Most professional company I've dealt with in a while. I needed my HVAC units inspected ASAP due to selling of my house. Shannon was very helpful in answering all my questions and getting a tech out immediately.Preston came to the house, serviced and made minor repairs the same day He also went above and beyond spoking to the buyers answering theirconcerns as well. Can't say enough about the wonderful experience I had dealing with D. McKeon Electrical!Thank you Shannon and Preston!

D. McKeon Heating and Air is an excellent choice if you’re needing a repair or looking to replace your HVAC system. Great service and follow-up, their HVAC techs are extremely knowledgeable and courteous. We had both our upstairs and downstairs systems replaced, and right now HVAC equipment is in short supply. D. McKeon Heating and Air went out of their way to locate the equipment needed for the replacement of our systems.

I have worked next door to D Mckeon for 13 years. My parents called me Sunday evening, air is not working. I called D Mckeon, Mrs Lori answered the phone, and took care of the appointment information. The technician showed up, and had the system repaired, and serviced within 1-1/2 hours, the very next day. Professional service, awesome pricing, and timely repair....5 plus stars!! Thx everyone!

Preston the tech that came out was great. He found a hard to find freon leak during a PM maintenance! They are always great (D McKeon) but Preston was exceptional!

My review is sort of mixed here. After extensive research to have an evaporator coil replaced including labor freon parts etc... D. McKeon was by far the most expensive of 5 different HVAC companies @ $2,500 to replace an evap coil. Thats minimum $700 more for the same work, and i have done my research(you would think returning customers would at least get some type of break). I have used DMckeon for maintanence and tune ups and they do decent work, but good grief thats pricey as heck, and other HVAC companies thought so as well. Anyway, do your research as i did and am able to purchase the coil for about $600 and will have it installed by an old Army buddy I served with in the middle east, an HVAC tech, for free. Should not cost that much. DO YOUR RESEARCH AND GET LOTS OF QUOTES!

When our old AC went out on a hot Saturday night in August, we thought it would take forever to get relief. To our surprise, McKeon came out Sunday morning, made interim repairs to get us through and installed a new system three days later! On the day of the install, their supplier ran into a problem and didn't have the unit we ordered - so McKeon actually upgraded us to a top of the line model for the same price! We have never had such stellar customer service! The people are knowledgeable, friendly, great to work with and the new AC is incredible - quiet, highly efficient, works like a charm. We recommend highly!

D. McKeon Heating & Air Conditioning has been my HVAC expert of choice for almost 20 years. I have a twice yearly maintenance contract with McKeon and am happy to say my HVAC is still working - thanks to the excellent service this company provides. The staff at McKeon always goes above and beyond the call of duty.

McKeon has been our preferred service provider for many years. Their personnel know their trade and do not leave the job without ensuring that every issue has been addressed. In almost all cases, they have taken actions that were not precisely part of the job, but made the system more reliable than it was prior to the service.

My initial introduction to this great company was with Bob who did my quote for me. Bob is not only extremely helpful and knowledgeable, but he is friendly and very easy to talk to. They were able to schedule me when I needed, which was right away. The installers were the bonus here. Jacob is a highly trained and skilled professional. I am positive this company sees the value in their best employees as they have been there a long time and speak very highly of it themselves. Thank you Bob, Jacob and team for doing such a great job. We will never use another company!!

It hit 27° and of course our heat went out leaving us in a 55° and dropping house. I called D. McKeon because they had 5 stars (which we now know why) and were really close to us in Kennesaw. They were able to get to us within an hour and the technician who came out was quick and informative. He talked us through everything he found gave us helpful suggestions and had the heat back on in a matter of maybe 30 min.After he left my husband said that they would be the people we use from now on. (You don't know my husband but he is VERY hard to impress!) So this was very high praise. We both felt more knowledgeable and informed about our unit and what direction to take in the future.Thank you so much D. Mckeon!

Very courteous and accommodating when scheduling appointments. Service is top notch, thorough and on time. Service provided by Preston is fantastic. No question is too basic as he takes the time to answer questions and point out options. We use them for annual furnace and air conditioning checks as well as ac repair about a year ago. Excellent and I’m sure you’ll be happy if you go with them.

After a horrible experience with Reliable Heating and Air (which left us without air conditioning for 5 days during 90° weather) we called D McKeon and had a new unit in less than 24 hours. The customer service provided by Crystal was helpful, calming and knowledgable. Kevin and Bob were amazing in getting the new unit installed right away. Pricing was also a noticeable amount lower than Reliable and we weren't pressured into replacing a working furnace. It's been about a month since our new unit was installed and I'm still so grateful for the care they provided. We are now lifetime customers of McKeon.

The professionalism of D McKeown heating and air is unquestionable. After making a decision to use this service company a year ago I have never been disappointed in their customer service. If you are shopping around for an HVAC company, I don’t think you could possibly not consider using D McKeon.

Excellent company that gives personalized care. They go above and beyond when you have an issue rather than run like some companies. We bought 2 units from them and had unfortunate issue with install of one causing leak and damage. Bob and staff went beyond to get everything back to normal as fast as possible. Mr. Mckeon even came to our home himself for initial consult and was incredibly nice and attentive. To top it off, when they learned we were Cubs fans, they went out of their way to get us great seats to the CUBS vs BRAVES game! Special thanks to Mr. Mckeon and Bob for these tickets!! It made a great family memory for us!. The entire staff makes you feel like family!
