Wailuku Customers on Our AC Installation

★★★★★

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.

Momi E., Wailuku
★★★★★

The mini-split in our bedroom kept dripping down the wall. Two other companies never called back. UST came the next morning, cleared the drain, cleaned the coil and showed me photos of the mold they removed.

Ryan I., Wailuku
★★★★★

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

Air Conditioning Installation & Replacement in Wailuku: Questions We Hear Most

How long does a new AC installation take?

A single-zone mini-split is usually done in a day. A full central system with duct modifications typically takes one to two days.

What size air conditioner do I need?

It depends on square footage, insulation, window exposure and how much sun and humidity the home takes on. We measure instead of guessing, because an oversized unit short cycles and leaves the air clammy.

Do you offer financing on new systems?

Yes, we work with financing partners so a new system can be paid monthly. Ask your comfort advisor for current options.

Do you offer maintenance plans in Wailuku?

Yes. Plan members get scheduled tune-ups, priority booking during heat waves, repair discounts and a full service history for the property.

How quickly can a technician get to Wailuku?

Same day for most repair calls and within hours for emergencies. Call (855) 459-5498 and the dispatcher gives you a real arrival window.
