  We worked with Granite State Mechanical Services during our kitchen remodel to install a make-up air system for a new stove and hood. After getting five different quotes and hearing several approaches, we chose their team — and we’re so glad we did.

The entire team is professional, communicative, fairly priced, and does excellent work. This project ended up being much larger than we originally expected, but they guided us through every step, kept us informed, and made the process incredibly smooth.

They’re a second-generation family business, and Zak, Adam & Qwen are truly great people to work with. Highly recommend them for any HVAC work.

  Jack is an incredible technician.  Very personable, professional, efficient and informative.  Furnace stopped working during a major snowstorm and 7 degree weather and he got us back up in no time.  I've been with GSMS for many years and highly recommend them.

  Working as a renovation contractor for over two decades I dealt with many subcontractors over the years. I am happy to share that GSMS went above and beyond on a recent heating system install for me. They were very understanding of my current living situation, accommodating on every level and very professional. I highly recommend them.

  From start to finish GSMS was a pleasure to work with. Zak was knowledgeable explaining my options for a new boiler. Gina took care of scheduling ect and Adam did the installation.
You can tell this is a family business by the good feel you get from everyone.
Their pricing was far better than 3 other companies I spoke with. I would highly recommend using GSMS!!

  This was our first experience with GSMS and our service tech Quentin was a cut above what we’ve been used to. Friendly, knowledgeable, efficient and totally focused on satisfying our needs. It’s a comfort to know we have this level of service available to us when needed.
