UST Air Conditioning is the AC refrigerant recharge company Waipio 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.
We schedule AC refrigerant recharge in Waipio around your life, with morning, afternoon and evening windows, text updates when the technician is on the way and 24/7 emergency dispatch for the calls that cannot wait.
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.
Oahu's leeward side bakes from May through October, and the trade winds that keep Waipio 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.
