Because we work in Hilo every week, our technicians know the equipment common to the Big Island homes, the corrosion the trade winds cause and the parts that fail first. That local experience means faster diagnosis, fewer return trips and repairs that last.

From Kona-side heat to the damp, cool evenings of the Puna and Volcano districts, Hilo homeowners need equipment that cools, dehumidifies and, some nights, heats. Salt, vog particulate and heavy rain all shorten equipment life without regular maintenance.

Hilo Customers on Our Thermostat Service

★★★★★

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.

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.

The 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.

Thermostat Installation & Repair in Hilo: Questions We Hear Most

Will a smart thermostat work with my mini-split?

Some mini-splits need a brand adapter or a smart controller. We will confirm compatibility before installing.

Why is my thermostat blank?

Dead batteries, a tripped float switch on the drain line, or a blown low-voltage fuse. All are quick fixes.

Can a thermostat save money?

Yes, with schedules and remote control you avoid cooling an empty home, which adds up in Hawaii's electric rates.

Should I repair or replace my air conditioner in Hilo?

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.

How quickly can a technician get to Hilo?

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