UST Air Conditioning is the mini-split service company Kailua 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.
Every mini-split service visit in Kailua starts with a full diagnostic and a written, flat-rate quote. You approve the price before any work begins, and if the numbers point toward replacement instead of repair we will show you both so the decision is yours.
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.
Oahu's leeward side bakes from May through October, and the trade winds that keep Kailua bearable also carry salt straight into outdoor condenser coils. Systems here work hard almost every day of the year, which is why we see so many worn capacitors, corroded contactors and refrigerant leaks at brazed joints.
Call (855) 459-5498 now for mini-split service in Kailua. We answer 24/7.
We had a salt-corroded outdoor unit that finally gave out. UST replaced it with a coated-coil model and explained how to hose it down monthly. Wish we had called them years ago.
