Review by

“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

Review by

“They do my maintenance on my heating and air. They've done lots of things for me, so it's very positive. The service guy comes out on Saturday nights. I call them to set up their maintenance time and all that. They're very easy to work with. I love them. They get an A. They get A+'s down the board.”

“Knight has repaired a heating and air conditioner unit. They've put in four air conditioning units and two furnace units. They’re pretty professional. You can count on them, and when the job’s done, it’s neat, clean, and done well. I would grade my overall experience as A+. They are pretty good. I have recommended them to a friend.”

Review by
05/05/2016

“I always have a good experience with them. They've done anything from replacing the whole A/C and furnace unit or service. I like that they do what they say they’re going to do. They've always been very reasonably on time when they say they’re going to be there. They do the job, fix the problem, and they leave. They earned an A.”

Review by
05/05/2016

“They had to replace a part in the unit outside. They were out in a timely manner. The guy showed us the faulty part, so we could see that it was broken. He replaced it, and being we were seniors, provided us with a slight discount. He did a great job. I’d rate them as an A+. They did a good job, and I have no complaints.”

Review by
05/05/2016

“I definitely had a positive experience with them—I’m very satisfied. They did heating and air conditioner work. They put in a new furnace and air conditioning unit. They were very knowledgeable and customer savvy. They did good work, and they cleaned up well. They are just a good group of guys. They get an A from me.”

Review by
05/05/2016

“We’ve had Knight for years. We have the contract, and they check our air conditioner in the spring and our heater in the fall. Any other time we have a problem—they come out, and they do a good job. They’re all nice and friendly. They do good work, and we’ve been with them so long we can depend on them. We also bought our air conditioner from them. I would rate the overall experience as an A+.”

Review by
05/05/2016

“They've done a couple of things. They do our service on our heating and air conditioning system. We just recently bought a couple of new ones, and they installed those the last year. They are very straightforward and honest, they do a good job on their service, and they follow up and stand behind their work. They just generally, all around, do a good job. Overall, I would give Knight an A.”

Review by
05/05/2016

“I am very pleased with Knight. I’ve never had any complaints. My family has been using them, and my parents used them. I’m 8 years old. They do everything that I need them to do with heating and air. They have done it 1% plus. I love everything about them. There is nothing whatsoever that I could say to complain about their work. I would rate my overall experience with them an A+.”

Review by
05/05/2016

“They did a good job. They came out and did the air conditioning service—my seasonal maintenance for the beginning of the air conditioning season. Actually, they were on time—they were here when they said they were going to be here. They did what they needed to do, everything worked fine, and it was just really easy. I’d give Knight an A+ rating. I have already recommended them.”

Review by
05/05/2016

“I always have a good experience with them. I’ve had them for years. They look after my air conditioner and my furnace. They put in a new one for me. I have the maintenance twice a year, and if something goes wrong, I call them and they come out and take care of it. All the young men that come are very nice, polite, and very businesslike. They are people you don’t mind letting come into your home. It was A+. I have recommended them before.”

Review by
05/05/2016

“Knight does all of my HVAC work. They do our service maintenance in the fall and spring to make sure everything is up and running. If it’s low on Freon, they fill it. We did have a complete air conditioning unit replaced over the summer, and they put that in. It’s pretty easy to get in touch with someone when you call. You usually get to talk to a person during business hours when you call. If they know who you need to transfer to, they transfer you. If you make an appointment, it’s usually within a week or as soon as they can get out there. So you're not having to wait on someone to get out there if you have air conditioning not working upstairs where all your people are sleeping. They have fast, prompt service, and they get there when they say they’re going to get there. They are reliable. I’d give them an A.”

Review by
05/05/2016

“They've done work several times for me, and they put in a whole new air conditioner system. They maintain it. I have a service contract with them, and they come twice a year and service it. Also, they take care of the air conditioner where I work. One of the companies right across from me had them there Monday for service. I love that they’re punctual. They come when they say they’re going to and very seldom do they not have parts they need—which I think is great because it doesn’t put you off. I just think they’re very well prepared. I’d give them A+ overall. I recommend them all the time.”

