Great experience with the commercial maintenance contract for our office. Quarterly visits, clear reports and no surprise breakdowns in two years.
James H., Mililani TownStraightforward pricing, showed up when they said they would, and the office followed up a week later to make sure everything was still working. That is rare these days.
Jason L., Mililani TownOur 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.
Robert N., Mililani TownA heat pump is an air conditioner that can run in reverse to heat. Same equipment, one extra valve, year-round comfort.
Short defrost cycles in cool, humid weather are normal. Solid ice that never clears means a defrost board, sensor or refrigerant problem.
Yes, especially for upcountry, Volcano and windward homes that need both cooling and occasional heat.
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.
Absolutely. We work with owners and property managers across Oahu, coordinate with guests and cleaners, and send invoices and reports directly to you.
