When our upstairs 23 year old unit stopped working on a Sunday, a quick call to D. McKeon had Service Manager Bob Best out within the hour. He was able to show me how to get the unit to limp along for a few days while we looked at replacement units. The next morning the I had a list of options and pricing from Bob and had a firm order in by the end of the day. Carlos and his crew had our new unit installed by the end of the week and we weren't even in town. We came home ten days later to a cool clean comfortable house, and now I can control our system from my phone.We have been happy customers of Dennis and Laurie for over thirty years. Everyone is helpful, courteous, and efficient from Shannon in the office to the tech's Preston and Billy. From emergency service to annual maintenance, we trust D. McKeon and you can too. Mark R. Moore... a happy D. McKeon customer.

Preston is very professional and gives great advice. Let me know what I needed and what wasn’t really a concern. Showed me proof on a meter that the part was bad which is great business practice (I would have believed him anyway). Normally I’m not home when he gets here, glad I was today, I learned a few things from him. My a/c was installed by them before I bought the house, glad I stuck with them.

We have been clients of D. McKeon for many years. Ever since did our first furnace replacement with them and saved money long term by installing a unit with lower BTU and a 2 stage Blower. We have been in our home for 43 years,, upgraded both of our systems twice and redone our upstairs duct work. Moved upstairs thermostat and rebalanced distribution for our comfort. All this work has been with D. McKeon. Preston has been our primary technician and we look forward to his semiannual visit to keep everything working as it should. All of our systems have had a long service life. I can only remember 2 breakdowns and D. Mckeon moved heaven and earth to locate parts and get us back online quickly.

Preston was very professional in performing a checkup of our 2 HVAC systems and took time to explain findings and answer questions afterwards.

Excellent local company: professional, prompt, responsive, and courteous. Previous HVAC companies had failed to fix our six year old Carrier heatpump's ongoing refrigerant leak and only added refrigerant at each repair call. We changed to McKeon for maintenance service when we accidentally entered their office while visiting a nearby business: McKeon's office staff impressed us with their genuine courtesy and professional demeanor. When McKeon's tech Preston came out for our spring maintenance check, he took time to explain what the leak might be and then located it in a kinked copper pipe. The following week Billy repaired the pipe and restarted the system, which now works well. Preston and Billy's competence and careful attention to detail fixed an issue that previous repair companies had skipped over. We would (and already have) recommended McKeon to anyone needing home HVAC maintenance or repair.

I highly recommend McKeon. They were professional and did an awesome job. They are experienced in this profession for many years and know what they are doing. The job was done quickly and properly. Would definitely recommend them.

If I could give this business zero stars, I would. We scheduled to have a technician come out to troubleshoot our unit for an issue we encountered. The day of I called to confirm the appointment and was informed that our appointment was removed from the schedule. I never informed this business to cancel the appointment and this business never informed me they were canceling the appointment. I requested to have the matter escalated and was transferred to Bob and that’s when the conversation went downhill. Bob is very rude to customers, does not care to hear your concerns and definitely lacks customer service skills, which is essential to sustaining a business. This company never accepted fault for removing my appointment from the schedule. Save yourself some time and call Ragsdale Heating, Air & Plumbing. I had such a pleasant experience with them and a same day appointment was scheduled.

We have had issues with the AC at our office. Unfortunately it has not been a simple fix. There have been quite a few issues with this company. FIRST AND FOREMOST BEING THE RUDENESS AND UNPROFESSIONAL CONDUCT by the tech that showed up. BOB was beyond rude, rolled his eyes, raised his voice, got a major uncalled for attitude and was anything but helpful. He contradicted himself as to if he could give an estimate on how long the service would take. Then got upset because he had to wait at 3pm the other day since we were not here" . The reason actually being that service was scheduled for 10am that day and no one came and no one called to cancel or reschedule. So we had waited and waited.Bob should not be working in a position where he interacts with guests and we have requested he no longer be the rep who services our office. He was the rudest person I have ever met who is representing a company. Unfortunately our landlord has an account here or we would take our business elsewhere. Hoping we can convince our landlord to set an account up for his buildings with a different company, where they value their customers and are at least polite and respectful of their time.

Repeatedly sent out people who were not technicians. Didn't divulge that they were not authorized Lennox service providers. Incompetent but apologetic. Still did not refund money received when AC still doesn't work.

We recently had our AC/Heating system replaced by your company. Bob Best did the presentation and signed us up for the installation. He did an excellent presentation, explaining the heating and the cooling systems, and offered a diverse range of system types and options, with a variety of prices. He also went over the financing options for the different systems. He did an excellent job throughout the installation and answered all of our questions. The crew that did the work was also very good. They were at our home on time, were courteous, cleaned up and did a proper installation. We requested some duct modifications be made after the installation and Bob and the crew came back and did a great job.We highly recommend Bob and your company to anyone looking to replace their AC/Heating systems. Over the years, this is the fourth time we have had the system replaced and Bob has been the best in every way. He is very knowledgeable about the systems, has hands on experience, which is invaluable and treated us like family. He was not just another salesman selling the product. He has been there for us.

My furnace quit heating on a Friday night. not a true emergency as the downstairs unit was keeping the temp livable. I call and left a message and was called back in just a few minutes. the tech very patiently and politely walked me through a few things to try. And gave me an option for service now or wait til Monday (which is what i did). I received a call Monday at just past 8AM. again very friendly and polite and a tech came out by noon. I felt like i was given very good info by the tech and we determined that the 20 year old system was better replaced than repaired. On Wed They came out ON TIME again and installed. a good looking job and the 2 service men were, again, very polite and had the furnace swapped in 3 hours. At which point the Service manager and the original tech came out and examined the install and commissioned the furnace .. then helped walk through programming the new 'smart' t--stat.. they also installed a CO2 alarm and left a couple filters ... all in all I am very happy with the whole transaction .. Highly recommend

Had no heat on one of the coldest nights of the year .. called McKeon Friday morning and they came out before noon. The serviceman knew exactly what was wrong, put in a new capacitor and changed the filters. He explained everything to me and showed me what he did and why.. and explained just how the unit works. I was amazed he took such care to explain everything! Thank you Preston you deserve an award for your excellence. I will always call on this company if I should ever need to, I can trust that they will do an excellent job at a very fair price !

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.

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.
