Need AC refrigerant recharge in Mountain View? UST Air Conditioning provides fast, affordable AC refrigerant recharge to homeowners and businesses in Mountain View and across the Big Island, with 24/7 emergency response and up-front flat-rate pricing.
Because we work in Mountain View 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. Mountain 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.
Called 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.
Robert N., Mountain ViewNew 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.
Leilani K., Mountain ViewDuct cleaning and sealing after our renovation. The dust problem is gone and the system is quieter. Crew was careful with the floors and furniture.

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.
