I'm very satisfied with Jeff Mackay Mechanical. They are very responsive and easy to make an appointment with.

The people were prompt and arrived at my home at the time they said they would. The crew was professional and courteous.

They installed a new furnace and a whole new heating system for me. Everything turned out great; it's working just fine. I was so happy with their service that I wouldn't hesitate to use them again.

Very Helpful! Great customer service!

I recently used the services from Jeff Mackay Mechanical for some help with the furnace in my home and was very satisfied with the services they provided.

I had called them out because I was considering switching out my coal furnace for a new oil furnace. Jeff was very friendly and helpful while he was here and gave me great advice about what my options were.

Overall, I thought the services from Jeff Mackay Mechanical went very well, I will definitely continue to use them when I need, and I would highly recommend their services.

I called Jeff on Tuesday because my central air conditioner had stopped working. He said he would fit me in on Thursday to look at it.

He came as he said he would and had to order a part, but he came back today and had it working in no time.

Jeff Mackey installed a boiler and indirect hot water heater in our home. They were on-site as scheduled, performed the installation in a professional and craftsman-like manner.

I would have no problem recommending their services to a friend.

Positive: Professionalism, Punctuality, Quality, Responsiveness, Value

From the person who took my initial call to the professionals who quickly and efficiently identified the issue with my furnace, I was impressed.

Communication is outstanding, professionalism exemplary, and skill unquestioned. I do not hesitate to recommend Jeff Mackay and look forward to hiring them to do a more substantial project in the spring.
