Commercial HVAC Knoxville

We have used Charles Stone Mechanical for over 25 years. Always very satisfied. Great Service & People.

~ Dave Roland

I have dealt with Ken and Sherri for years. If you want something done right the first time, they are the ones to choose.

~ Steve Garrett

Our relationship with Stone Mechanical has always been prompt, professional, and courteous. I highly recommend them for all your mechanical needs.

~ Tom Short

Wonderful people! Our heat went out & we had another company say we needed a new unit for $5k. Cantrell’s came out & fixed it for $150!!

~ Crystal G

The new unit Randy recommended is saving us money on our utility bills! Much more effective and quiet, and was installed quickly.

~ April W

We have used Cantrell Heating and Air for many years. They are always prompt and timely. The service people are always courteous and respectful. We have always been satisfied and I would highly recommend them to my friends and family.

Our air conditioner stopped working on one of the hottest days of the season. We were told probably couldn't get anyone here until 4 pm. We went to buy a window unit to get us thru until they could get here. Jake called before we got home and said he was on his way. He was here repaired the unit and gone by noon. He was very professional and friendly and is our Hero.

Had the routine inspection service for my 2 AC units performed in late April. Came back from travel this week (5/23) and found the the downstairs unit hadn't been running for some time (temp well above setpoint on t-stat). Inspected the unit and found the blower cabinet door was sitting in place but not latched. Observed electrical tape had been used on the interlock switch so the unit ran following the inspection visit. All stopped when the tape let go. I put the cabinet door in place and latched it – system op resumed. The initial installation was very good as have subsequent maintenance checks over the years. This was not the expected quality service I paid for…

~ Philip G.

Erin helped us select the heating/cooling unit best suited to our needs and the team of Joe, Chip, Ronnie and Don installed the unit. The team did a great job removing the old unit and replacing it with a new system.. We thank them all for their diligence in getting the job done and quickly.

~ Carolann A.

I’m so grateful I chose AA-Air to replace both of my HVAC units. After getting the runaround from countless other companies, and dealing with people that didn’t show up on time, wouldn’t return calls, were not able to even acquire equipment to be installed or provide a timeline for when it could be done, I met with Larry who instilled confidence about his team and what is different about this company from others. I had a large group of installers show up on time, give me a courtesy call that they were on the way, were completely professional, explained everything I had questions about, and did a great job getting both units done in one day. I highly recommend this company.

City Heating & Air Conditioning backs up their words with action. Everyone recognizes that things don't always go as planned. That was the general theme of our Heating & Air system. Thankfully, we had contracted with City Heating & Air Conditioning.

Great team!!

I replaced my electric heat pump in July 2023. It's a American Standard 3.5 ton, SEER 15.2, Heat strip 15kw. Model 4WC75042. Since the install my electric bill kilowatt usage has dropped approximately 32% from the previous year month to month for the last eight months. The techs were very precise during the installation of the new unit. They were very professional.

~ Brent Ledgerwood

Terrific service, came after dark to help get our heat going & just in time too! 10 inches of snow 4 days later. We were comfy & cozy during the snow.

I called City, my hvac service provider, when my unit stopped blowing heated air. Because of the weather and awful conditions of some roads I was not sure if they would be able to get a technician to my home. But Chris arrived around 2 PM of the day of my call. He resolved the issue pretty quickly. My fan unit outside had frozen up. Chris was able to clear it and I have heat again. Great job and great service. Thanks City and thank you Chris!!

~ Wendy Brown

Sitting here in my home during these freezing cold temperatures, I am thankful for City Heat and Air and how they fixed my brand new HVAC unit. The company who installed the system refused to fix their mistake, and thankfully, Mr. Mike and Chris figured out the issue and repaired it. The heat in my home has never been so nice, and during a week like this, I am more thankful for it. Although this repair took place a little over a year ago (I should have gave my 5 star review then), City has been great to work with ever since.

~ Jennifer Ingram

City Heat and Air has installed multiple units for me over the years. Mike, Karen and the team at City Heat and Air are great. The show up when they say they will. Their prices are fair and the service guys are great! I will continue to call on City for my heat and air needs.

