Atlantic Mechanical Contractors

Atlantic Mechanical Contractors is a family-owned commercial HVAC and refrigeration contractor based in Weymouth, working for businesses in Massachusetts and Rhode Island. It offers commercial service and repair, preventive maintenance, design-build HVAC and refrigeration systems, and energy conservation projects. Its refrigeration designs can cut a business’s refrigeration costs by as much as 40 percent and can qualify for large utility subsidies, which matters because refrigeration is often a business’s number one cost.

Paul Gratta started the company in 1980 as Atlantic Refrigeration, and he remains closely involved in daily operations. Early milestones included building its first supermarket, Milton Marketplace, and a large walk-in freezer for an ice cream distributor, built from the foundation up. After rebranding as Atlantic Mechanical, it became the first company in North America fully trained in Daikin VRV technology and has installed full systems using CO2 as the refrigerant.
