About US: McMahon Plumbing & Heating

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. Expecting your home’s air conditioning system to run all throughout the summer without any kind of maintenance is like expected someone to run a marathon without any kind of training or stretching: likely to end in disaster. This is why it is so important to take the time now before the summer gets into full swing to have your system checked out by a professional. Getting your system tuned up now before it has to go into heavy use over the course of the coming months can be highly beneficial for a number of reasons.

  • Oil to Gas Conversions – Investment in your family’s future.

    Oil to Gas Conversions By Michael DeMattia, General Manager, McMahon Plumbing & Heating, LLC. A prudent investment in your family’s future. Changing older oil heating systems and swapping out to hi-efficiency, gas, heating systems has been all the rage for Boston area homeowners looking for a home improvement project with the greatest bang for the buck over the last few years. Homeowners heating with Natural Gas versus Heating with Oil currently still save between 25 to 50%, depending on Heating System efficiency. The cost of Number 2 Home Heating Oil today averages just over $2.00 per gallon which is dramatically lower than where it was just a year or two ago, mitigating what was once dramatic savings. However, oil market expert’s consensus opinion is that crude oil and consequently home heating oil prices will be substantially higher in the next year. Suffice to say, the current respite from excessive oil prices are likely to end by 2017. Indeed, the crude oil price is up from its low of $27.00 per barrel earlier this year to nearly $50 per barrel as I write this article. Additionally, rebates are offered by Mass Save, tax credits by the Federal Government, and low interest heating equipment loans are available to Mass Save participants. The effect of these programs is to ease the financial burden […]
