Heating & Cooling in Lexington, MA

Every housing era, expertly served. Book your free Lexington consultation.

The Battle Green may be frozen in 1775, but Lexington's neighborhoods tell the whole American housing story since: antique homes near the center, the famous mid-century modern enclaves of Peacock Farm and Five Fields, postwar colonials, and today's substantial new builds. Each era heats and cools its own way, and Lexington owners expect contractors who know the difference: radiant-slab moderns need different thinking than center-chimney antiques, and both deserve better than a one-size quote.

Lexington has also become one of the state's most heat-pump-forward towns, and we're glad to feed that momentum: whole-home conversions, hybrid setups, and mini-split additions, with qualifying installations potentially eligible for Mass Save® rebates up to $16,000. We verify eligibility, engineer the design, and install to the standard this town has expected since, well, 1775.
