We have been customers of this company for more than 20 years. We have nothing but good things to say about them Even in the middle of a terrible snow storm they answered my call and helped troubleshoot our problem. Then they even called back to make sure we were ok. They are on time and neat. Very nice people!

Called them for after hour furnace service. The tech arrived on time. By then, we realized the problem was not with the furnace. He was very courteous and gracious about not needing the service. I will definitely use them the next time I actually need some work done.

Our AC stopping working yesterday. We have a yearly service contract with Michael Damion and called them first thing in the morning. They came out at 11:30 am same day and fixed our system. Ted was very knowledgeable and polite. Our home is cooling quickly and we are thankful for the quick service and not having a hot house in July. Great company! We have been with them for about 10 years. I highly recommend this small local business.

My service member Mike was probably one of the most professional and knowledgeable guys I have ever worked with. He was thorough, and explained everything along the way. Personally as I am guy who likes to be involved and know what’s going on during the process he informed me of every step along the way. I don’t know why I didn’t use this local hvac company sooner, but I would and will recommend this company to anyone since they have a high standard of professionalism.

Was short and sweet. Very nicely learned that it is better to buy a new one than fix the old. Serviceman was very well informed and checked the various components which could be causing the problem. He also did me a HUGE favor by getting out his ladder and climbing up to my roof to change two burned out spotlights. We are a house full of old women (83,78,60) and I could not figure out how I was going to get this done. I offered to pay him but he said no. ( I did tip him 😜

Purchased new residential Heating and A/C system that replaced a 28 yr old Furnace and 17 yr old AC which they originally installed and maintained. Service was fast and professional. The entire process was smooth and everyone (including the office and sales) was very responsive and provided numerous options. The installers (James and Paul) were professional, clean, efficient and hardworking. They provided clear explanations of the new systems and addressed all of our questions. Thanks!

Had this company come out, the central air was not working at all. I am a first time customer but they came out writhin 5 hours. I was expecting at least a few days wait. Turns out that a wire had been spliced that was behind the outdoor unit. We were charged just the standard service fee. I admire this companies honesty. AC is working great now.

I am new to Michall Daimion as I found a coupon to get a 18 point inspection on my heater for $89 in the local paper and decided to try a new company. When I scheduled my appt, I specifically stated that I had an "electric" heater and not a heat pump and that my unit had been maintained since it's installation years ago. I was told that the mechanic should be able to service my heater.
The mechanic arrived on time and was very mannerly. He pointed out that my unit was being used as an indoor electric unit and not a heat pump. He removed the top section of the unit and placed

We used Michall Damion to replace our furnace this winter when it broke. The good news is that they replaced the furnace within two days. When we returned home that night we expected to have heat; the bad news is the house was still cold. We called the office, and Michall came out personally and made the necessary adjustments. They did tell us they needed a particular piece of equipment to attach the air conditioning. Supposedly they installed it the following week. Memorial Day rolls around we put on the air conditioning, and it does not work. (Air conditioner is only 2 years old). We call
