Waianae's heat, humidity and salt air are hard on equipment, which is why dependable AC refrigerant recharge matters. UST Air Conditioning brings stocked trucks and experienced technicians to every Waianae call.
Because we work in Waianae 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 AC refrigerant recharge appointment with whoever needs to be involved and leaves the space clean.
Oahu's leeward side bakes from May through October, and the trade winds that keep Waianae bearable also carry salt straight into outdoor condenser coils. Systems here work hard almost every day of the year, which is why we see so many worn capacitors, corroded contactors and refrigerant leaks at brazed joints.
New heat pump installed for our upcountry home. It cools in the afternoon and heats on the cold nights, and our electric bill is lower than with the old space heaters.
Steven K., WaianaeFast, professional and no upselling. The tune-up was thorough and they caught a failing contactor before it left us without AC in August.
Leilani K., WaianaeHeat 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.
Momi E., WaianaeThe 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.
