For reliable AC refrigerant recharge in Kaunakakai, Maui homeowners trust UST Air Conditioning. We handle every brand and system type, from ductless mini-splits and heat pumps to central air and packaged units.
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.
Because we work in Kaunakakai every week, our technicians know the equipment common to Maui 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.
Trade-wind salt on the north shore, relentless sun on the leeward side and chilly upcountry evenings: Kaunakakai equipment sees all of it. Our tune-ups focus on the coil corrosion, drain clogs and refrigerant leaks that Maui conditions cause.
The dehumidifier they installed ended our mold problem in the closets. Air in the house feels completely different and the AC runs less.
Leilani K., KaunakakaiThe compressor was covered under warranty and UST handled the paperwork with the manufacturer. We only paid for labor and refrigerant. Would not have known to ask.
Ashley F., KaunakakaiThey 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.
Kiana P., KaunakakaiThe 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.
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.
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.
Live dispatchers 24/7. Same-day service in most areas. Flat-rate pricing before work begins.
