Indoor Air Quality in Kaneohe StationOahu's leeward side bakes from May through October, and the trade winds that keep Kaneohe Station 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 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.
Noelani A., Kaneohe StationI called at 10 pm because the unit was making a horrible grinding noise. They were here by 7 the next morning and the fan motor was replaced before lunch. Great communication the whole time.
Keola M., Kaneohe StationOur restaurant's rooftop unit failed on a Friday. They came that evening, got us cooling again with a temporary fix and replaced the compressor the following week around our hours.
Kiana P., Kaneohe StationWe cover all of Oahu, including Kaneohe, Heeia, Kailua, Ahuimanu, Kahaluu, Maunawili. If you are anywhere in Hawaii, call (855) 459-5498 and we will confirm availability.
Almost always a condensate drain clogged by algae, which grows fast in Hawaii humidity. Occasionally a cracked drain pan or a frozen coil. We clear, treat and test the drain on every visit.
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.
Same day for most repair calls and within hours for emergencies. Call (855) 459-5498 and the dispatcher gives you a real arrival window.
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.
