Indoor Air Quality in HaenaKauai is the wettest and among the saltiest of the islands. Around Haena, humidity keeps coils wet, drains clog with algae and outdoor units corrode faster than the manufacturer ever planned. We wash, coat and protect equipment with that in mind.
Very thorough. The technician explained what he was checking at each step and left a written report with photos. Signed up for the maintenance plan on the spot.
Brandon T., HaenaThe dehumidifier they installed ended our mold problem in the closets. Air in the house feels completely different and the AC runs less.
Jason L., HaenaWe 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.
Lehua D., HaenaAll 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.
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.
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.
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.
Yes. Plan members get scheduled tune-ups, priority booking during heat waves, repair discounts and a full service history for the property.
