Provost Plumbing, Heating & Cooling, Inc. is a Brockton, Massachusetts plumbing and HVAC company that customers hire for furnace and air conditioning installs, water heater replacement, gas boiler repair, and general heating and cooling service. The company states on directory profiles that it has 5 years of experience and speaks Spanish and Cape Verdean Creole. Reviewers from 2021 through 2024 consistently name a technician, Josh, describing him as professional, responsive, and reasonably priced across 27 reviews on Google, Angi, and HomeAdvisor, all five stars. Specific jobs described include a June 2022 gas heating system and central AC installation with new ductwork run into two home additions, a furnace and on-demand water heater install that added airflow to a previously uncomfortable lower level, and same-day repairs to failed air conditioning units. One August 2023 reviewer reported using the company repeatedly across rental properties for water heater replacements and no-heat calls. The state's licensing registry shows this business's Massachusetts plumbing license, held under this company's own name, as currently expired — worth confirming directly before booking plumbing work. The Better Business Bureau, which grades the company A- based on how long it has been operating, opened its file only in March 2025 and lists a single employee. Angi and HomeAdvisor show the identical set of 13 reviews, a common cross-platform overlap rather than two independent bodies of feedback. For furnace, AC, and water heater work in the Brockton area, Provost's review history points to careful, communicative service with a consistently named technician — just confirm the plumbing license is current and ask about crew size for larger jobs.
I would highly recommend Provost. Josh is a true professional and very much a gentleman. He was reasonably priced and overall did a great job.
My go-to plumber retired so I had to call a few places to get a quote for maintenance service on my unit. Some of these guys are really full of crap! One even went as far as telling me he is the “best plumber in town” and that my unit will definitely require extensive (he is basically setting himself up for more work than needed). It wasn’t my 1st service so I know the normal rate and routine. But again, some of these guys think we are idiots. Anyhow, I found Joshua, he gave me a honest quote that is quite similar to what my old plumber would have charged me. He came by the following day, 2 hours later, my unit was cleaned and I am happy with his work.
Stand-Up guy. He’s honest. Josh did right by me. He’s honest, hardworking and knowledgeable. Keep this guys info…you want someone skilled but honest…that’s provost.
Josh is wonderful, he came on time and work hard, and we was very reasonable in price.
Josh, is extremely knowledgeable, he knows his stuff. He took care of my heating system without the high cost. He is honest, keeps his appointment, if he's running late he will inform you. I highly recommend him.
