HVAC reviews in Kennesaw, Georgia

Chris was great. He came out quickly and was able to fix our upstairs AC just in time for my daughter’s birthday party. Super responsive and knowledgeable. Would definitely recommend his services.

Excellent work from Mr HVAC

Great guys, quick response, very competitive pricing. Hope I don’t need them for a long time but if I ever do they’re who I’ll be calling

Easy to work with, really good pricing and was able to install in 24-hrs. Thank you @Mrhvac.

Mr HVAC was fast to diagnose and fast to resolve the problem. The team was friendly, efficient, and professional.

Chris came out within a day from reaching out to him and had our AC back up and running within 30minutes, especially heading into summer! Highly recommend!

Chris was great! My AC went out on a Friday night and Chris was able to get to it Saturday and fix the problem. He was quick, professional and fairly priced.

Nest thermostat installed quickly and efficiently. I would rehire for any HVAC system issues in the future.

This Company is wonderful- my AC went out suddenly & they came the same day we called & then had it running up again by the next morning. VERY reliable, professional & courteous…..I’d highly recommend them!

They are very professional. They kept me updated on the arrival and installation time. The finished project was completed exactly as promised. Working with them was a breeze.

He did an amazing job fixing my ac unit. He was very professional, and knowledgeable. Definitely would hire again.

My air conditioner was humming and making noises and hot to touch outside. Something wasn’t right. I called Chris and he came out within 2 hours and and showed me what was wrong. A few parts replaced, filter changed and a cool house once again. Very honest and great pricing. Definitely recommend.

MR.HVAC solved my heating issue promptly and at a fair price. I highly recommend them and will use them again if needed.

Chris was fantastic! He was able to make arrangements to be on site that same morning as my call, and he arrived promptly at the time he promised.

Once here, he did a thorough assessment, diagnosed the problem, and resolved it - all in under an hour! On top of that, he explained everything, clearly, as he stepped through the process.

Fantastic job, and I will absolutely use this company again myself as well as highly recommend it to others.

Amazing! Customer service top tier. My air went out and it was rough. The communication, timing, pricing were all amazing. I would recommend him to everyone I know for HVAC services.

Received every quote under the metro-ATL sun before going with Chris at Mr HVAC to do a full system replacement. Straightforward, honest, and easy to work with.

The install techs were friendly, quick, and polite. Would highly recommend using for any heating and cooling needs.

I rarely write reviews, but Chris and Rob earned it today. From the moment I called, they were responsive, professional, and genuinely helpful. They showed up on time (a miracle in itself), quickly diagnosed the issue, and had my AC back up and running in no time — just in time for this heat wave.

What really stood out was how friendly and knowledgeable the technician was. No upselling, no nonsense — just honest, quality work. I felt like I was in great hands the entire time. If you’re sweating it out and need reliable AC help, call these folks. Seriously. Total lifesavers!

What great service! Chris came right out after I called and fixed my problem so quickly, I was amazed! Great professionalism. Can’t recommend this company any higher! So glad I called MR HVAC!

The Mr. HVAC team was knowledgeable and professional! Initially they presented us with different options and how each worked with our HVAC system, and they helped us understand possible causes for our AC unit failing. They worked fast and respected our home while they worked. Overall it was a great experience! We plan to continue working with Chris and team for servicing and (hopefully in the distant future) other HVAC repairs/replacements. Thanks Mr. HVAC team!

Called Saturday afternoon they came Sunday morning. No bullshit kind of service plus nice, courteous and a sense of humor. Hard to find that with the mega big corporate outfits. My new HVAC folks.

Look no further! After interviewing and having several top-rated HVAC companies assess my HVAC system over a few years and getting quotes, I am confident this is the best company in Metro Atlanta. Most of those other companies said I needed a new system several years ago when I did not!
