UST Air Conditioning is the AC refrigerant recharge company Black Sands residents call first. Our technicians arrive the same day in most cases, diagnose the real problem and complete most AC refrigerant recharge jobs on the first visit.
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 AC refrigerant recharge appointment with whoever needs to be involved and leaves the space clean.
Because we work in Black Sands every week, our technicians know the equipment common to the Big Island 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.
The Big Island asks more of a heating and cooling system than any other island. Black Sands 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.
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.
Momi E., Black SandsCalled three companies for an installation quote. UST was not the cheapest but they were the only ones who measured the house and did a load calculation. The system is perfectly sized.
Jennifer C., Black SandsOur 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.
Jennifer C., Black SandsThe nameplate lists the factory charge; line length changes it. We weigh the charge in and verify it by pressures and temperatures rather than guessing.
It is no longer produced and is expensive. For older R-22 systems we often recommend budgeting for replacement rather than repeated recharges.
Systems are sealed; loss means a leak, most often at the evaporator coil, a fitting or a corroded line set near the ocean.
Almost always a condensate drain clogged by algae, which grows fast in Hawaii humidity. Occasionally a cracked drain pan or a frozen coil. We clear, treat and test the drain on every visit.
