Oahu AC Repair & Split AC Installation

When your AC quits on an Ewa Beach afternoon or a muggy Kaneohe night, you need someone who answers the phone and shows up. Universal Air Hawaii provides AC repair across Oahu for split AC and mini-split systems, central air, window and wall units, and condo systems.

We find the real cause — a failed capacitor, a refrigerant leak, a clogged drain, a frozen coil — and give you a flat price before any work begins. We call to confirm before we come and show you photos of what we found, so you're never guessing.

Not every repair is a big one. Many no-cooling calls come down to a dirty coil, a tripped float switch or a failed part we can replace on the spot. When the fix is bigger, we lay out repair and replacement options side by side so you can choose what makes sense for your home and budget.

Many Oahu homes were built for trade winds, with no ductwork. That's why ductless split AC is the go-to way to add cooling here. Air conditioning in Honolulu homes grew from about 14% in 1970 to about 70% by 2019. Most older homes can't take central air without major work, so mini-splits fill the gap one room — or the whole house — at a time.

Our split AC installation team sizes each room, plans clean line-set routes, handles electrical and permits when required, and works with your AOAO in condo buildings. We install efficient inverter mini-splits with new A2L refrigerants and help you claim Hawaii Energy rebates of $400 to $550 per qualifying outdoor unit, subject to program availability.

Every installation starts with a written quote that shows the equipment, the work, any rebates and the final price. We clean up completely before we leave.

Oahu is tough on air conditioners. Salt air corrodes outdoor units near the coast, Windward humidity feeds mold in split AC heads, Leeward heat pushes condensers hard and vog clogs filters island-wide. Beyond split systems, we also service central AC, window and wall units, condo systems and commercial equipment, so one call covers every system you own. Tune-ups catch small problems early, keep coils and drains clear, and help your system reach the end of its expected life instead of failing years early on a hot August afternoon. Regular split AC cleaning and maintenance keep musty smells, leaks and breakdowns away.

With Oahu electricity averaging about 43¢ per kWh, a clean, efficient system also saves real money. Our Comfort Club covers two precision tune-ups a year, priority scheduling and member savings. Whether you're in Kapolei, Mililani, Kakaako or Kailua, we serve all of Oahu. Check a price anytime with our instant estimate.
