Heating and cooling repair for single-family homes, condos, townhomes, ohana units and vacation rentals across Hawaii. UST Air Conditioning provides residential HVAC 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 residential HVAC repair call we run accounts for those conditions, with corrosion-resistant parts and a written report of what we found.
We 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.
Michael S., HawaiiVery 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.
David W., HawaiiGreat experience with the commercial maintenance contract for our office. Quarterly visits, clear reports and no surprise breakdowns in two years.
Malia R., HawaiiYes, including buildings with strict access rules. We coordinate with your resident manager.
Absolutely. We invoice and report to managers for rentals and multi-unit owners.
We service window and through-wall units; portable units are usually more economical to replace.
