Advance Air & Heat Co., Inc.

Advance Air & Heat is a Marion, Massachusetts commercial HVAC, refrigeration and building-automation contractor that's been family-run since 1986, when Roger Lamy founded it; his daughter Karen Lamy DeSousa has run the company since 2003. It holds an active Massachusetts HVAC license and is certified as both a Women Business Enterprise and a Disadvantaged Business Enterprise through the state's Supplier Diversity Office. Reviews describe technicians as professional, clean and thorough. In a 2022 review, a commercial client credited the team with fixing a paint-booth heating problem that other companies wanted to solve only by replacing the unit entirely — Advance Air & Heat got the client operational again within two days. A 2025 review praised a window-related job for how clean and professional the crew was. In a 2020 mention, the company donated technician time to help ready two former nursing facilities in New Bedford for COVID-19 patient overflow. Advance Air & Heat serves commercial, industrial, public and non-profit clients across southeastern Massachusetts, Cape Cod and Rhode Island — Marion, New Bedford, Fall River, Taunton, Brockton, Dartmouth and Wareham among the towns it lists — making it a fit for commercial HVAC and refrigeration work in that region.
