UST Air Conditioning is the residential HVAC repair company Maunawili residents call first. Our technicians arrive the same day in most cases, diagnose the real problem and complete most residential HVAC repair jobs on the first visit.
We schedule residential HVAC repair in Maunawili around your life, with morning, afternoon and evening windows, text updates when the technician is on the way and 24/7 emergency dispatch for the calls that cannot wait.
Every residential HVAC repair visit in Maunawili 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.
Oahu's leeward side bakes from May through October, and the trade winds that keep Maunawili 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.
Mark G., MaunawiliFast, professional and no upselling. The tune-up was thorough and they caught a failing contactor before it left us without AC in August.
Momi E., MaunawiliWe 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.
Jennifer C., MaunawiliYes, including buildings with strict access rules. We coordinate with your resident manager.
Absolutely. We invoice and report to managers for rentals and multi-unit owners.
We service window and through-wall units; portable units are usually more economical to replace.
