Indoor Air Quality in Hawaiian Ocean ViewThe Big Island asks more of a heating and cooling system than any other island. Hawaiian Ocean View 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.
Honest 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.
Brandon T., Hawaiian Ocean ViewThe dehumidifier they installed ended our mold problem in the closets. Air in the house feels completely different and the AC runs less.
Tiare V., Hawaiian Ocean ViewOur condo building has strict access rules and they handled everything with the resident manager. New air handler installed in a day with no drama.
Kalena W., Hawaiian Ocean ViewYes. Mini-splits are our most requested installation on the Big Island because they cool individual rooms efficiently without ductwork and many models also heat.
Some do, especially at elevation and on windward slopes where winter nights drop into the 50s. Heat pumps and mini-splits in heat mode are the most efficient way to add 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.
Most common repairs, such as capacitors, contactors, drain clearing and fan motors, fall in a modest flat-rate range that we quote before starting. Larger repairs like compressors or coils are priced against replacement so you can decide. There are no hidden fees.
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.
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.
Live dispatchers 24/7. Same-day service in most areas. Flat-rate pricing before work begins.
