“I want to thank and compliment Chris Waddell for coming to check my AC that had stopped cooling on one of the hottest days we've had recently. It was after hours, and he still had 2 more appointments, so he said he would not be able to make it to my house. In spite of this, he told me that if, by chance, he finished early, he would try to come. About an hour later he called me back to tell me he was on his way even though he was not that close to my house. Chris could not have been nicer or more professional, but fortunately for me, by the time he arrived, my AC had just started working again. Even though he had gone out of his way, and the AC started working on its own, Chris could not have been nicer about the situation. Thanks, Chris! I really appreciate your kindness and dedication.“

“New central air, a fiasco of wiring figured out, plus new 200 amp service along with a large handful of new outlets installed. And they still stayed late to squeeze in some additional needs - a gas line and a sink drain updated. They were at our house for 2 days, one of which ended up being 12 hours. From the first appt to completion, they came through 10,000%.“

“My mother is 85 yrs old, her furnace quit working on 1/23 first thing that morning. I called several companies and no one could come out for days. I called Best and told them the situation, they came out a few hours later and got it up and running. Riley was very professional and took care of the problem in no time. We were very pleased with the service.“

“Same day replacement for a water heater. They waste no time and do a great job. No hidden fees. The techs explained everything and answered my questions.“
