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.
Robert N., LaupahoehoeHonest 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., LaupahoehoeWe had guests checking in and no AC. They treated it as the emergency it was and had the unit running two hours before check-in.
Jennifer C., LaupahoehoeYes. Plan members get scheduled tune-ups, priority booking during heat waves, repair discounts and a full service history for the property.
Same day for most repair calls and within hours for emergencies. Call (855) 459-5498 and the dispatcher gives you a real arrival window.
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.
Almost always a condensate drain clogged by algae, which grows fast in Hawaii humidity. Occasionally a cracked drain pan or a frozen coil. We clear, treat and test the drain on every visit.
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.
Absolutely. We work with owners and property managers across the Big Island, coordinate with guests and cleaners, and send invoices and reports directly to you.
Live dispatchers 24/7. Same-day service in most areas. Flat-rate pricing before work begins.
