Kahului Customers on Our Mini-split Service

★★★★★

Very thorough. The technician explained what he was checking at each step and left a written report with photos. Signed up for the maintenance plan on the spot.

Pua L., Kahului
★★★★★

Called three companies for an installation quote. UST was not the cheapest but they were the only ones who measured the house and did a load calculation. The system is perfectly sized.

Jennifer C., Kahului
★★★★★

They installed a multi-zone ductless system in our home and it changed our summers. The crew was tidy, explained everything and the price matched the quote to the dollar.
