Cheyenne Weather and HVAC Load
NOAA's 1991-2020 climate normals put Cheyenne at 7,027 heating degree days and 341 cooling degree days per year. Heating is the bigger job here, and furnaces and heat pumps in Cheyenne put in far more hours than the air conditioner. On average, Cheyenne gets 169 freezing nights and 12 days above 90°F per year. Snowfall averages about 66 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 70,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

Cheyenne Housing Stock
Census figures put the median build year in Cheyenne at 1975, so a typical house here has about 51 years on it. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. Cheyenne has roughly 20,000 owner-occupied homes, or 67.7% of households.

Between 2020 and 2025, NOAA's Storm Events Database logged 47 hail days and 36 days with damaging thunderstorm winds in Laramie County. The largest hail reported was 4 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage. Laramie County also had 4 tornado days in that period. In Cheyenne, 18% of residents are 65 or older. For older adults, a house with no heat in January or no AC during a heat wave is a medical risk. Mention it when you call, since many companies put those calls first.
When Replacement Makes Sense
- The furnace is 15 to 20 years old or more
- Gas or electric bills keep climbing even though usage hasn't changed
- A repair quote runs past a third of the cost of a new unit
- A tech found a cracked heat exchanger, or the CO detector has gone off
What Moves the Price
- AFUE rating: a basic 80% unit vs. a 96% condensing furnace
- Permit and inspection fees, which the local building department sets
- New PVC venting if you move to a condensing model
- Condition of the existing ductwork and any changes it needs
- Single-stage, two-stage or modulating gas valve
- BTU size, which should come from a Manual J load calculation
For Cheyenne we raised the national figures about 22%, based on local income, home values and climate-based equipment sizing. Get at least three written quotes; real bids can land outside this range.
What the Quote Should Cover
- The permit and the manufacturer warranty registration
- The new furnace, filter rack and thermostat wiring
- Combustion and safety tests
- Gas line and vent connections
- Removing and hauling away the old furnace
Wyoming Permits, Efficiency Rules and Rebates
Wyoming falls in the DOE's North region. New split central air conditioners must meet at least 13.4 SEER2, and heat pumps sold anywhere in the U.S. need 14.3 SEER2 and 7.5 HSPF2. Equipment replacements in Cheyenne generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their Wyoming license or registration number and a certificate of insurance with the quote. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- Make sure all three quotes are for the same AFUE and staging, or you can't compare them.
- Look up utility rebates on 95%+ AFUE units before you buy.
- Ask for the Manual J load calculation in writing. Oversized furnaces are the most common mistake we see.
