Bartlesville asks a furnace to run seven months a year
October through April, your furnace is the thing standing between you and a house at 27 degrees. That's the average winter night here, not the coldest one. A new furnace has to hold up to that stretch every year it's in your house.
Most homes in this area heat with gas, and any new non-weatherized gas furnace made since November 2015 has to reach at least 80 percent AFUE. That's a federal floor, not a selling point, so ask what the unit you're getting actually hits. Washington County has also seen its share of winter storms and damaging wind over the years, and a quarter of Oklahoma households went at least 24 hours without power in 2024. Worth knowing which parts of a new system, if any, need electricity to run before the cold gets here.

A high-efficiency gas furnace would save about $100 a year to run in Washington County compared with a gas furnace.

Oklahoma requires HVAC contractors to hold a state license.
Oklahoma's license is issued to the contractor, not to any single job, so the same license that qualifies them to do HVAC work generally is what covers this furnace install. It means the state has tested this contractor and keeps a record of them, and that record applies here just as it would to any other job they take on.
A furnace install still needs a permit from the local building office in most cities and counties, with an inspection once the work is done. That is separate from the state license and checks the installation itself once it is in the home. In Washington County, 62.8% of homes heat with gas, so a permitted, inspected install is how this kind of job gets checked on the ground here.

- What size furnace does my house need?
- There is no size you can pick off a chart. A contractor sizes your furnace with a load calculation that looks at your square footage, insulation, window count, and ceiling height, because a furnace that's too big will short cycle and one that's too small will run constantly and still leave rooms cold. With winter lows here averaging 27°F, that calculation matters more than it would somewhere mild. Ask the contractor to walk you through the numbers rather than quote a size based on your old unit.
- How do I know it's time to replace my furnace?
- An old furnace with worn parts starts costing more to keep running than it did when it was new. Watch for uneven heat between rooms, a burner flame that's yellow instead of blue, or a furnace that cycles on and off more than it used to. Homes here need heat from October through April, so a furnace that's struggling has seven months a year to prove it. If you're calling for the same repair again in one season, that's usually the point to stop repairing and start planning a replacement.
- Is a high-efficiency furnace worth it?
- Every new furnace sold today has to meet 80.0 percent AFUE at minimum, so the real question is whether to go higher than that. A high-efficiency furnace burns less gas for the same heat, and with 62.8% of homes in Washington County heating with gas, that adds up over seven months of heating here. The tradeoff is a more complex furnace with a second heat exchanger and a condensate drain, which means more that can need service down the line. A contractor can lay out the efficiency levels available and price each one for your house.
