“I've had them for years. They're great—they're honest, and I think they're reasonable. I had an incident where I wanted my duct work clean, and one of those things that comes in the mail—those coupons. I called another one of those companies, and they came. I couldn't get them out of my house because they insisted that I needed this-and-that-and-the-other; there was mildew in my ducts and they went on-and-on. They wouldn't take cash; they wanted my charge account. They were going to take it outside and do it in the machine, and I said no way. Finally got rid of them, and interestingly enough, Knight came the next day for my checkup. This other company had disconnected something, and had I turned on the heat, we would have all died. Knight took pictures of the duct work, and there was no mildew anywhere. I was afraid to report them because they knew where I lived, so I did not report them. I love Knight. They're wonderful, and they're reliable, and they're honest. They get an A+.”

Review by
05/11/2017

“I've been dealing with them for nearly 40 years, and I've never had one instance of anybody complaining—or having to call somebody back because of sloppy work, or anything like that. I've had new equipment put in; I've had replacement equipment put in, and I've had it serviced every year. It sounds like I own a piece of the company—I don't, but it just happens they're nice people to deal with. I'd give them an A+.”

Review by
05/11/2017

“I've been using them for years, and I'm very happy with them. They're very reliable; they seem to have people who know what they're doing with air conditioning systems. I would give them an A+—I have recommended them and have no qualms about that.”

Review by
05/11/2017

“We've had a very positive experience with them for very many years. They're dependable, they do a good job, and they're clean. They cleaned up when they left, and I felt like they were reasonable and very honest. I'd grade them A+ down the board.”

Review by
05/11/2017

“They've been doing it for several years, and they do fine. They've been doing my air conditioning for about 12 years now. I just like them; they do good work. I'd give them an A.”

Review by

“They're just very honest and professional, and the people are good from their repair department. I chose them because they were in the blue book, Best Pick Reports. They're A+.”

Review by
