UST Air Conditioning is the mini-split service company Honolulu 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.
Every mini-split service visit in Honolulu 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.
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 Honolulu 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.
