Skiatook needs a furnace built for a long, cold season

Winter nights here average 27°F from December through February, and homes here need heat from October through April. That is seven months a year your furnace has to work, cycling on and off through cold nights again and again.

Any non-weatherized gas furnace made since November 2015 has to reach at least 80 percent AFUE, so that is the floor for a new install, not the ceiling. This area has seen 12 winter storms and 97 damaging wind events over the past ten years, and a quarter of Oklahoma households lost power for at least a day in 2024. A furnace that comes back on by itself when the power returns is worth having when the cold and the outages tend to arrive together.

Oklahoma requires HVAC contractors to hold a state license.

The Construction Industries Board tests and licenses the contractor, not the job itself, so the license tells you the person or company is on record with the state and passed the exam the state requires.

For a furnace installation in Osage County, that license is what backs the work being done, but the local building office is what checks it. Most cities and counties here require a permit for a furnace replacement and an inspection once it's in. That inspection is what catches a bad gas connection or venting mistake, since that's the part of the job that can hurt someone. Gas heat runs 42% of homes in Osage County.

What size furnace does my house need?
It depends on a load calculation, not the square footage alone. A contractor figures this by looking at your insulation, your windows, your ceiling height, and how much of the house is exposed to outside walls. A furnace that's too big will short cycle and wear out faster. A furnace that's too small will run constantly and still leave the house cold on those 27°F nights. Ask the contractor to walk you through the numbers instead of just quoting a tonnage.
How do I know it's time to replace my furnace?
Watch for uneven heat, rising bills for the same amount of use, or a furnace that cycles on and off more than it used to. If repairs keep stacking up on an older unit, replacement usually makes more sense than paying for another fix. Homes here need heat October through April, so a furnace that struggles early in that stretch is not going to get easier to live with as winter goes on. A contractor can look at the unit and tell you whether it is worth repairing again or replacing.
Is a high-efficiency furnace worth it?
It depends on how many months your furnace runs and what you're comparing it against. Homes here need heat for 7 months a year, which is a long season, and every non-weatherized gas furnace made since November 2015 is already required to hit at least 80 percent AFUE. High-efficiency models go higher than that, but the gain matters more the longer and harder your furnace works. A contractor can compare specific models against your actual heating load and tell you where the real difference is for your house.
