Cardinal Plumbing Heating & Air Conditioning serves West Boylston from 30 Goodale St, with plumbing, heating, cooling, boiler, and water-heater work. Porch lists nine years in business, while the company is identified across directory profiles as a local plumbing and HVAC contractor. Homeowners described strong responsiveness and solid installation work in reviews dated 2019 through 2021. They praised same-day or next-day help, water-heater replacements, furnace and boiler installation, mini-split cooling, clear explanations, and careful cleanup. One 2021 review described a combi-boiler installation that worked well through the following winter; other reviews described furnace replacement and several water-heater projects. There are important service follow-up questions. A 2020 review said three mini-splits were installed successfully but a gas line was left unfinished despite repeated contact attempts. A 2019 reviewer later reported difficulty getting follow-up service after an otherwise good tankless-water-heater installation, and another described the price as high. The written reviews are older, so confirm current availability, warranty coverage, completion responsibilities, and the full price before booking. Cardinal is a reasonable fit for boiler, HVAC, plumbing, and water-heater work when the scope and follow-up plan are clear. Confirm who will hold the current Massachusetts license: the registry evidence lists license 4361-PL-C as expired, while BuildZoom reports the same HVAC/mechanical license as inactive or expired in 2024.
Zach and his younger brothers installed a combi boiler in my old house last year. The job was well done and they used good parts. The unit worked very well this winter and I am pleased with the result. They also remove all the old equipment and even remove some unused gas pipes on my attic at no charge.
I had my whole heating and cooling system replaced by them and it came out wonderful. Zach was great, very professional and did a fantastic job! I would highly recommend them.
STAY AWAY!!!! I hired Zach and crew to install three AC mini split units and a gas line for a heater. AC install went fine, BUT he never returned to complete the gas line. Did not respond to my calls, texting excuse after excuse. Eventually offered to give me my money back, but never did! PLEASE DO NOT HIRE!
They called me within minutes and came immediately , helped solving the problem , great service.
Great knowledge and great service. Very complete in the work and was willing to explain alternatives.
