Honest 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.
Kalena W., KukuihaeleThe technician found that our ducts were leaking into the attic, which explained the hot back bedroom. Sealing them made a bigger difference than I expected and our bill dropped noticeably.
Tiare V., KukuihaeleThermostat was blank and I assumed the worst. Turned out to be the float switch on a clogged drain. Quick fix, small bill, honest explanation.
Chris Y., KukuihaeleMost 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.

Yes. Plan members get scheduled tune-ups, priority booking during heat waves, repair discounts and a full service history for the property.
Salt and humidity corrode electrical parts and coils, and dirty coils make the compressor overheat during the hottest weeks. A spring tune-up prevents most of these breakdowns.
If the system is under 10 years old and the repair costs less than a third of a new system, repair usually makes sense. Older R-22 systems and units with salt-damaged coils are usually better replaced.
Live dispatchers 24/7. Same-day service in most areas. Flat-rate pricing before work begins.
