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.
Jennifer C., Kailua-KonaHonest people. I was told by another company I needed a new system. UST found a refrigerant leak at a fitting, fixed it and charged the system properly. That was two summers ago and it still runs great.
Kiana P., Kailua-KonaThe technician found that our ducts were leaking into the attic, which explained the hot back bedroom. Sealing them made a bigger difference than I expected and our bill dropped noticeably.
