“5 ⭐⭐⭐⭐⭐One Hour lived up to their name with call back, same day service call and installation of replacement blower motor the next day. From Wendy's response, and Trent's assessment of the problem, Dustin was able to complete the repair without any complications. They used phone and text to make things simple for all.”

“Of course my heat would go out on one of the coldest days! And on a weekend! But Roman was here within an hour, had it diagnosed and up in running quickly. Roman was very knowledgeable and explained everything fully. Although I will need additional repair in the coming days, Roman was sensitive to my need for heat and now we are toasty.”
