Absolutely. We work with owners and property managers across Maui, coordinate with guests and cleaners, and send invoices and reports directly to you.
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.
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.
Some do, especially at elevation and on windward slopes where winter nights drop into the 50s. Heat pumps and mini-splits in heat mode are the most efficient way to add heat.
