Heat pumps are the job people keep describing at Advanced Mechanical Systems, a Stow plumbing and HVAC contractor that says it has served New England since 1996. In a May 2026 Google review, a homeowner planning a total replacement and heat-pump conversion said Joe walked through the system, timeline and pricing without trying to upsell. In a May 2025 review, a Concord customer said AMS swapped an oil-fired furnace and water heater for a heat pump and heat-pump water heater in one day, removed the oil tank, adjusted the outdoor unit on the fly so it could not be seen from inside, and came in competitive with four other quotes. Service calls get similar notes. A June 2026 reviewer said AMS sent techs the same day, twice, for pinhole leaks in expansion tanks, and handled the latest replacement under a factory warranty. In March 2026, a customer with a Viessmann radiant system said Danielle found a leaking valve, talked through the repair and cleaned the boiler. Two reviewers, in March 2026 and July 2025, said the office helped with the Mass Save paperwork. The company holds 4.7 stars from 134 Google ratings and an A+ BBB grade. The complaints are dated. In a March 2024 review, a customer described an ongoing dispute: plumbers drilled large holes through joists, a radiator fell off the wall, and a freestanding tub drain leaked through a new kitchen ceiling; they said they fired AMS and paid another company to finish. A September 2021 reviewer said two ductless systems costing over $12K lost their refrigerant within three years and a follow-up repair cost over $1,800. A February 2022 reviewer gave four stars because an air purifier was installed backwards and took a while to correct. The Massachusetts sheet metal licence #13658-SM-M1, held by Joseph P Bolinsky, is active on the state registry.
“Advanced Mechanical Systems AMS”
“Then we got a quote from a smaller place, with Joe (an owner and installer) at Advanced Mechanical Systems (AMS) and it was about 20% cheaper”
I recently had Joe Bolinsky from Advanced Mechanical Systems install and finish a mini-split system at my home, and I couldn’t be happier with the result. Joe was professional, knowledgeable, and easy to work with throughout the entire process. The work was completed quickly and efficiently, with great attention to detail. He made sure everything was done right, and the finished installation looks excellent. It’s clear Joe takes pride in his work and stands behind the quality of what he does. I highly recommend Joe and Advanced Mechanical Systems to anyone looking for reliable HVAC service in Massachusetts.
I've used Advanced Mechanical Systems to service my furnace for the last several years and will continue using them without any hesitation. Twice in the last couple of years, I've had pin hole leaks in different expansion tanks on my boiler and hot water heater and on both occasions AMS has sent techs out the same day to fix and replace the tanks. Most recently, AMS handled replacing the tank under a factory warranty without any questions. AMS' technicians are personable, knowledgeable, professional and have answered virtually every question I've had about by complex HVAC system. I would highly recommend using AMS for any HVAC or plumbing project.
I used Advanced Mechanical for a total system replacement a few weeks back. I was thoroughly impressed with Joe in our meeting. He went over several things that I didn’t even think about considering. This company did not try to upsell me; Joe was courteous, professional and kept the meeting to a level that I could understand. Joe took the time to explain the system, timeline to install and pricing so I had no confusion. I would highly recommend this company to anyone considering a total replacement and conversion to a heat pump. I truly felt like they listened to me, recommended the best solution and did the work for a reasonable price.
I had a great experience with Advanced Mechanical Systems Inc. Bobby came to my home in Hudson (Dover Circle) for maintenance, and he did an excellent job. He was thorough, hardworking, and took the time to make sure everything was done right. I had previously hired Petro Home Services, and unfortunately, they only spent a few minutes checking things and didn’t do a good job at all. The difference with Advanced Mechanical Systems was clear right away. Bobby’s attention to detail and work ethic really stood out. I truly appreciate the effort he put in, and I highly recommend Advanced Mechanical Systems Inc. to my friends and anyone looking for reliable, quality service. -Marwan
I have a radiant system with a Viessmann wall unit (Hot water and boiler). I hadn’t serviced it for a couple years because I had other companies come and had little confidence I was getting any value. I had a valve spring a leak and called AMS. Danielle arrived and spotted the leak and talked me through the repair and issue. She offered a cleaning for the boiler and i gladly accepted. She also walked me through the boiler functionality, a few improvements I could make both physically and to the programming. She was direct, clear and a pleasure to deal with.
