Need AC refrigerant recharge in Ko Olina? UST Air Conditioning provides fast, affordable AC refrigerant recharge to homeowners and businesses in Ko Olina and across Oahu, with 24/7 emergency response and up-front flat-rate pricing.
Because we work in Ko Olina 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.
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 AC refrigerant recharge 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 Ko Olina 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.
Very thorough. The technician explained what he was checking at each step and left a written report with photos. Signed up for the maintenance plan on the spot.
Chris Y., Ko OlinaWe 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.
Jennifer C., Ko OlinaThermostat was blank and I assumed the worst. Turned out to be the float switch on a clogged drain. Quick fix, small bill, honest explanation.
Keola M., Ko OlinaThe nameplate lists the factory charge; line length changes it. We weigh the charge in and verify it by pressures and temperatures rather than guessing.
It is no longer produced and is expensive. For older R-22 systems we often recommend budgeting for replacement rather than repeated recharges.
Systems are sealed; loss means a leak, most often at the evaporator coil, a fitting or a corroded line set near the ocean.
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.
We cover all of Oahu, including Kapolei, Makakilo, East Kapolei, Kalaeloa, Ewa Villages, Nanakuli. If you are anywhere in Hawaii, call (855) 459-5498 and we will confirm availability.
Live dispatchers 24/7. Same-day service in most areas. Flat-rate pricing before work begins.
