Forest Lake homeowners replacing a furnace in 2026 typically pay $2,900–$5,400 for a complete gas furnace installation. Forest Lake is a growing Washington County city northeast of the metro, known for its lakes, rural character, and mix of established lakeshore properties alongside newer suburban developments. Homes here range widely — from modest 1970s–80s ramblers around the lake to spacious newer builds on large lots in the surrounding area. Furnace Direct serves Washington County with same-day delivery and factory-direct Goodman pricing.

Propane Considerations in Forest Lake
Forest Lake's rural and semi-rural character means some properties rely on propane rather than natural gas. Furnace Direct supplies LP-configured Goodman furnaces. At propane's significantly higher cost per BTU versus natural gas, 96% AFUE is even more financially important for propane-heated Forest Lake homes.
