Repair of whole-home ducted air conditioning systems, from the outdoor condenser to the air handler, ductwork and thermostat. UST Air Conditioning provides central air repair throughout Oahu, Maui, Kauai and the Big Island with same-day appointments and 24/7 emergency dispatch.
Hawaii is hard on heating and cooling equipment. Salt-laden trade winds corrode coils and electrical connections, year-round humidity clogs drains and feeds mold, and vog on the Big Island loads filters and coils with fine particulate. Every central air repair call we run accounts for those conditions, with corrosion-resistant parts and a written report of what we found.
Our restaurant's rooftop unit failed on a Friday. They came that evening, got us cooling again with a temporary fix and replaced the compressor the following week around our hours.
Nalani B., HawaiiI called at 10 pm because the unit was making a horrible grinding noise. They were here by 7 the next morning and the fan motor was replaced before lunch. Great communication the whole time.
Keola M., HawaiiThey installed a multi-zone ductless system in our home and it changed our summers. The crew was tidy, explained everything and the price matched the quote to the dollar.
Robert N., HawaiiUsually leaking or undersized ducts, closed dampers, or a dirty evaporator coil restricting airflow. A static-pressure test tells us which one.
A clogged condensate drain, a cracked drain pan or a frozen coil that is now thawing. Turn the system off to protect your ceiling and call us.
Usually 10 to 15 years, less near the ocean unless the coils are coated and maintained.
