UST Air Conditioning is the mini-split service company Hauula 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.
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.
We schedule mini-split service in Hauula around your life, with morning, afternoon and evening windows, text updates when the technician is on the way and 24/7 emergency dispatch for the calls that cannot wait.
Between the afternoon heat, the humidity that settles in when the trades drop, and the salt that rides in on the breeze, air conditioners around Hauula live a harder life than almost anywhere on the mainland. Our technicians plan for that with coated coils, corrosion inhibitors and more frequent coil washing.

We 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.
Robert N., HauulaWe 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.
Chris Y., HauulaHonest 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.
Nalani B., HauulaAll major brands including Mitsubishi, Daikin, Fujitsu, LG, Gree, Carrier and Panasonic.
Typically up to five indoor heads on a single condenser, depending on capacity. We size each head to the room.
Mold and bacteria on the coil and blower wheel, common in Hawaii humidity. A deep clean removes it and improves airflow.
