UST Air Conditioning is the HVAC repair company Kapaa residents call first. Our technicians arrive the same day in most cases, diagnose the real problem and complete most HVAC repair jobs on the first visit.
Because we work in Kapaa every week, our technicians know the equipment common to Kauai 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.
Every HVAC repair visit in Kapaa starts with a full diagnostic and a written, flat-rate quote. You approve the price before any work begins, and if the numbers point toward replacement instead of repair we will show you both so the decision is yours.
Constant moisture and salt-laden trade winds make Kapaa one of the most demanding places in the state to keep an air conditioner alive. Regular coil cleaning, drain treatment and corrosion protection are the difference between a 7-year system and a 15-year one.