Review by
05/05/2016

“We have a maintenance contract with Knight, so they just check our heating at the beginning of fall and our air conditioning in the spring. I really like the people that have come. First of all, they are prompt, and I like that. If you tell me you’re going to be there at a certain time, be there at a certain time. They are always very considerate about not tracking in the house and watching not to mess up anything. Just overall, I like the people that have done the work, and as far as I know they do a good job. They do what they’re supposed to do. It was A+.”

Review by
05/05/2016

“I had a lightning strike and they put a new air conditioning system in. There were a couple of issues, but they came right out and fixed it. The warranty is good, and their service is good. There is nothing to dislike, so I guess it’s all positive. They seem to care, and they do a good job. I’ve got a service contract with them. They come out twice a year to service the equipment. The problem was with the equipment, Trane equipment. I would rate the overall experience as an A. I have recommended them to several friends.”

Review by
05/05/2016

Review by

Review by

Review by

“They put in two units in my house—heating and air. They also do a yearly inspection of the furnace. I think they’re honest and they always do a good job. I would grade the overall experience as A+.”

Review by
05/05/2016

“I’m always happy with them. We have a maintenance agreement with them, so they come every six months and check the system. They’re prompt, the customer service is great, and they’re always professional. I would say the overall experience was A.”

Review by

Review by

“Last year they had to replace a compressor for me on the air conditioner, and after that it has been primarily maintenance. They are reliable and courteous. They are just good people. I would rate Knight the highest they can be rated— A+.”

Review by
05/05/2016

“The two technicians they sent out did a great job with the install. I had the air conditioner unit and heater replaced. I liked the price. They were very professional, and they were on time. They did a really good job on the install. I’d grade the overall experience as an A+.”

Review by
05/05/2016

Review by
05/05/2016

“They are really great. They are super nice and easy to work with. They put in my HVAC system last year, and then they came and replaced the air filter for me in January. They are replacing another one in July, I think. I would grade the overall experience as A+.”

Review by
05/05/2016

“They do the maintenance on my furnace and air conditioning. I’ve had them for years, and they seem to know what they’re doing. They are always on time and professional. I would rate the overall experience as an A. Everything seems to work, so it’s done well.”

Review by
05/05/2016

“It was moderately positive because it took two trips for the guy to fix the problem. They fixed it the first time, and then the furnace stopped working. Then they came back the second time with the part. I would say my experience was neutral to negative. This was a one-time deal. The furnace is only a year old, and the part was broken and needed to be replaced. They did not install the furnace, but the company that did it, the fellow retired and sold it somebody else. I didn’t feel comfortable having him so I figured I’d give Knight a try. I’d probably grade the overall experience as a B. I would give them an A for customer service because they showed up right after I called them.”

Review by
08/11/2015

“Knight Air Conditioning & Heating inspected our two HVAC units in a home we use as a rental house in Georgia. They found a couple of parts that needed to be replaced. They talked to us up front about what it would cost and let us make the decision of when to replace it or not, which we did. They were very professional the whole time they were there. They did a good job. I first heard of them through our real estate agent. She knew of them and gave us their name and contact information. They’re an A-grade service.”

Review by
08/11/2015

“The technicians from Knight Air Conditioning & Heating do a good job. I've been doing business with them for a long time, and I'm really satisfied with the service they provide. I've got an annual service agreement with them. When I recently had a problem with my system, I called and reported the problem, and they sent a technician out right away. They've exceeded their service level guarantee on my annual service agreement. I've lived in the area for 22 years, and I've been doing business with them probably about that long. They’ll always have an A in my book.”

Review by
08/11/2015

“Joel is the guy that came out here. I think he's one of the top engineers. It went pretty well. Knight Air Conditioning & Heating installed an air conditioning unit in my basement. It's been quite problematic with humidity. Four different contractors bid on it. It turns out Knight Air Conditioning & Heating was the most expensive one, but they were the most competent one to take care of my humidity problem. It worked out pretty well, so it was money well spent. I'd give them the highest grade possible: A+.”

Review by
08/11/2015

“They do work for me all the time. They put in a new heating and air system for me in my home. They took out all the ductwork and put in new ductwork. It was wonderful. Then, when I moved to my new home two years ago, the HVAC system was horrible. I called them and said, 'Can you come and take it out and put in new?' They did that for me. They help me any time I ever need anything. I have a maintenance policy with them where they come twice a year and keep us all updated on everything. They're wonderful. I'd give them an A.”
