Our AC died on a Saturday afternoon with family visiting. The dispatcher picked up on the second ring and a technician was here within a couple of hours. Bad capacitor, fixed on the spot. Cool house by dinner.
Noelani A., Royal Hawaiian EstatesDuct cleaning and sealing after our renovation. The dust problem is gone and the system is quieter. Crew was careful with the floors and furniture.
James H., Royal Hawaiian EstatesWe manage several vacation rentals and needed a company that would coordinate with guests and send invoices to us. UST has been reliable, on time and fair on price every single call.
Robert N., Royal Hawaiian EstatesMost 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.
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.
Same day for most repair calls and within hours for emergencies. Call (855) 459-5498 and the dispatcher gives you a real arrival window.
Yes. Mini-splits are our most requested installation on the Big Island because they cool individual rooms efficiently without ductwork and many models also heat.
All of them: Carrier, Trane, Lennox, Rheem, Goodman, Daikin, Mitsubishi, Fujitsu, LG, Gree, Panasonic, York, Bryant and more. Our trucks carry universal and brand-specific parts.
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.
