We didn't know who to call to get our AC checked out, and were afraid we would have to pay a fortune to get someone out to look at it during the hottest time of the summer. A neighbor recommended ROX heating and Air.I emailed to set up an appt, and had a call from Jason right away. He was out within an hour, had the part he needed, and repair was done in no time. The cost was super reasonable, and Jason was a pleasure to work with.

When our office water heater went out and our office was flooding. Jason was here within the 1 hour and had the heater replaced by midday. Professional, clean, prompt and very pleasant to work with. I would highly recommend them to anyone!
