Wonderful service! Showed up same day and got both units working. Signed up for their plan best we've found in the area.

I had Brandon come out and do a review of my HVAC system as it is 30 years old at this time. He was very professional and thorough in his inspection. I appreciated his being on time for the appointment and his honest comprehensive bid. I would certainly recommend using Knight Heating and Air for your A/C needs as I had several people come out and give me quotes and his was right in line with the others. read more

We had some real problems with the technician fixing my mother's heat. He come back and came back and still she was cold. Not fix in sight. He said it was wiring, so we contacted electrition, he came out, that was not it. Still bill us for the service call. I refused to pay it, and I am still getting billed. I am not one to give bad reviews, but this really was bad. I was forced to use another hvac guy, he replaced the unit and all is ok. read more

My uncle told me to use this company after his best friend recommended them. My furnace wasn't working and the air conditioner looked bad. They sent two get technicians to assess the situation and they advised me that our furnace and air conditioner were goners and they would have to be replaced. We decided to get a few quotes since this would be a large purchase. The first company came in the morning and the rep looked around inspected the old system and left. The knight was sent inspector was VERY through. He counted all our returns, double checked the ducting in the attic and educated us on systems and learned our preferences. What a difference!! Our mechanic room was not set up correctly and Ken explained how we could fix it and why some tweaks would go a LONG way. We were so thankful. Ken was amazing. The team showed up on Tuesday and they were efficient and kind. They protected our floors and worked together to get all the systems in and running smoothly. We will be telling all our friends about this group- they treat you better than family ! read more

I'm a little in writing a review. I prefer to give people the benefit of doubt. Knight installed my unit summer off 2019 did a great job of installing. Was fast to get here and get me taken care of. Summer of 2020 my unit started running water about a week out of warranty. Called and they sent out a tech, he checked my pump and blew air though my flow line and said he couldn't find anything wrong. Unit work good for a couple of weeks had tech back out (same tech) did the same thing still couldn't find what was causing it. Out of warranty so of course I was charged for two visits and unit wasn't fixed. Summer 2021 same issued, ac was cooling good so just dealt with the water running across my garage floor. Summer 2022 have a total flood going across my floor and water seeping in under my kitchen title. Spoke with a friend that works on AC's he came out and had it fixed in minutes. Apparently I was supposed to putting a little bleach in my drain pipe from my unit to my pump to keep algae from building up and blocking my line. Gave them 1 star because installation was good, follow up with issues, customer service not good. read more

Knight Heating & Air Conditioning - Water running out garage door - Heating & Air Conditioning/HVAC Near Me - Nixa, Missouri

See all

They tried to sell me a new system, saying my unit was too small for my house as that is why it was not cooling. House was built in 06, unit was new and never had issues before. Turned out to be a blockage in the line that cost me $1500 over three visits. Every time they would continue to 'find' other things that I needed to upgrade. After they cleaned the line it has worked fine since, this was in 2014. I would not recommend this company to anyone. read more

At 9:30 tonight I realized that my ac was not working properly. I called knight shortly after and they were at my house in record time. The rep was very knowledgeable and friendly. It is now 11:10. The rep just left my house and it is in its way to being cool again. I will definitely use them again for my heating/cooling needs. He came from Nixa, I live in Buffalo. After hours prices were a hit to my budget but the service was top notch. read more

Our A/C went out on a Thursday night and I called it in to Knight the next morning when they opened. The gal who answered the phone said they were a week out for work orders! In 95 degree heat with humidity, I was not happy. So before I booked, I asked if my unit was under warranty which then I was transferred to and other lady. She took care of me right away and said yes, the parts we're still under warranty. She also said that the owner, Dan, was making his rounds through Nixa to help since they were so booked and he will be at my house that day! Sure enough, he was there and got it fixed right away. He double checked everything to make sure it was working and said to call him directly should I still have any problems. So far, everything is working great and I really appreciate Dan and the warranty lady working so quickly to take care of us! read more

Had them install a complete system 6 years ago. Started having bad smell coming from the vents. Ends up that they had plumbed the condensation drain into a sewer pipe in my home and now our whole system and ductwork is full of sewage and all need cleaned/replaced. Dan knight told me it was past the statutes of limitations and would not agree to fixing the whole problem correctly. We had to file with insurance and have a different company fix it. read more

I finally replaced my 30 yr old system which had been originally installed by Knight. Anytime the old unit needed service they were always out the same day. I scheduled an inspection and the bid was ready the same day. Bid was reasonable compared with other bids. There was no pressure to buy and after I'd already decided on Knight, Dan told me to look in the phone book for his $200 coupon. That was free money! Installers were out the next business day to install and were professional. I will recommend Knight to family and friends read more

Excellent Work! They came out to replace our old air conditioner and did a wonderful job. The staff was very professional and they politely explained the new system to us. We will keep using this company and definitely be recommending them to all our friends and family! read more
