HVAC reviews in Nixa, Missouri

Patrick Turnbow of Knight HVAC was a godsend after a major AC failure led to a flooded bedroom. He was prompt, professional and courteous. It was another company’s mistake but he took good care of it. Bravo!

They have really good customer service from the receptionist to the technicians. All of my very polite, courteous, always work around my schedule. They did a full exchange for me and they did it on a timely matter and had the job done and less than a full day so I was not even without AC A+.

Purchased a new HVAC system a few years ago and used them for repairs and maintenance since. This spring I showed repair guy a severed little wire that registers outside temp. He was literally there 10 min tops he didn't turn a wrench and they charged $90.00 then wanted another couple hundred to put a little wire on. After I voiced my opinion that was an unfair charge ($90.00) the service manager and another Karen in the office were very unprofessional and was spoken to disrespectful...lots of heat and air options out there. Perhaps if they discuss their charges and manner they do business and not talk down to a paying customer??? might be a bit more professional. Lost my business. I'll pay double before I accept shoddy customer service, i would never have spoke to a customer with the attitude and tone Karen and Linda spoke to me. I paid the $90.00 for a diagnostic charge that I showed personally showed him what was wrong. I asked for it to at least be applied to putting the tiny wire on, I think two screws on the outside....nope couple hundred bucks and had to be prepaid if I couldn't take off work and be home between 1 and 4.Prime example of the culture these days maybe can't control the exorbitant charges but sure can control who I give my money to.

Had Knight replace an old HVAC system. Every part of the service was flawless. Their sales, install, and follow up after the sale was fantastic.

My first call for all HVAC issues is Knight.

Patrick was very knowledgeable and helpful when coming to check on our air conditioner that wasn’t keeping up with the warmer temps. Very respectful of our home and worked quickly to solve our issue! Highly recommend!

Nobody likes having issues with their air conditioning in the summer…Knight did a great job from the girls in the office finding a time for me to have service, from Patrick quickly diagnosing the issue and getting it repaired (I believe within 30 minutes). They were all so pleasant and helpful. I appreciate you all!!

Patrick was wonderful—he installed our thermostat very quickly and set it up for us! He was very professional, knowledgeable, and friendly. We recommend him with no reservations! Great service technician!

After keeping our old furnace going for two decades. Dan and co. replaced our old pkg unit with a new Trane pkg unit. Darrell and his other brother Darrell did a wonderful job installing the new unit. Prompt, very personable, willing to answer general questions and generally, put up with me . Fair and reasonable. Completely knowledgeable. The only HVAC company we will call.

I’ve used Knight Heating and Air multiple times, and they consistently deliver exceptional service. Every time, their work is top-notch, and they handle everything efficiently and professionally. Their pricing is very affordable, which is a relief when unexpected issues arise. Plus, the team is always friendly and accommodating, making the entire process stress-free. I highly recommend Knight Heating and Air to anyone in need of reliable heating and air services.

They came out to perform our service on both the air conditioning and heating units they installed a year ago. Everything is still running fantastic. The technicians are very knowledgeable and professional! Andrew was our technician this time and he did an incredible job! Keep up the great work.

I have used them several times and they always show up quickly, they are friendly and professional. I know I am going to be charged fairly. They never up-sell or try to replace more than necessary. The blower on my furnace was rattling and they were able to repair the old part and didn't push the sale of a new one, but told me it was easily ordered and replaced if this one started acting up again. They are always my first call when my heat or ac start to act up. Last summer my thermostat was acting up because of a little bit of battery corrosion, and all he did was clean it up and charge me the minimum when I'm sure anyone else could have said the thermostat needed replaced. They are always honest and up front about the repairs being made, what was wrong, what needs to be replaced. They always give me all of my options and let me make the best decision for my budget as well. 10/10 excellent customer service. I am always so impressed with them and I hope they continue to be an excellent company moving forward because so far they are doing everything right!

Had my AC unit go out over the weekend. Called for the emergency services. They had someone out same day which was great, but that is where it ended. the technician diagnosed the problem, gave me an estimate and promised to be out first thing on Monday before 11am to finish the job. Monday rolled around and took off work to be home for this. No show. I called and spoke to the office to which they said that the technician does not schedule and therefor I was not added to his list and he also couldn't give an estimate and based off of the notes, it was going to cost more than what the technician said. They may or not be able to "squeeze me in today" either. So they were going to work on the pricing and call me back. Called back and told me the price was going to be triple what I was told. Worst service and I had to pay the fee for the technician to run diagnostics.

I have never experienced customer service this bad. I have paid for 2 units through Knights, an 11k for downstairs and a 8k for upstairs in my home. The girl I spoke with yesterday was beyond rude. The day before I asked for a simple request, just for an invoice to be sent to my email due to selling my home, and the new owners needing verification the unit was bought and paid in full before closing. I asked her name, because I had called the day before and talked to a girl that never sent it. She rudely said, "why do you need my name?" I mean you are a customer service representative? Right!! Why would someone not give their name, very strange, gave me a made up name Isabella, what kind of business are they running? Makes me scared to ever call them and trust them with my money. I should have spent my 20k worth of air conditioning units, and 10 years of maintenance calls somewhere else. I advised the new owners of this and hopefully they won't make the same mistake I did, which is trusting a company that won't even tell me their name, or complete the simplest and most mundane of tasks... Don't use them, they do not value you, your business, or your money. Period.

Had an issue with my heat pump not running for heat during this last cold snap and called to get on the schedule. Ramona was very kind and got me on the list for a technician within a couple days which was much faster than I expected. Kevin, Logan, and Andrew have been the techs that have evaluated, troubleshot, and made repairs to my system and all have been very professional and friendly. They got me up and going, and actually fixed another issue that I did not know I had to make my heat run even more efficiently. Very Happy, and now lifetime, customer here! Thank you guys for the excellent skills and integrity.

Very happy with Knight! We've used them twice, and have a scheduled third appointment. Technicians have been very respectful, calm, and knowledgeable. The most recent took the time to explain how he was diagnosing the condenser, just for my curiosity and information. Above and beyond, and a very reasonable price too.

We are so grateful for High Efficiency! Brad stayed after hours for us to tend to an emergency HVAC situation. He was friendly, knowledgeable and took his time with us even though I’m sure he was ready to get home after his long day. He answered all our questions and educated us on many new things and was able to print us a cost estimate on future services that we will probably need if interested. Thank you Brad!!

Excellent service. Tanner was great. He arrived and found the issue. He explained what he needed to do to have air up and running again for us. We had to have new system put in both outside and inside. Tanner arranged to install on a Tuesday but installed a day early. He made sure all work was completed to our satisfaction. He went above and beyond expectations. Would recommend.

Helped me over the phone through my problem , had them scheduled for the next morning and ended up canceling because I figured out the issue , they were very helpful and professional. Definitely recommend.

This is a great company. Highly recommended!

My AC unit needed some work and Tucker came out and got straight to it. He was super knowledgeable, efficient and didn't mind explaining things to me, best service I've had in years!

Handled our A/C problem quickly and efficiently and did not cost an arm and a leg. Friendly and informative technician. Would recommend
