Lemont is one of the oldest communities out here, settled in 1836, with a historic downtown built from the local limestone that once shipped out along the I&M Canal. A lot of homes near the Downtown Historic District and the bluffs above the canal are older properties running boilers, radiators, and furnaces that need someone who understands vintage systems, while the newer subdivisions toward Cog Hill and Waterfall Glen want their modern equipment kept in spec. We handle both, sizing and servicing each system for the actual home and giving you honest, no-upsell advice.
