Oahu's leeward side bakes from May through October, and the trade winds that keep Honolulu 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.

Our 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.
David W., HonoluluNew heat pump installed for our upcountry home. It cools in the afternoon and heats on the cold nights, and our electric bill is lower than with the old space heaters.
Jason L., HonoluluOur AC died on a Saturday afternoon with family visiting. The dispatcher picked up on the second ring and a technician was here within a couple of hours. Bad capacitor, fixed on the spot. Cool house by dinner.
Ryan I., HonoluluOversized systems cool quickly without running long enough to remove moisture. A dehumidifier or correctly sized system fixes it.
High-MERV or HEPA filtration captures fine particulates; sealing the home and running the system in recirculate mode helps on heavy vog days.
Keep humidity under 55 percent, clean the coil and drain annually and consider a UV coil light.
