Lahaina Customers on Our Heater Installation

★★★★★

Heat pump stopped heating on a cold Volcano night. The technician walked me through a reset on the phone first, then came out the next day to replace the defrost board. Really appreciated not being charged for an unnecessary trip.

Pua L., Lahaina
★★★★★

Thermostat was blank and I assumed the worst. Turned out to be the float switch on a clogged drain. Quick fix, small bill, honest explanation.

Nalani B., Lahaina
★★★★★

The dehumidifier they installed ended our mold problem in the closets. Air in the house feels completely different and the AC runs less.

Furnace & Heater Installation in Lahaina: Questions We Hear Most

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.

What areas near Lahaina do you serve?

We cover all of Maui, including Kaanapali, Mahinahina, Napili-Honokowai, Launiupoko, Kapalua, Olowalu. If you are anywhere in Hawaii, call (855) 459-5498 and we will confirm availability.

Do homes in Lahaina need heating?

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.
