish we had called them years ago.
David W., HawaiiThe compressor was covered under warranty and UST handled the paperwork with the manufacturer. We only paid for labor and refrigerant. Would not have known to ask.
Noelani A., HawaiiYes. Kula, Waimea, Volcano, Makawao and many mauka neighborhoods drop into the 40s and 50s in winter. Heat pumps and mini-splits in heat mode are the usual solution.
It may be in defrost mode, low on refrigerant, or the reversing valve may be stuck. A technician can tell in minutes.
