UST Air Conditioning is the heat pump repair company Waialua residents call first. Our technicians arrive the same day in most cases, diagnose the real problem and complete most heat pump repair jobs on the first visit.
Because we work in Waialua every week, our technicians know the equipment common to Oahu homes, the corrosion the trade winds cause and the parts that fail first. That local experience means faster diagnosis, fewer return trips and repairs that last.
Whether you are in a single-family home, a condo with strict HOA access rules or a vacation rental with guests arriving, UST Air Conditioning coordinates the heat pump repair appointment with whoever needs to be involved and leaves the space clean.
Between the afternoon heat, the humidity that settles in when the trades drop, and the salt that rides in on the breeze, air conditioners around Waialua live a harder life than almost anywhere on the mainland. Our technicians plan for that with coated coils, corrosion inhibitors and more frequent coil washing.

Heat pump stopped heating on a cold Volcano night. The technician walked me through a reset on the phone first, then came out the next day to replace the defrost board. Really appreciated not being charged for an unnecessary trip.
Noelani A., WaialuaHonest people. I was told by another company I needed a new system. UST found a refrigerant leak at a fitting, fixed it and charged the system properly. That was two summers ago and it still runs great.
Leilani K., WaialuaThermostat was blank and I assumed the worst. Turned out to be the float switch on a clogged drain. Quick fix, small bill, honest explanation.
Kiana P., WaialuaA 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.
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.
Yes. Mini-splits are our most requested installation on Oahu because they cool individual rooms efficiently without ductwork and many models also heat.
