We previously had our A/C replaced by Middlesex Mechanical. Every step of the replacement was explained thoroughly and professionally. We recently called them back for a heating issue and was quick with a response and came next day for … More a service call. The issue was thoroughly explained and given every option available for remedy. Middlesex Mechanical is a quality company with vast knowledge of HVAC systems. Thank you to Middlesex Mechanical for getting our heat back on!

I had contacted Chris to come by and give some ideas of what we could do in our basement before we started our renovation. He was very accommodating and professional. As soon as he entered the area that we were renovating, he immediately … More saw the areas that could be improved and gave us some very helpful advice. They were willing to work within our budget and were very competitive in their pricing. The work was completed within 2 weeks of Chris coming to our home. We are so thankful that we had Middlesex Mechanical come to our home and change the ducting in our basement. It is so much more functional and we are so pleased with the results!
