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.

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.

Great Services and kind office staf
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.
