Trade-wind salt on the north shore, relentless sun on the leeward side and chilly upcountry evenings: Waihee-Waiehu equipment sees all of it. Our tune-ups focus on the coil corrosion, drain clogs and refrigerant leaks that Maui conditions cause.
The mini-split in our bedroom kept dripping down the wall. Two other companies never called back. UST came the next morning, cleared the drain, cleaned the coil and showed me photos of the mold they removed.
Brandon T., Waihee-WaiehuThe compressor was covered under warranty and UST handled the paperwork with the manufacturer. We only paid for labor and refrigerant. Would not have known to ask.
Tiare V., Waihee-WaiehuI called at 10 pm because the unit was making a horrible grinding noise. They were here by 7 the next morning and the fan motor was replaced before lunch. Great communication the whole time.

Dead batteries, a tripped float switch on the drain line, or a blown low-voltage fuse. All are quick fixes.
Yes, with schedules and remote control you avoid cooling an empty home, which adds up in Hawaii's electric rates.
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.
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.
