Maui packs several climates into one island. In Kualapuu you may be cooling against Kihei-style sun and humidity or heating on a 45-degree Kula night, sometimes in the same week. Heat pumps and mini-splits that do both are the systems we install and repair most.

Called three companies for an installation quote. UST was not the cheapest but they were the only ones who measured the house and did a load calculation. The system is perfectly sized.
Steven K., KualapuuThe compressor was covered under warranty and UST handled the paperwork with the manufacturer. We only paid for labor and refrigerant. Would not have known to ask.
Chris Y., KualapuuHonest people. I was told by another company I needed a new system. UST found a refrigerant leak at a fitting, fixed it and charged the system properly. That was two summers ago and it still runs great.
Jennifer C., KualapuuNine times out of ten it is low refrigerant from a leak, a failed capacitor keeping the compressor from starting, or airflow so restricted the coil freezes. All three are diagnosed on the first visit.
Refrigerant does not get used up; if it is low there is a leak. Topping off without a repair means paying again next month and risking the compressor.
Turn the system to off (not cool) so a frozen coil can thaw, close blinds on the sunny side and run ceiling fans.
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.
Absolutely. We work with owners and property managers across Maui, coordinate with guests and cleaners, and send invoices and reports directly to you.
