HVAC Repair in Eastside Fort Collins

The Eastside is the East Side Neighborhood Plan area — College Avenue in the west, Mountain Avenue in the north, Riverside and Lemay Avenues in the east, Prospect Road in the south. It was the City's first subarea plan, adopted in 1986, and it holds the oldest housing in the south and east set: circa-1900 houses on Remington Street, the Laurel School National Register District established in 1980, and the Button House at 711 Remington Street, built in 1888. It is also the only area in this set where historic-preservation constraints are a real HVAC consideration — and where 1970s commercial buildings on South Lemay sit beside 1880s houses.

HVAC in Eastside Fort Collins Done Right

The Eastside's HVAC story is historic-home retrofit. The 1880s–1920s houses on Remington Street and in the Laurel School district have no original ductwork, and the answer is ductless mini-splits or high-velocity small-duct systems, placed carefully so no exterior alteration harms the district's character. The Laurel School National Register District — established in 1980, with the Button House (711 Remington Street, built 1888) as a contributing element — is the only historic district in the south and east set, and it is the only place where preservation is a live constraint on equipment placement. Beside the houses, the 1970s commercial and medical buildings along South Lemay — the Garden Professional Building at 1501 South Lemay Avenue was built in 1972–73 and remodelled in 1995 — run on ageing rooftop and split systems, a separate commercial story on the same streets.

Area status: OFFICIAL plan area — East Side Neighborhood Plan (adopted 1986), later folded into the Old Town Neighborhoods Plan Keep the boundary exact: College Avenue west, Mountain Avenue north, Riverside and Lemay Avenues east, Prospect Road south. Do not extend “Eastside” south of Prospect or east of Lemay without noting the change.

The East Side and West Side plans were the City's first sub-area plans (1986 and 1989) and were combined into the Old Town Neighborhoods Plan. The Lemay realignment and overpass at Vine — The Landing at Lemay, 336 Class-A units plus eight single-family homes, proposed in 2021–2023 — is changing the eastern edge of the area. School assignments change — Poudre School District voted in October 2026 to close several schools before the 2027–28 year — so we never hard-code a school assignment from a neighbourhood name; check with the district by address. Landmarks are Laurel Elementary, the Poudre Valley Hospital area to the south, CSU to the west and the Poudre River and Riverside corridor to the east.

How We Execute HVAC Work in Eastside Fort Collins

A National Register district, 1880s houses and 1970s commercial buildings on the same streets. The work here is retrofit with restraint.

Laurel School district: retrofits that respect historic character

The Laurel School district's 1880s–1920s houses have no original ductwork, and the district's character is the reason the houses matter. An outdoor unit bolted to the front of a contributing house, or a lineset run across a facade, does real harm.

We place equipment where it is least visible and least intrusive — rear elevations, side yards, screened positions — and we use ductless systems that need only a small wall penetration. The design guidelines are voluntary, but the visibility precedent from Landmark Preservation Commission decisions is the standard we work to.

Lemay commercial buildings: ageing rooftop and split systems

The 1970s commercial and medical buildings along South Lemay — the Garden Professional Building at 1501 South Lemay was built in 1972–73 — run on ageing rooftop and split systems that are now 50 years old.

Rooftop packaged units and split systems in commercial buildings need a different approach from a single-family system: roof access, building management coordination and planned replacement between tenants. We work with building managers on diagnosis, repair and planned replacement.

No original ductwork: mini-splits and small-duct options

A circa-1900 house on Remington Street was built before central air existed, with thin stud spacing and shallow wall cavities. Standard ductwork does not fit, and cutting chases through historic fabric damages the house.

Ductless mini-splits and high-velocity small-duct systems are the two answers. We size by Manual J at altitude — 5,003 feet derates a gas furnace roughly 12% — and we check the building envelope before recommending a size.

College Avenue in the west, Mountain Avenue in the north, Riverside and Lemay Avenues in the east, Prospect Road in the south. That is the East Side Neighborhood Plan boundary from 1986, kept exact — this page does not extend “Eastside” south of Prospect or east of Lemay.

Yes — with careful placement. The district's character is the constraint, not a ban: no City document prohibits exterior HVAC here, and the design guidelines are voluntary. We place equipment where it is least visible and least intrusive, and we use systems that need only a small wall penetration.

Yes. The 1970s commercial and medical buildings along South Lemay run on ageing rooftop and split systems, and we work with building managers on diagnosis, repair and planned replacement — including roof access and coordination with tenants.

No. Colorado has no state HVAC licence. HVAC work in Fort Collins is licensed by the City of Fort Collins, not the state — Colorado licenses only electricians and plumbers at state level.

Contractor-quoted Fort Collins furnace installs ran $7,000–$10,000 in 2026 (Lion, Fort Collins) for ultra-low-NOx models, including permit, venting and commissioning. That is a published market range, not our price — your quote depends on the venting route, ductwork and system size.
