UST Air Conditioning is the HVAC repair company Nanakuli residents call first. Our technicians arrive the same day in most cases, diagnose the real problem and complete most HVAC repair jobs on the first visit.
Every HVAC repair visit in Nanakuli 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 HVAC repair appointment with whoever needs to be involved and leaves the space clean.
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 Nanakuli 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.

I called at 10 pm because the unit was making a horrible grinding noise. They were here by 7 the next morning and the fan motor was replaced before lunch. Great communication the whole time.
