Kawika O., Eden RocSome 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.
Yes. Plan members get scheduled tune-ups, priority booking during heat waves, repair discounts and a full service history for the property.
Absolutely. We work with owners and property managers across the Big Island, coordinate with guests and cleaners, and send invoices and reports directly to you.
Most common repairs, such as capacitors, contactors, drain clearing and fan motors, fall in a modest flat-rate range that we quote before starting. Larger repairs like compressors or coils are priced against replacement so you can decide. There are no hidden fees.
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.
Live dispatchers 24/7. Same-day service in most areas. Flat-rate pricing before work begins.
