Nine months of heat, and nights that drop to 12°F
Newcastle needs a furnace from September through May. That is nine months of the year the burner is doing real work, not just a few cold snaps. Winter nights here average 12°F, so a new furnace has to be sized for real cold, not mild chill.
Any furnace installed new has to reach at least 80.0 percent AFUE, the federal minimum for non-weatherized gas furnaces. Storms are part of the picture too. Weston County has seen 60 winter storms and 102 damaging wind events over the past ten years, and across Wyoming 8% of households went at least 24 hours without power in 2024. A furnace that comes back on by itself once power returns is worth having when storms like that roll through.

- What size furnace does my house need?
- The right size depends on your square footage, your insulation, your windows, and your home's layout, so there's no number that works for every house. A contractor sizes a furnace by running a load calculation on your specific home, not by square footage alone. Two houses the same size can need different furnaces if one has more windows or less insulation. With winter lows here averaging 12°F, getting this right matters more than in milder places, since an undersized furnace will struggle to keep up and an oversized one will short cycle and wear out faster.
- How do I know it's time to replace my furnace?
- Watch for a furnace that can't keep the house warm anymore, one that cycles on and off more than it used to, or one that needs a repair call every season. Rising gas bills without a change in how you use the heat is another sign the furnace is losing efficiency. Age matters too. Homes here need heat nine months out of the year, from September through May, so a furnace gets heavy use and wears faster than it would somewhere with a shorter heating season. If yours is old and starting to show more than one of these signs, it's worth having a contractor look at it before it fails on a cold night.
- Is a high-efficiency furnace worth it?
- It depends on how much your furnace runs and what you're replacing. Every new non-weatherized gas furnace sold since November 2015 has to hit at least 80 percent AFUE, so even a standard furnace today wastes less fuel than an old one might have. A high-efficiency model goes higher than that baseline, and with heat needed here nine months a year, that difference adds up over a lot of run time. A contractor can look at your current furnace and your gas use and tell you whether the jump makes sense for your house.
