Hawaii is hard on heating and cooling equipment. Salt-laden trade winds corrode coils and electrical connections, year-round humidity clogs drains and feeds mold, and vog on the Big Island loads filters and coils with fine particulate. Every heater installation call we run accounts for those conditions, with corrosion-resistant parts and a written report of what we found.

Our 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.

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.

We had a salt-corroded outdoor unit that finally gave out. UST replaced it with a coated-coil model and explained how to hose it down monthly. Wish we had called them years ago.

Furnace & Heater Installation FAQ

What is the most efficient heating for Hawaii?

An inverter heat pump or ductless mini-split. It provides heat at a fraction of the cost of electric resistance strips and cools in summer.

How long does installation take?

Most furnace or air-handler replacements are completed in one day.

Can you add heat to my existing AC?

Often yes, either by adding heat strips to the air handler or swapping the outdoor unit for a heat pump.
