Furnace Installation & Replacement in Henderson

Houses on acreage around the original Henderson community vary widely: farmhouses with additions, mid-century ranches and manufactured homes. Some have furnaces in crawlspaces or garages, and some have been added onto more than once. We look at where the ductwork runs, whether additions actually get heat, and whether the existing flue is sound. If your property uses propane rather than piped natural gas, the furnace has to be set up for propane, and we coordinate with your supplier.

Rural homes also tend to be more exposed to wind, which raises the heating load. A Manual J that accounts for exposure is worth more here than in a sheltered subdivision.

The newer production homes in the area generally have a basement furnace, a single thermostat and ductwork laid out by the builder. As those approach 15 to 20 years, the most common question we hear is whether to replace the furnace and AC together. If both are aging, matching them gives you better efficiency and one warranty start date, and it opens the door to a heat pump.

We also check what the builder left behind: how the furnace is vented, whether the return is large enough for the blower, and whether the condensate drains properly. Fixing those during the swap is quick. Leaving them means the new furnace inherits the old one's problems, from noise at the registers to a wet floor under the cabinet.

At about 5,033 feet, a gas furnace runs at roughly 80% of its sea-level input after high-altitude conversion. That conversion means the correct orifices, manifold pressure and, on many models, a different pressure switch. We size from a Manual J, not the old furnace's label.

Since January 1, 2026, gas furnaces sold in Colorado must meet 14 ng/J NOx or the current ENERGY STAR version. Your options are an ultra-low NOx 80% furnace that reuses a metal vent, or a 97% condensing furnace vented with PVC that needs a condensate drain. The NOx rule guide has the details.

Depending on the parcel, power is supplied by either United Power or Xcel Energy, and newer homes nearby are on Xcel gas. Older rural properties may differ, so check your bill. If United Power is your electric utility, Xcel's heat pump rebates won't apply, but Colorado's $1,000 air-source credit and Power Ahead Colorado's $1,500 cold-climate rebate still do. The federal 25C credit ended after 2025.

For propane homes in particular, a dual-fuel system can cut fuel costs by letting a heat pump carry the milder days.
