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

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 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!

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 t

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.
