The Harmony Corridor story is the first-replacement wave. Builder-grade furnaces and air conditioners installed in the 2000s and 2010s are reaching 15 to 20 years in large two-storey homes with complex rooflines and attached three-car garages — and the live complaints are upstairs cooling, zoning and duct balancing, not total system failure [INFERENCE]. These homes already have gas, so the upgrade conversation is heat-pump and dual-fuel: a cold-climate heat pump that carries the shoulder seasons, with the gas furnace as backup on the coldest nights. Fort Collins code requires primary electric-only central heat to be a cold-climate or ground-source heat pump, and new forced-air systems in Fort Collins are sized from a Manual J load calculation at altitude — the City requires load calculations for new forced-air systems — at 5,003 feet, a gas furnace derates roughly 12% from its sea-level rating, so sea-level sizing undersizes a home here.
Area status: OFFICIAL corridor plan — Harmony Corridor Plan (adopted 1991, revised 2003). This is a corridor page, not a neighbourhood page. South of Harmony Road is “South Fort Collins” in common usage, but the corridor itself is a planning area, not a single residential neighbourhood. This page covers the corridor and the South Fort Collins subdivisions around it — it does not pretend Harmony Road is a neighbourhood with a boundary polygon.

Harmony was a farming settlement from the early 1870s, with a school (Muddy School, 1878), a church, a general store, a train depot and a grain elevator. Harmony School, at the north-east corner of Harmony and Timberline, was built in 1931 as the third incarnation of Muddy School. Harmony Cemetery, at the south-west corner of Harmony and McMurry, dates to 1891 with no burials since 1940, and the Ziegler farmhouse — Harmony House — is the only surviving farmstead building. The corridor's residential subdivisions have more HOAs than the older parts of the city; individual HOA names and fees need verifying per subdivision, so check your HOA covenants before moving exterior equipment.
