Furnace & AC Services in Cottage Grove, MN
About 20 minutes from our Rosemount shop.
Cottage Grove spans generations of housing — 70s ramblers, 90s two-stories, and the new construction that keeps the city growing along the river. Groff Heating & Cooling has serviced all of it since 1991, with the same family-run approach at every address.
Whether it's a furnace repair in an established neighborhood or a first tune-up in a brand-new build, you get clear pricing, honest recommendations, and free estimates on replacement systems.
New-construction homeowners: your builder-installed system's warranty almost certainly requires documented annual maintenance. A yearly tune-up costs little and keeps that coverage enforceable — worth it long before anything breaks.
