Hilo Customers on Our Mini-split Service

★★★★★

We had guests checking in and no AC. They treated it as the emergency it was and had the unit running two hours before check-in.

We manage several vacation rentals and needed a company that would coordinate with guests and send invoices to us. UST has been reliable, on time and fair on price every single call.

★★★★★

I called at 10 pm because the unit was making a horrible grinding noise. They were here by 7 the next morning and the fan motor was replaced before lunch. Great communication the whole time.
