Furnace Installation & Replacement in Lyons

Natural gas is available in town, while some properties outside town use propane, along with wells and septic. A propane furnace has its own orifices and gas pressures, and the supplier usually wants to inspect the line when equipment changes. If you're on propane and paying winter delivery prices, it's worth comparing a heat pump paired with a propane furnace; our dual-fuel guide explains how the system decides which to run. We haven't confirmed the gas company for every in-town address, so check your bill.

Sandstone buildings in the downtown historic district have thick walls and small interior spaces. A furnace may share an old chimney with a water heater, and running a new PVC vent through stone requires planning. An ultra-low NOx 80% furnace on a lined chimney is sometimes the simpler path. Steamboat Valley homes from the 1990s are more conventional, typically with a basement furnace on a metal vent or PVC, and are now at the age for a second furnace.

At 5,341 feet, a gas furnace delivers about 79% of its sea-level input after its high-altitude conversion. We size from a Manual J; foothill homes catch more wind than plains homes, and that raises the design load. Since January 1, 2026, new gas furnaces in Colorado, natural gas or propane, must meet 14 ng/J NOx or the current ENERGY STAR version. Some ultra-low NOx models need a separate high-altitude kit, so we confirm it arrives with the furnace.

The Town of Lyons contracts with SAFEbuilt for all building department services, with applications through the Community Core portal. A town contractor license is required to pull a permit, and the 2024 ICC codes took effect July 1, 2026. We submit the application and schedule the inspection.

Electricity comes from the Town of Lyons municipal utility, which buys power from the Municipal Energy Agency of Nebraska. Because Xcel isn't the electric provider, Xcel's heat pump rebates don't apply in town. Colorado's $1,000 air-source credit and Power Ahead Colorado's $1,500 cold-climate rebate still do, and Boulder County's Switch Together program has offered heat pump group pricing. Check with the town utility about any program of its own.
