Furnaces, AC units and water heaters, with Josh at the door: that is what customers of Provost Plumbing, Heating & Cooling describe. The Brockton, Massachusetts company, at 78 Provost Street per BBB, holds 5★ from 14 ratings on Google and 5.0★ from 13 ratings on Angi and HomeAdvisor, and its BBB grade is A-. Its Angi profile says Spanish and Cape Verdean Creole are spoken. The company's Massachusetts plumbing business licence, 4745-PL-C, has expired, according to the state registry. The written reviews run from 2021 to 2024. In an August 2024 Google review, a customer who had collected inflated quotes elsewhere said Joshua gave an honest quote close to what their old plumber charged and had the unit cleaned the next day. A January 2024 customer said Josh replaced their furnace during some really cold days at a reasonable price. In a November 2023 review, a customer described a new furnace, an on-demand water heater and added airflow to the lower level that did not take away from the airflow upstairs. AC calls come up too. A November 2023 customer said he came the same Saturday their central air quit and repaired it, and later installed 2 new thermostats. In an August 2023 review, a landlord said Joshua fixed an AC unit that kept cycling every 30 seconds the same day, and that they have used him for water heaters, no-heat calls and toilets at their rental units. A June 2022 review describes a new gas heating system with central AC, all the main ducts replaced, and new ducts run into 2 new construction additions.
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.
