About US: McMahon Plumbing & Heating

plumber boston maBoston Plumbers & Heating Contractors

Harold McMahon was introduced to the Plumbing Trade by his Father-in-law, John Rooney in the late 1930’s. After serving in World War 2 Harold returned to Boston, and again to work in the plumbing trade with John. A decade later, with considerably more experience and competence, Harold struck out on his own and founded McMahon Plumbing & Heating in 1952.

At the time, Harold’s business centered around the new construction taking place in and around Hyde Park as Builders were providing housing for returning veterans from the War. Since the beginning Harold instilled a pride of craftsmanship and prioritized personal integrity in all his interactions. He demanded the same of all his employees including his son Michael whom entered the business in 1966.

Harold moved the business to its currently location in 1964. We have remained in the same location since. Although the focus of the company has changed to Residential Plumbing Service work, the firm remains a family endeavor, under the leadership of Michael F. McMahon. Seven decades later, the 4th Generation of McMahon’s, with Julie McMahon and Michael McMahon Jr.’s involvement, are still serving discerning home owners in the Greater Boston Area. Our company has continued to enjoy sustained growth and success, in large part, thanks to referrals, our outstanding technicians, and the pride and integrity that we take in our work and every interaction.

Today, McMahon Plumbing & Heating, LLC is an undisputed leader in the Residential Service fields of plumbing, heating, drain cleaning, and customer service.

  • 3 Great Benefits Of An AC Tune Up Before Summer

    With the spring months coming to a close and even warmer weather on the way, many of us are starting to finally put our air conditioning systems into heavier use, if we haven’t been already. While summertime brings a lot of fun outdoor activities and such along with it, this time of year is going to be particularly rough on your AC. When summer finally comes around, your air conditioning system is going to be expected to run almost constantly, and if it hasn’t been serviced at all since it went into hibernation at the end of last year, you could be setting yourself up for potential disaster.
