Furnace Installation & Replacement in Sheridan

A manufactured home needs a furnace built and listed for manufactured housing, typically a sealed-combustion downflow unit that draws outdoor air and vents through the roof. A standard residential furnace isn't a substitute. We match the replacement to the home's duct connection and roof jack, and set it up for altitude like any other gas furnace.

In Sheridan, the 55+ manufactured-home communities make up a meaningful share of the city's housing. Where a park has its own rules about contractors or work hours, we follow them, and we check with the city on any permit specific to manufactured housing.

Around 25% of Sheridan houses heat with electricity. If yours has an aging electric furnace, a heat pump is usually the strongest replacement: it delivers several times more heat per kilowatt-hour on most winter days and also cools. Colorado's $1,000 air-source credit and Power Ahead Colorado's $1,500 cold-climate rebate can lower the cost; the federal 25C credit ended after 2025. Our guide to heat pumps in Denver winters covers performance on cold nights.

At 5,286 feet, a gas furnace runs at about 79% of its sea-level rating once it's converted for altitude with the right orifices and pressure. We size from a Manual J. Small ranches with updated windows often need 40,000 to 60,000 Btu of input, not the 80,000 or more that was originally installed.

Since January 1, 2026, new gas furnaces in Colorado must meet 14 ng/J NOx or the current ENERGY STAR version. An ultra-low NOx 80% furnace can keep using the shared flue. A 97% condensing furnace vents in PVC, and the water heater left alone in the old flue may need a liner or a smaller connector.

The City of Sheridan Building Department issues mechanical permits under the 2021 IMC, and contractors must be licensed or registered with the city. We take care of the permit and inspection. A utility directory lists Xcel Energy for both gas and electricity in Sheridan; check your bill to confirm before applying for utility rebates.
