A 2023 customer wrote that the Gauthier team gave an estimate on a Monday and installed a Navien tankless system in 48 hours. That kind of plumbing and heating work is what Gauthier's Plumbing & Heating gets hired for. A Massachusetts plumber licence held by Gregory P Gauthier, number 11049-PL-M, is active on the state registry, and a Massachusetts HVAC licence held by Gregory P Gauthier, number 11346-SM-M1, is active on the state registry as well. Its BBB page shows an A+ grade and accreditation, and BBB lists the business as operating since 1976. On Google it averages 4.2 stars from 34 ratings. A 2023 customer with a sewer line backup said they arrived within a few hours, gave an estimate, came back two days later and fixed the problem at a price that customer called very reasonable. A 2023 customer said they were at the door 24 hours after the phone call, after two months of waiting on a competitor, and left the job site clean and tidy. In a 2024 review, a customer said they came out on a Saturday morning for a heating emergency. A 2024 customer said technicians Norman and Mark solved a problem with a leaking radiator in a recently purchased home built in 1941, showed them how to adjust the radiators, and charged a fair price. A 2025 customer called them easy to work with and thorough. A 2025 customer said the company installed a different, lower-priced furnace than the model they had contracted for, without their consent, and placed it at the opposite end of the house from where they had asked. That 2025 customer said they requested a refund of the price difference and that the owner gave a partial discount on the remaining balance. A 2023 customer said calls were not returned, the person who answered the phone was rude, and they went five days with no heat before calling another company. A 2026 customer said the company did not show up for a confirmed appointment and did not respond afterward.
Called and made a confirmed appointment. No call no show for the appointment and ghosted us after when we tried to figure out what happened. Went with a better company.
Excellent job! Easy to work with, great communications, very thorough and detail oriented.
I am writing to issue a consumer alert regarding a recent experience with a furnace installation company. I strongly advise against using this company due to dishonest practices, poor customer service, and inadequate communication. We contracted with this company to install a specific furnace model in our new home. However, without our consent or notification, they installed a completely different and lower-priced system. In addition to this deceptive practice, the installation was performed incorrectly. Despite clear instructions to the company's employees that the furnace should be placed with the other utilities at one end of the house, they installed it at the opposite end. When confronted, the owner claimed they were unaware of our plans to finish the basement. As a resolution, we requested a refund for the price difference between the furnace we ordered and the one they installed. The owner also provided a partial discount on the remaining balance to compensate for the additional expenses we now face. These expenses include either relocating the entire furnace to the correct location or constructing a wall to conceal the system, which will result in a portion of our basement being closed off. I hope this information helps other consumers avoid similar negative experiences. Sincerely, Lee
My daughter and I met with superb Gauthier technicians, Norman and Mark, in April. They might as well have been wearing superhero capes as they solved a serious problem regarding a leaking radiator in a recently purchased home built in 1941. We were fortunate that Gauthier had serviced this home with a previous owner and they were familiar with the system. What impressed us (in addition to expert experience and problem solving) was that we were educated how to adjust the radiators to assure that they work appropriately in the future and avoid additional problems. This is great customer service and builds a wonderful relationship and trust moving forward. We also felt that the cost was fair. Highly recommend Gauthier. Thank you, Greg, for having a great team and arranging a prompt appt. for us.
Excellent service and a fair price. Came out on a Saturday morning to take care of a heating emergency. Highly recommended. I won't use anyone else.
