Precision Plumbing & HVAC is a Massachusetts outfit built around Marcin — reviewers name him personally in nearly every one of the business's 23 reviews, all five stars, spanning 2019 through 2023. The range runs from full-house replumbing to gas conversions to central air installs, and what keeps coming back is responsiveness: in a 2020 review, a homeowner who cracked a toilet tank on a Saturday got an email back from Marcin the next day and had the toilet replaced by Monday, with him rearranging his schedule to make it happen. The bigger jobs get the most detail. In a 2022 review, a homeowner described a whole-side-of-the-house replumb that uncovered cracked cast-iron waste lines, was coordinated around an unrelated exterior sewer replacement, and covered 2.5 bathrooms, a laundry room and a kitchen. In a 2021 review, another described Marcin and his team plumbing two new bathrooms — one in an attic conversion, one in a finished basement — along with new gas lines for a stove, washer and dryer. On the HVAC side, a 2021 review covers a central air install, another 2021 review describes swapping an old gas water heater and furnace for a high-efficiency combi boiler, and a 2020 review describes converting a furnace from oil to gas. Several reviews come from repeat, professional relationships rather than one-off jobs: in a 2020 review, an interior designer said she'd used Marcin and his crew on multiple bathroom remodeling projects for her own clients, calling the team consistently reliable. There's no negative review on file. For plumbing or HVAC work — especially anything urgent or tied to a larger renovation — this is a crew with a deep, consistent record behind it, though the newest review on file dates to 2023.

Marcin was very professional and attentive. He was great at communicating and was very quick to respond. They removed an old hot water tank and installed the new tankless system. I would highly recommend his services. Looking forward to working with them again in the future!
Marcin and team did a great job redoing the plumbing in my entire house. We also discovered cracks in our waste line and he replaced all of the original cast iron lines in the basement and coordinated with the contractor who replaced our exterior water and sewer lines unexpectedly. He was quick to respond to questions and requests, very reliable, and did a great job plumbing 2.5 bathrooms, laundry, and kitchen.
Marcin and his team did a great job with a big and complicated plumbing project. They redid the plumbing in a whole side of our house because we had a lot of leaks and were remodeling 2 bathrooms. They installed a shower, a tub, two toilets, two sinks, and a lot of other plumbing to improve the whole system. Marcin knows what he is doing and was good to work with throughout. We would recommend Precision and Marcin for any plumbing project!
Marcin and Jamie stand out not just based on the quality of the work, which was fantastic, but also because of their professionalism. We have worked with a lot of subs over these last 5 months and Marcin really, really stood out. He ALWAYS showed up on days when he said he would. He set and communicated expectations very well. I can't state enough how much these aspects of customer service contributed to my stressing his professionalism. His skill and knowledge were, of course, stellar but all the subs have done very good work, when they showed up.
Precision Plumbing & HVAC have been outstanding in every possible way. Super professional, knowledgeable, reliable and overall great people. Marcin and his team have been exceptional - they did everything from plumbing 2 new bathrooms (one in the attic and one in a new finished basement) with bathtubs, showers, etc; new lines, gas stoves, washers, dryers, etc. We are really happy with the service and would highly recommend! No better team than their team.
