East Coast Air LLC

East Coast Air is a Marshfield-based HVAC company that says it's veteran-owned and has served South Shore homes since 2005, focusing on heat pumps, AC, furnaces and boilers — with a particular focus on coastal salt-air installations. It's an authorized Mass Save Heat Pump Installer and a Mitsubishi Diamond Contractor, and its stated service area runs from Marshfield and Quincy down through Plymouth and Duxbury. Permit records on BuildZoom show ten completed HVAC installs — heat pumps, furnaces, AC coils and mini-splits — across Hingham, Marshfield, Cohasset, Norwell, Falmouth and North Easton, typically valued around $34,500 each. On Facebook, someone recommending contractors in the area named two of the company's people, Joel and Anthony, calling them easy to reach by text. For a heat pump or AC install on the South Shore, especially anything Mass Save-eligible, the certifications and permit history here are the concrete things to point to — worth a direct conversation about the specific equipment and rebate paperwork before committing.
