We were long-time customers of Knight having been Royal Maintenance Program subscribers for several years with our 14 year old, high efficiency furnace. From time to time they have said we needed repairs, some expensive. We paid the bills thinking the costs were legitimate. At the most recent visit (October 2020) one of their technicians came for a regular maintenance visit and said he had discovered a carbon monoxide leak and had to shut our H/Vac system down for safety reasons. He advised that our furnace was so old (14 years) that tracking down the leak would be very expensive and subsequent repairs would cost nearly as much as a new system. He recommended (several times) that their sales office contact us for a bid on a replacement furnace. I was suspicious and called another respected company in Springfield. After a lengthy inspection they said there was a small, intermittent carbon monoxide detection that seemed to be coming from an exhaust pipe with a comprised seal but they couldn't be certain that the heat exchanger wasn't leaking as well. Since that would require removing and replacing the exchanger they checked with the manufacturer and found that it had a lifetime warranty. This meant we could get a brand new exchanger for the price of the labor to install it. Final result was that it ended up costing us a few hundred dollars instead of many thousands that we would have spent on a new system if we had followed the tech's advice. This experience has made me question every service Knight ever performed for us and in the future we will be doing business elsewhere.

Very thorough inspection prior to presenting an estimate. They were in the attic to inspect the return ducting, under the house to inspect supply ducts, and everything in between. Written estimate provided several options and was very easy to read and understand. Cost of service shown here is after City Utility rebates ($950) and Federal Tax Credits ($450).

Knight sent Jeff, I believe, out to do a quote on a new furnace and AC. At that point they disconnected our old unit so we had no AC or heating. We were furious. They eventually came back a few days later with new equipment and we told them we were not happy and to please reconnect the system and we were not going to buy equipment from them after having disconnected our system without our knowledge or consent. They said no you cannot do that, you signed a contract. We had another HVAC vendor look at the contract who said no, the contract was not valid because Knight did not sign it. So we told them their contract was invalid and they finally reconnected our system begrudgingly after several phone calls complaining about the issue to Knight. They picked up their equipment. We vowed never to use them again after that experience.

According to our agent the individual arrived on time and was very pleasant to work with. I spoke with him by phone during the inspection process. He explained the problem, what needed to be done to fix it and provided a verbal rough estimate of repairs. He indicated that until initial repairs were made no further evaluation of the system could be made. We requested the seller to make the repairs so I can not comment on pricing or workmanship at this time. We will definitely call them again for routine annual service.
Description of Work: HVAC inspection as a follow on to home purchase inspection. Home inspector found HVAC system not working. Knight was hired to do a more thorough inspection, determine the issues, and provide estimate to fix.

We got bids and talked to 4 different companies. We discovered that one comparable bid was for lesser units and two were just not impressive in giving information when we asked questions. Knight had the right units at the right price and a well known Carrier brand. Their technicians were very courteous and kept everything nice and neat. The unit did have a problem about 2 weeks after installation and he was here in 45 minutes and fixed the problem quickly. Also, their annual contract for checking the units was less than some of the others.
Description of Work: We determined that we needed a new AC unit and since both units were from the original home construction, we decided to add both a new AC and a new Furnace.

There were some problems with the install. So, you might ask why I gave them the highest ratings? While it is easy to get high ratings when everything goes right, I think the real test of a company is how they handle the situation when everything doesn't go right. This company spent a tremendous amount of time and labor resources to make sure that our system was operating correctly. They were very concerned that the system be correct and that I was satisfied with their instal. In the end we got a great new system that is working perfectly. By the way, the final price was exactly the price of their bid, even though there was some equipment needed that was not in the original bid.

The service person did a great job. He responded to our after-hours call quickly, and scheduled an appointment for the following morning as we requested. He arrived on time, was very courteous, and did an excellent job. He gave us instructions on caring for our AC unit that the company that installed it had not given us.

The tech, Jared I believe, was great. He got here as close to the time I requested as he could and had it diagnosed and repaired in less than an hour. The girls in the office were great as well and they know that having no air in July is a horrible thing. Great service and great company. Will use again in the future and refer people to them as well.

It was in the 90's yesterday plus the humidity = Heat Index...Mercy, who knows? After calling and emailing "another" "A Rated" Angie's list A/C service that never answered or returned my call/email, I went back to Angie's List, to look for the next "A" Rated A/C Service - "Knight Heating and A/C Service"! I called them around 8 a.m.. and they answered! :-) A very nice lady listened to my concerns and situation. She worked me in for late morning, stated that she or someone would call before they came out. The service tech called earlier than expected, before 10 a.m.! Took him about 15 minutes to fix the problem. I am please to have a cool home again! It was 85 degrees in the house for 24 hours, before I knew something was wrong. I am VERY pleased, they responded to my call and arrived so quickly. They are friendly and professional. I certainly recommend them.

Our air conditioner died on July 2nd - just in time for the hottest day of the summer! Knight was one of three companies we had come out for estimates. We decided to go with them because of the brand they carried. We also decided to replace the furnace, as it may have been damaged when the air conditioner shorted out. Knight gave us their cell phone number so we could ask questions after hours, and we did call to ask a few more questions. As soon as we made our decision, they came out and installed the air conditioner the next day, and completed the work the following day. Really nice guys, and the office staff was great as well.

We contacted Knight Heating and Air after eight years of trying to get Goff Heating Air to get our system to work properly. We had to upgrade our unit from a 3 ton to a 5 ton. The first one was undersized for the home, by Goff, so we finally got the proper size unit but after a year of operation the coils developed a leak. We tried to get the original installer (Dale from Goff Heat & Air) to repair it and he refused so we called Knight. They showed up on time and assessed the situation. The newer 5 ton unit had not been installed properly in the house. We had to pay out of pocket to get the unit installed properly, but Knight did fix the coils under warranty. We were very pleased with their knowledge and taking the time to explain everything in detail. It was really refreshing to have someone that was not only knowledgeable but actually took the time to explain what needed to be done and why? I could not remember the exact date, but it was at the end of the summer in 2012.
Description of Work: Replaced the coils and adjusted the indoor unit to provide easier access.

Dan the owner came out last Thursday for estimate. Gave a great verbal estimate after listening to my needs. I recieved an email estimate on Monday from Chandler (owners son) with my estimate..I talked with him about several questions I had and he answered them honestly. I chose Knight for my HVAC replacement Tuesday morning. They scheduled me for Yesterday and today for replacement. The guys showed up yesterday on time and replaced the HVAC and got the AC working again. Today the are doing some duct work for me and setting up the furnace for me.. They have been great! Dan even called me last night to check on the guys to see if they were doing everything that I needed done. I can see why they have a great reputation in this area. I would highly recommend them to anyone in the future!
Description of Work: Replace HVAC, extra duct work and replace thermostat with Nest thermostat.
