FurnaceAge, for the Furnace You Inherited

Why it surfaced

FurnaceAge targets a wonderfully specific homeowner problem: figuring out what the large metal box in the basement actually is. Its best promise is also its most trustworthy one—“If we don't know it, we say so”—with ambiguous or unsupported numbers left unresolved rather than dressed up as certainty.

A furnace model-and-serial lookup tool that translates an unfamiliar data plate into age, manufacturer, equipment, and efficiency details.
