Nine months of heat, and nights that drop to 16 degrees
A furnace in Cheyenne works from September through May, nine months of the year. On winter nights the temperature averages 16°F. Whatever you install needs to hold up to a long season and real cold, not just take the edge off on a mild evening.
Most homes here heat with gas, and any new non-weatherized gas furnace has to reach at least 80.0 percent AFUE under the federal minimum. Laramie County also sees its share of winter storms and wind, and power in Wyoming goes out for a stretch often enough that it is worth asking how your furnace and its thermostat come back once the power does.

- What size furnace does my house need?
- The right size depends on your square footage, your ceiling height, how much insulation you have, and how many windows face the weather. A furnace that's too big will short cycle, heating fast then shutting off before it warms the house evenly. One that's too small will run nearly nonstop once it gets cold and still struggle to keep up. A contractor works this out with a load calculation that looks at your actual house, not just its size on paper.
- How do I know it's time to replace my furnace?
- Age is the first clue, along with how often it's needing repairs. Once repairs start happening more often, or a single repair would cost a large share of what a new furnace runs, replacing it usually makes more sense than fixing it again. Watch also for uneven heat between rooms or a gas bill that keeps climbing without a reason. Nine months a year here depend on that furnace working, so it's worth paying attention to these signs before it fails on a cold night.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and what your current furnace is doing. Every non-weatherized gas furnace sold new has to hit at least 80 percent AFUE, so the question is really whether to go higher than that. A furnace with a higher AFUE rating burns less gas to make the same heat, and with winter lows here averaging 16°F and heat needed from September through May, that difference shows up on the bill most months of the year. A contractor can tell you what efficiency levels make sense for your furnace and your house.
