DeLeo Mechanical Services

DeLeo Mechanical Services is a heating and cooling outfit run by Alfred and Michael Deleo out of Dunshire Drive in North Chelmsford, and on its Porch page it puts itself at more than eleven years in the trade. The permit record is where this business is easiest to see. Fifty-seven permitted Massachusetts projects sit under the name. Through the 2010s they read as sheet-metal and heating work: a gas furnace with central air on the first floor and a heat pump above it in Newtonville in 2015, ducting alterations off an existing system in Newton Center the same year, two forced hot-water air systems with all ducts in Arlington in 2014, and a three-zone gas heating system in Manchester in 2020. From 2020 onward the filings shift toward plumbing and gas — water piping for two dozen fixtures at a Needham Heights job in 2022 and 2023, an indirect water heater and cross connection in Hingham in 2024, replumbing and regassing a unit in Arlington in 2021. The written record from customers is thin and dated. In a February 2017 Angi review a homeowner who spent about $4,500 wrote that the crew got to work right away, worked quickly and neatly, charged a good price, and left the job better than he had expected — and, in the same breath, that the contractor was hard to get hold of. That single rating is what both Angi and Porch show as a 5.0. The licensing picture needs checking. BuildZoom lists three Newton and Massachusetts sheet-metal records for the business as inactive, expired or previously cancelled, including one it describes as an HVAC/mechanical contractor licence that expired on 28 February 2017 and which it re-verified as expired in 2022. Those are a directory's records rather than registry findings, but they all point the same way. If you are calling about a furnace, central air or a boiler, this is a long-running two-Deleo shop with a real, current permit trail. Ask for the current sheet-metal and plumbing licence numbers and check them against the state board, and settle upfront how you will reach them once the job starts.
