Heat pump stopped heating on a cold Volcano night. The technician walked me through a reset on the phone first, then came out the next day to replace the defrost board. Really appreciated not being charged for an unnecessary trip.
James H., LahainaWe 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.
Noelani A., LahainaOur 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.

Live dispatchers 24/7. Same-day service in most areas. Flat-rate pricing before work begins.
