Advanced Comfort from Mitsubishi Electric 

As a certified Mitsubishi Electric Diamond Elite Contractor, we bring you access to some of the most advanced heating and cooling technology available. This elite status means our technicians receive ongoing factory training, keeping us at the forefront of ductless mini-split systems, heat pumps, and energy-efficient climate control solutions. Mitsubishi Electric systems deliver quiet operation, precise temperature control, and exceptional efficiency, making them perfect for New England's demanding seasons.

Our Diamond Contractor designation also provides you with peace of mind through extended warranties and exclusive program benefits that you won't find with standard installers. Whether you're looking to upgrade an older system, add climate control to a difficult space, or reduce your energy costs, we'll guide you toward the right Mitsubishi Electric solution with honest recommendations and expert installation backed by comprehensive warranty coverage.

Complete Solutions for Both Homes and Businesses

While many HVAC companies focus solely on residential work, South Shore Mechanical proudly serves both homeowners and commercial clients throughout our service area. We understand that businesses face unique challenges, from maintaining comfortable environments for employees and customers to managing energy costs and minimizing downtime. Our commercial services include everything from boiler and furnace installation to ductwork repairs, AC system maintenance, and emergency solutions that get your operation back up and running fast.

For residential customers, we offer the same level of expertise and attentive care. From heat pump and thermostat installations to air quality improvements and ductless mini-split support, we can handle every aspect of your home comfort needs. We're also an official Mass Save heat pump installer, which means we can help you access valuable rebates and incentives. And because we serve a diverse community, we're proud to offer services in both English and Portuguese.

From Braintree to Brockton, Weymouth to Holbrook, and everywhere in between, South Shore Mechanical has become the name our neighbors trust for honest guidance, clean work, and dependable service. We back everything we do with strong warranties because we stand behind our work and believe in building lasting relationships with every customer we serve.

    "Fantastic Experiences"

    They have helped us do routine maintenance on our home systems and replace a boiler unit. They are very professional, knowledgeable, fair priced, and very pleasant to work with.

    "Pleasant, Attentive & Thorough"

    We are very happy South Shore Mechanical helped us with upgrading our heating, cooling and water heater. They have always been pleasant, attentive and thorough.

    Laura F.
    "Great Company"

    Great company. They installed central A/C in my house. Came out great. Finished in a timely manner and cleaned everything up when they were done. Very respectful. Would recommend to anyone.

    James C.
    "Highly Recommend"

    I've used South Shore Mechanical for a full HVAC replacement and hot water tank replacement. Both times their pricing was extremely competitive compared to others and they've been great at communication.

    Meaghan D.
    "Phenomenal Crew"

    South Shore Mechanical is the best possible choice for switching from oil to electric heating. Phenomenal crew, very efficient, always go above and beyond, incredibly caring, very considerate of your needs.

    Aidan O.
    "Respect & Honesty"

    My dad had them come for an A/C issue, after taking things apart, found that the service switch was simply reversed. Very nice - and even refused payment, as he said he really didn't do anything.

    Mark M.
    "One of the Best"

    South Shore Mechanical is truly one of the best in the business. Highly recommend to anyone looking or an HVAC contractor!

    Bryan M.
    "High-Quality Service"

    South Shore Mechanical installed a new heat pump/ac system a few years. Needless to say it was a great job. Based on that performance, we decided to join the family of customers and signed on to service contracts.