~ Jana Strader

The last thing you want to happen on the coldest night of the year is for your heater to go out. When it happened to us, we knew exactly who to call. Thanks to Jason and his team, they came first thing the next morning, identified the problem, proactively found our warranty info, fixed it, and were able to answer all our questions and keep us updated every step of the way. Very friendly, honest and professional!

~ Elisa T. - Knoxville

Jason is undoubtedly the best in the business here in Knoxville. Anytime I’ve needed him he’s been there to fix my HVAC problem in the same day. He’s amiable and honest and won’t charge you what these big companies will because he does the work himself. He owns a successful business based just on the referrals from satisfied customers.

~ Jake H. - Knoxville

EXCELLENT SERVICE! JC’s Heating and Air did a fantastic job repairing our HVAC system and they repaired some broken duct work underneath our house as well. Jason and his guys were friendly, knowledgeable and very helpful. They got our HVAC unit up and running like new again. They are now our go-to Knoxville HVAC guys.

~ Mike W. - Knoxville

Jason and his crew were outstanding in their work. They have done multiple jobs for us including replacing a complete HVAC system, replaceing ductwork and vents, and installing a mini split system. We would have no one else work on our house but Jason and JCs heating and air.

~ Lorraine P. - Knoxville

Warm and comfy. I called late at night and Nathan was here early in the morning. My new furnace was installed in a few hours. He is very nice, friendly and respectful. If anyone needs a furnace or air conditioner I highly recommend Pol’s Heating and cooling. They are located in Knoxville but they service other areas as well.

~ Christine Palmer

Excellent service Tech came out on labor day !!! Very professional and I highly recommend them, Kelly is great she answered the phone and answered all my questions !!! Great company will definitely use again !!! Thank you all so much for your help

~ Steev Cannata

Nathan and his crew provided absolutely amazing service. Nathan was able to work with me throughout the whole process of replacing my HVAC system, and he made it as painless as it could possibly have been. Couldn't recommend his service more highly.

~ Troy Polidori

Lucas worked really hard, but also efficiently, to fix what could have been a difficult to diagnose problem. He was respectful and very qualified. Chancey and Reynolds always does a great job, whether you bought your unit from them or inherited it from a previous owner!

~ R Kimrey

My AC went out at the beginning of July and originally I was told that it would be the end of the month before the part came, but Mr. Ehsan really came through for us. He managed to get the part in early and was able to get my unit fixed way before I thought it would be. So thank you again for your help Mr. Ehsan

~ Joseph Chiarella

Lucas was a great young man. He was polite, neat looking, explain what he did, things to do during the year, took his time, etc.

~ Lendelle Clark

Jerry came out to perform my semi-annual maintenance service. He was professional and very thorough. He called to let me know when he was en route, introduced himself upon arrival and promptly began working. Chancey & Reynolds also services the office complex where I have an office and I have always been impressed with any interaction I’ve had there also. Great job Jerry!!!

~ Bob LYON

It’s easy to say someone did a good job when the bill wasn’t as high as expected, but

~ Brandon Glover

John cleaned our dryer vent, and most urgently, replaced a duct extension that had fallen from the wall. He was amazing. He was right on time, explained everything he was doing, and in every way went above and beyond. Outstanding, I will recommend this company to anyone and I will be using them in the future.

~ undefined

I own a property management company, one of the number one causes of house fires are due to dyer vents. So we have now started calling duct doctor and will likely do it prior to each move in to ensure our tenants safety. The company was professionally from start to finish. Very easy to get a hold of, showed up on time, my tenant told me they did a great job and were very friendly. To anyone in the real estate industry looking for someone to refer for this scope of work, remember sometimes your only as good as the person you refer. Make sure it’s these guys.

~ undefined

Quick and efficient cleaning. We had duct doctor clean due to previous owner’s animals, and our cat allergies. The before -and-after pictures they send are amazing. Technicians were on time, careful around the house, and very friendly answering all of our questions. The service is a little bit pricey, but I think it was worth it.

~ undefined

These guys were fantastic!! They were on time, explained everything they were going to do! They wore masks and shoe covers, which was super important to me as I am “at risk” and they did a great job cleaning our ducts!! We can totally notice a difference! They gave us before and after photos as well! They are also very honest. They found a ring inside one of our air ducts and gave it to us right away. A little diamond and ruby gold ring! We would’ve never even known it was in there! They’re Aces!!
