The Big Island asks more of a heating and cooling system than any other island. Captain Cook homes deal with humidity and salt near the coast, vog drifting from Kilauea, and cool nights at elevation where a heat pump earns its keep. We size and service equipment for that range.

The 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.
Lehua D., Captain CookFast, professional and no upselling. The tune-up was thorough and they caught a failing contactor before it left us without AC in August.
Michael S., Captain CookWe 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.
Kalena W., Captain CookThe nameplate lists the factory charge; line length changes it. We weigh the charge in and verify it by pressures and temperatures rather than guessing.
It is no longer produced and is expensive. For older R-22 systems we often recommend budgeting for replacement rather than repeated recharges.
Systems are sealed; loss means a leak, most often at the evaporator coil, a fitting or a corroded line set near the ocean.
Salt and humidity corrode electrical parts and coils, and dirty coils make the compressor overheat during the hottest weeks. A spring tune-up prevents most of these breakdowns.
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.
