Need mini-split service in Heeia? UST Air Conditioning provides fast, affordable mini-split service to homeowners and businesses in Heeia and across Oahu, with 24/7 emergency response and up-front flat-rate pricing.
Every mini-split service visit in Heeia 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.
Because we work in Heeia 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.
Oahu's leeward side bakes from May through October, and the trade winds that keep Heeia 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.

Called three companies for an installation quote. UST was not the cheapest but they were the only ones who measured the house and did a load calculation. The system is perfectly sized.
Keola M., HeeiaThe technician found that our ducts were leaking into the attic, which explained the hot back bedroom. Sealing them made a bigger difference than I expected and our bill dropped noticeably.
Ryan I., HeeiaHeat pump stopped heating on a cold Volcano night. The technician walked me through a reset on the phone first, then came out the next day to replace the defrost board. Really appreciated not being charged for an unnecessary trip.
Malia R., HeeiaAll major brands including Mitsubishi, Daikin, Fujitsu, LG, Gree, Carrier and Panasonic.
Typically up to five indoor heads on a single condenser, depending on capacity. We size each head to the room.
