Lavimoniere Plumbing Heating & Air LLC works on heating, cooling and plumbing. Its website pitches new air conditioner installs and getting heaters ready for winter, and the company says it has been in business 32 years. It holds 4.4 stars from 164 Google ratings, and its BBB grade is A+. A recent customer said another plumbing company wanted to cut into their shower; Lavimoniere took the shower handle off, noticed the cartridge was loose and tightened it, and the shower works with no leak. A 2023 customer said Steve fixed a 27-year-old hydro heating system: he followed the customer down into a crawlspace, found a dead motor operating the fan, bought a new one at his supply store and installed it. A 2022 customer said he called back within a couple of hours about a gas-fed steam boiler that died, had it fixed in an hour and explained what was wrong. A 2025 customer said Steve fixed an old connection water leak on a boiler, and a 2024 customer said he replaced a kitchen faucet and fixed two slow-leaking bathroom faucets. A 2023 customer said a noon appointment came and went, and two voicemails left at 1 PM and 3 PM got no response. A 2022 customer said the owner agreed to take a job for Friday, then nobody came and calls went unanswered. A 2023 customer said he showed up 4 hours late with no call for a boiler appointment. A 2022 customer said that when asked when he could come for an AC problem, he said “I’m all set” and slammed the phone down. A 2023 customer wrote that he worked for time and materials, generally avoided quotes, and returned phone calls after working hours or between smaller jobs. Massachusetts lists a plumber licence, 12713-PL-M, and Rhode Island a plumber licence, JP002599, both as active and held by Steven Lavimoniere.
YouTube legend. Gained much knowledge over the years.
The other plumbing company I paid to come out who hasn't refunded any money, Quahog Plumbing, didn't even try to evaluate the situation and check the cartridge stating, "There isn't back access." They wanted to cut into my shower and charge me a crazy amount of money. I told them to leave. Lavimoniere came in, was able to take the shower handle off, which was something I couldn't figure out. He noticed the cartridge was loose and tightened it. The shower works perfectly fine with no leak. Hire people that do the right work not the work that will make them the most money. I'll be calling Lavimoniere Plumbing first from now on!
Learnt a lot from Steve. Much love from Australia
I was searching YouTube on how to purge the air from the boiler basement heating and found Steve’s videos, and he got me thinking because my boiler does not have shut off valves before, and after the circulator, and there is no drain valve on the circulator at all because it comes in through the top of the boiler, however, at the bottom of the boiler because that’s where the water comes in there is a drain valve, but watching his videos, he taught me something. I did not know turn off the boiler when purging the system, I was finally able to purge very little air from the system with Steve’s help because he gave me the knowledge and the courage and confidence to do this on my own, I do tackle many plumbing jobs throughout the house however I have called plumbers in the past because it is beyond my capability and that’s where honest hard-working individuals like Steve come in and let’s not forget Ms. Molly which are extremely honest, and the world would be a better place if we had more people like Steve, granted there are many many honest people out there, but sometimes that’s not the case. I love your YouTube channel and can’t get enough of it, I just wish that you would turn on the thank you button so millions of viewers can donate more to your channel and Ms. Molly that way you could feed her like the little princess that she is.
Steve is the best very knowledgeable about what he does. He worked on my boiler a few times and everytime I called him he was right there when I needed him I won’t use anyone else his prices are very fair and I will recommend him to anyone I know
