UST Air Conditioning is the mini-split service company Royal Kunia 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 Royal Kunia every week, our technicians know the equipment common to Oahu 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.
We schedule mini-split service in Royal Kunia 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 Royal Kunia 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.
