UST Air Conditioning is the mini-split service company Kailua-Kona residents call first. Our technicians arrive the same day in most cases, diagnose the real problem and complete most mini-split service jobs on the first visit.
Because we work in Kailua-Kona every week, our technicians know the equipment common to the Big Island homes, the corrosion the trade winds cause and the parts that fail first. That local experience means faster diagnosis, fewer return trips and repairs that last.
Whether you are in a single-family home, a condo with strict HOA access rules or a vacation rental with guests arriving, UST Air Conditioning coordinates the mini-split service appointment with whoever needs to be involved and leaves the space clean.
From Kona-side heat to the damp, cool evenings of the Puna and Volcano districts, Kailua-Kona homeowners need equipment that cools, dehumidifies and, some nights, heats. Salt, vog particulate and heavy rain all shorten equipment life without regular maintenance.

Pua L., Kailua-KonaWe 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.
Jennifer C., Kailua-KonaHeat 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.
