UST Air Conditioning is the residential HVAC repair company Mahinahina 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.
Every residential HVAC repair visit in Mahinahina 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.
Because we work in Mahinahina every week, our technicians know the equipment common to Maui 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.
Maui packs several climates into one island. In Mahinahina you may be cooling against Kihei-style sun and humidity or heating on a 45-degree Kula night, sometimes in the same week. Heat pumps and mini-splits that do both are the systems we install and repair most.

Michael S., MahinahinaHonest people. I was told by another company I needed a new system. UST found a refrigerant leak at a fitting, fixed it and charged the system properly. That was two summers ago and it still runs great.
Jason L., MahinahinaThermostat was blank and I assumed the worst. Turned out to be the float switch on a clogged drain. Quick fix, small bill, honest explanation.
Ryan I., MahinahinaYes, 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.
Most common repairs, such as capacitors, contactors, drain clearing and fan motors, fall in a modest flat-rate range that we quote before starting. Larger repairs like compressors or coils are priced against replacement so you can decide. There are no hidden fees.
Some do, especially at elevation and on windward slopes where winter nights drop into the 50s. Heat pumps and mini-splits in heat mode are the most efficient way to add heat.
Live dispatchers 24/7. Same-day service in most areas. Flat-rate pricing before work begins.
