Indoor Air Quality in West Loch EstateBetween the afternoon heat, the humidity that settles in when the trades drop, and the salt that rides in on the breeze, air conditioners around West Loch Estate 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 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.
Nalani B., West Loch EstateThey installed a multi-zone ductless system in our home and it changed our summers. The crew was tidy, explained everything and the price matched the quote to the dollar.
Jason L., West Loch EstateCalled three companies for an installation quote. UST was not the cheapest but they were the only ones who measured the house and did a load calculation. The system is perfectly sized.

Yes. Plan members get scheduled tune-ups, priority booking during heat waves, repair discounts and a full service history for the property.
Most common repairs, such as capacitors, contactors, drain clearing and fan motors, fall in a modest flat-rate range that we quote before starting. Larger repairs like compressors or coils are priced against replacement so you can decide. There are no hidden fees.
If the system is under 10 years old and the repair costs less than a third of a new system, repair usually makes sense. Older R-22 systems and units with salt-damaged coils are usually better replaced.
Yes. UST Air Conditioning answers live 24/7 and dispatches emergency technicians throughout West Loch Estate and the rest of Oahu for no-cool, no-heat, leaks and electrical problems.
Salt and humidity corrode electrical parts and coils, and dirty coils make the compressor overheat during the hottest weeks. A spring tune-up prevents most of these breakdowns.
