All reviews for Marshall Mechanical, LLC.

I needed prompt service as I had no heat during a cold snap. I told Charlie I needed a new furnace installed asap and he made sure it was done the day.

I called on Monday and they were able to fit me in on Wednesday. They arrived on time, were pleasant, efficient, and clearly explained the problem with our A/C system. I will absolutely call them again.

Very easy to work with and the staff was extremely professional. They replaced a freon based AC/heating unit utilizing today’s improved technology. From start to finish it was a pleasure working with Marshall Mechanical.

Charley came out promptly when we asked, spec'd the project, gave us a quote quickly and the work was scheduled within 10 days. Guys onsite for the project did a great job, moved vents just as needed and actually made the return air duct vastly quieter. Excellent work all around. Many thanks.

Charlie was extremely responsive with our family when our system failed and needed to be replaced with incredible urgency in frigid weather. He was both professional and kind. Highly recommend!

As new homeowners, we have had a lot to learn and Charlie and Joey have been incredibly helpful. They’ve addressed our issues thoroughly and carefully and have answered questions clearly. We’ve also been impressed with how quickly they’ve come out (48 hours at most). Highly recommend!

Charlie and his team really came through for me and my family, Friday night sometime our furnace started tripping the rollout switch after many phone calls I was given the number for Marshall Mechanical , Charlie made a trip over Saturday evening to confirm our fear that it was time for a new furnace.
We were given options and a clear explanation of what we’d be getting and then first thing Monday morning they swapped our unit out .
Very friendly and professional and left zero mess .
I hope to only need their services for routine maintenance now.
Thanks guys Merry Christmas

Charlie Marshall and his team were responsible for the installation of many HVAC systems 5+ years ago for a builder that owned the rights to a cul-de-sac community in southern New Hampshire. I happen to be one of those homes. Charlie and his team installed a high efficiency HVAC system in an uninsulated attic which should never have passed inspection being that those systems require double ventilation or an insulated attic. I have been unable to find a reputable company to service this unit in all those years because of parts that were used that have been recalled or the fact that the system does not meet compliance. I have called Charlie Marshall on his personal cell phone many times over the years and have not received a phone call to discuss this matter.

Therefore, I find this review to be extremely appropriate to give buyers a buyer. Beware of what you are purchasing and installing in your home since this individual doesn’t seem to install things to code. This might be a one off, but Charlie had every opportunity to fix the issue and he did not.
