Maui packs several climates into one island. In Maunaloa 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.

They take care of the AC at my mom's house and always call to let her know when they are on the way. That kind of respect for kupuna matters to our family.
Lehua D., MaunaloaThe 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.
Mark G., MaunaloaWe manage several vacation rentals and needed a company that would coordinate with guests and send invoices to us. UST has been reliable, on time and fair on price every single call.

Yes, especially for upcountry, Volcano and windward homes that need both cooling and occasional heat.
Absolutely. We work with owners and property managers across Maui, coordinate with guests and cleaners, and send invoices and reports directly to you.
If the system is under 10 years old and the repair costs less than a third of a new system, repair usually makes sense. Older R-22 systems and units with salt-damaged coils are usually better replaced.
Live dispatchers 24/7. Same-day service in most areas. Flat-rate pricing before work begins.
