J and L Energy

J and L Energy is a Winthrop-based energy-efficiency contractor built around the state's Mass Save program — the company's own site lists insulation, air sealing, heat pumps and mini-splits, thermostats, windows and roofing as its work, and it describes itself as a Mass Save partner. A 2024 feature on Westwood Living introduced owner Michael Greene and the company to readers ahead of the winter heating season, framing the pitch around lower energy bills and a more efficient home — a promotional piece rather than a customer account, but it puts a name to who runs the business. Worth confirming directly: what Mass Save incentives or rebates currently apply to your specific job, since program terms change.
