We have appreciated the friendly, knowledgeable and professional service D McKeon has given us over the years. They go above and beyond to make sure we are taken care of!
Preston of McKeon Heating and Air is the most knowledgeable young man of my system. He was polite and efficient. I want him back every six months.
12 years running they have provided outstanding service and consultation to keep our family’s home safe, warm and cool. Preston is a consummate professional demonstrating expertise, and attention to detail.I wouldn’t use any other heating and air company.
Responsive quickly when needed and consistently gives professional service. Preston and Lauri are knowledgeable and know how to solve problems in a timely manner.

They have been my heating and cooling company for several years. I had an upstairs unit replaced last year along with adding a wall heat pump unit for my newly renovated porch. It kept the space very cool in the summer and has worked flawlessly so far this winter making this room a true 4 seasons room. It is very quiet and efficient and increased the comfort of the attached family room with very little expense added to our monthly electric bill.

Preston came out assessed the problem and informed me of what was needed to repair including estimated cost. I had to wait for insurance claim approval. When I got the approval I called McKeon back and Preston came out the next day and installed new parts. My home is warm again thanks to McKeon. Great job guys.

Extremely professional. Preston was on time, got to work immediately, and when he was done looking at the system he explained to me how the unit failed, why it failed, and what he'd be doing to fix it. Highly recommend!

We had another company doing service on our HVAC system.. They claimed we had cracked exchanger (12 year old system they installed) offered to fix heat exchanger for 2400.00 but did not ever find resason for furnace not working. Offered us new system for 13k. Called McKeon and Bob came out showed us couple of options. Very professional and two days later we had new furnace with very little disruption and for a fair price.. They now have a new customer as we signed up for maintenance..

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.

The gentlemen that should up were professional, courteous, and efficient. That got right to work, cleaned up after themselves, and kept me informed throughout the time they were in my home. I'm very pleased. Keith
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.

We’ve used D’Mckeon for many years and they’ve provided consistently good service.
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.

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 !

Air went out today. Called at 11. Serviceman here at 2! Part replaced and done in no time! So glad we chose D. McKeon last year. They go above and beyond for their customers.

Last month our refrigerator water pump went out and water got into the air duct and it collapsed. Bob was out here within 30 minutes and told us what the problem was, how to dry out our garage and servicemen came out that afternoon to replace duct. We are forever grateful for him taking the time to help us out.

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!
