So happy we chose McKeon!! Bob was awesome and was very knowledgeable about our old system. Jacob and Brian made the installation go so smoothly! highly recommend this awesome firm.
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.
Fantastic company! Our for ace dies New Year's Eve a d we already habe a replacemet. Clean, kind and cost effective. Will used for all our future needs!
It was refreshing to find a company that actually seemed to care about customers. DMcKeon and staff are very professional and got the job done on time, on schedule and at the price they had quoted. I had a home warranty company contract that was cancelled immediately after seeing what honest service felt like. I highly recommend their services.
Excellent service and people that really care. I have used D. McKeon for over 20 years now. My 16 year old air conditioner was on its last leg and they installed a new one for me as soon as possible. I will always recommend Dennis and his staff. Thanks to all for helping me out. You are the best.
Always excellent service and reliable! Thank you for coming out last week, after hours, to make sure our A/C got fixed right away and we wouldn't have to suffer in the heat!
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!

Responded very quickly. Found the problem in a short time and able to make repair on the spot. Tested system before leaving. Very pleased with office help and technician service.

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.
