UST Air Conditioning is the HVAC installation company Makakilo residents call first. Our technicians arrive the same day in most cases, diagnose the real problem and complete most HVAC installation jobs on the first visit.
Every HVAC installation visit in Makakilo 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 installation appointment with whoever needs to be involved and leaves the space clean.
Oahu's leeward side bakes from May through October, and the trade winds that keep Makakilo bearable also carry salt straight into outdoor condenser coils. Systems here work hard almost every day of the year, which is why we see so many worn capacitors, corroded contactors and refrigerant leaks at brazed joints.

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.

Yes. Mini-splits are our most requested installation on Oahu because they cool individual rooms efficiently without ductwork and many models also heat.
Some do, especially at elevation and on windward slopes where winter nights drop into the 50s. Heat pumps and mini-splits in heat mode are the most efficient way to add heat.
