Karns Mechanical Services
Karns Mechanical started as a small business in Karns, but since has extended its service area to Knoxville and beyond! Our service area has expanded to a 60 mile radius of Knoxville and surrounding areas. Karns Mechanical will always treat our customers like family because of its family! Mike's son, son-in law, and wife all work for the company!

They are prideful in their work and want to bring the best product to the customer. Founder Mike Jenkins has been in the hvac industry for 30+years and in the year 2000, he decided it was time to branch out on his own. Living in the Karns community most of his adult life, he also knew that this was the perfect place to start a family business.
Services
Karns Mechanical Services is the trusted local Knoxville HVAC company that works with you on every service call from start to finish. With 30+ years repairing HVAC systems, and no matter what model, size or type of heating and cooling system you have, you can rest assured we can fix it for a competitive price.
Without the support of your home furnace during Knoxville's winter months, the sharp cold air will finds its way into all the crevices of your home and starts taking over your climate control. There's a reason why it's called 'inside' and 'outside' and it's precisely to provide differentiation in the atmosphere, which includes the temperature.
There is no Air Conditioner Repair too big or small for our qualified trained technicians to handle. A Karns Mechanical licensed HVAC technician will inspect and test your current ac unit while giving you honest and reliable solutions. We offer Air Conditioning Repair on all Major Makes and Models and stock a large variety of Air Conditioning parts to ensure you're not left in the heat on a hot summer weekend.
The KMS family started this business back in 2000, and we feel incredibly blessed to still be living in the neighborhood and serving our Karns community. Every HVAC technician on our staff believes every customer should be treated like one of our own. That means getting to you fast, and fixing whatever is wrong as quickly and thoroughly as possible.
Commercial heating and cooling repairs are inevitable. At Karns Mechanical Services, we offer a wide range of heating and cooling services to meet all your commercial HVAC installation, replacement, repair, and maintenance needs. Don't let common commercial HVAC issues leave you, your employees, and your customers in an uncomfortable business environment!

There's a reason Karns Mechanical has such a high rating... It's because they are the best! I struggled for multiple years with my upstairs unit. I had used a couple different HVAC companies and never felt like I was getting great service. I finally bit the bullet this Spring and replaced the AC. Karns Mechanical came highly recommended. Turns out they had the best price, and more importantly, they had the best service!
Mike and Lois own the business. They're son works for the business. They were extremely professional, but also down to earth. They answered all of my questions, and we've had a

Highly recommend Mike Jenkins @ Karns Mechanical. He is a great guy who shows up anytime you have an issue (nights, weekends and holidays). They are very professional and very reasonably priced. Would not trust anyone else.

I gave Karns Mechanical Services a 5-star review. We called KMS after another company didn't bother to show up the day before or call. We called KMS in the morning and they showed up within the hour. Karns Mechanical Service staff; Mike, Louis, and their son took care of our problem. They were quick but yet very thorough. Made sure everything was… back to where it was before they moved it. They were very professional and very friendly. I highly recommend them to anyone that reads this review. And have already given their name to my friends and neighbors. This company is truly a family-owned

I do not have words to express just how impressed I am with this company! Our AC went out on a Sunday night in July. I called and they were able to come out early the next day. They were so professional and insanely quick to respond. They were able to diagnose and repair the issue very quickly. Their pricing is very reasonable and I HIGHLY recommend this company over any other around!

As a local Google Guide, I would highly recommend this family-owned business! Lori and James showed up at my house at 10 PM to fix our HVAC unit and were so nice. Our unit needed a new capacitor and they quickly fixed the problem in about 20 minutes. Definitely will be calling them again if we need anything, support your local businesses!

Mike and his team are the absolute best! Used them for the first time today and could not be happier with their service! Our AC was running but not blowing out cold air, so we called this morning and they were here within 2.5 hours! They identified the issue instantly and replaced the broken part within 30 minutes. SO fast and extremely affordable! We will always use them from now on and will recommend them to all our friends and family! Thank you Karns Mechanical Services!!

I seriously could not recommend Karns Mechanical any more. They were fantastic! They came out on Sunday morning & fixed my A/C after my landlord called SEVERAL others who either didn’t return calls or refused to even come look at it despite advertising “24hr service”. Very professional, prompt & reasonable prices as well! 5 ⭐️ for sure!

I cannot recommend Karns Mechanical more highly....I called them on a Monday morning first thing, when I had realized the previous day that our A/C was not working appropriately. Lois called me back right away and they came that same morning to check out our units. We unfortunately needed to replace both of our a/c units, but they gave us a fair… price the first time (no having to negotiate or other pushy sales tactics) with great financing options. They showed up exactly when they said they would and fit us in to have both of our units replaced the same week. They were very professional
