About Us

Who We Are

HVAC Experts Committed to Your Comfort

Founded by William Holley, a former automotive expert, South Shore Mechanical has always been about more than just HVAC services. William transitioned from cars to HVAC because he loved the variety that comes with visiting different homes and construction sites. He took that passion and built a team around it. Today, we boast 30 years of unmatched experience, ensuring we’re not just technicians but trusted advisors. Our amazing service, top-notch communication, and competitive pricing set us apart from the rest. We’re not just licensed and fully insured; we’re committed to going the extra mile, making sure your residential or commercial spaces are as comfortable as possible.
