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 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.

Ginger Banks

I called for assistance with an issue my husband and I were having, and spoke to a man named Bob. He was the most rude and unhelpful person I’ve ever spoken with at this company. Every time I spoke, he wanted to speak over me. It was almost like he was trying to make me feel extremely small, I will never work with this company again so long as this man works there. He has a very awful attitude, and as a woman I did not appreciate the way he spoke to me! He did not care about my business at all!

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..
