Seven months of heating in Poteau
Furnaces in Poteau run from October through April. That is seven months of the year, with winter nights averaging 31°F. A new furnace has to hold up through all of that, night after night, not just a few cold snaps.
Le Flore County has seen 12 winter storms and 96 damaging wind events over the past ten years, and in 2024, a quarter of Oklahoma households lost power for at least 24 hours. A furnace installed here should be one that starts back up on its own once power returns. Any new gas furnace also has to meet the federal minimum of 80 percent AFUE, so it turns most of the fuel it burns into heat for the house.

Oklahoma requires HVAC contractors to hold a state license.
The Construction Industries Board tests and licenses the contractor, not the job itself. Once a contractor holds that license, it covers the work they do across the state, so the same license applies whether they are installing a furnace in Poteau or anywhere else in Oklahoma.
For this furnace installation, the license is what stands behind the person doing the work, but it is not the only check on it. Most cities and counties in Oklahoma require a permit before a furnace is replaced, and an inspection once it is in, so someone from the local building office looks at the gas connection and the venting before the job is considered done.

- 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 a contractor needs to run a load calculation to know for sure. A furnace that's too big cycles on and off too fast and never runs long enough to heat evenly. One that's too small runs constantly and still can't keep up on the coldest nights, and here that means nights averaging 31°F from December through February. Don't size a furnace off square footage alone or off the unit you're replacing. Have a contractor calculate it for your house.
- How do I know it's time to replace my furnace?
- Watch for uneven heat between rooms, a furnace that runs longer than it used to, or a rising number of repair calls. An older furnace acting up is a lot more likely to fail on the night you need it most. Homes here need heat from October through April, seven months of the year, so a furnace that's struggling has little time off to make up for it. If yours is old and starting to act up, get a contractor to look at it before winter, not during it.
- Is a high-efficiency furnace worth it?
- It depends on how you heat now and how long you plan to stay in the house. Every non-weatherized gas furnace built since November 2015 has to hit at least 80 percent AFUE, so even a standard furnace today wastes less fuel than an older one. A high-efficiency model pulls more heat out of the same fuel, which matters more the longer your heating season runs, and here that season is seven months long. With winter lows here averaging 31°F, a furnace that wastes less fuel has more nights to prove it. A contractor can walk you through what makes sense for your house and price it out.
