UST Air Conditioning is the AC refrigerant recharge company Hawaiian Acres residents call first. Our technicians arrive the same day in most cases, diagnose the real problem and complete most AC refrigerant recharge jobs on the first visit.
Because we work in Hawaiian Acres every week, our technicians know the equipment common to the Big Island 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.
Every AC refrigerant recharge visit in Hawaiian Acres 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.
From Kona-side heat to the damp, cool evenings of the Puna and Volcano districts, Hawaiian Acres homeowners need equipment that cools, dehumidifies and, some nights, heats. Salt, vog particulate and heavy rain all shorten equipment life without regular maintenance.
They take care of the AC at my mom's house and always call to let her know when they are on the way. That kind of respect for kupuna matters to our family.
Robert N., Hawaiian AcresWe had guests checking in and no AC. They treated it as the emergency it was and had the unit running two hours before check-in.
David W., Hawaiian AcresVery 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.
Leilani K., Hawaiian AcresThe 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.
Yes. Mini-splits are our most requested installation on the Big Island because they cool individual rooms efficiently without ductwork and many models also heat.
Live dispatchers 24/7. Same-day service in most areas. Flat-rate pricing before work begins.
