Grove asks a lot of a furnace
Winter nights in Grove average 28°F from December through February, and homes here need heat October through April, seven months of the year. A new furnace has to hold up to that stretch, not just the coldest week in it.
More than half of homes here heat with electricity, and the area has seen 12 winter storms and 47 damaging wind events over the past ten years. When the power goes out, a furnace that runs on electric ignition and blower motors goes out with it. Any furnace installed new has to meet the federal minimum of 80 percent AFUE, so the efficiency floor is already set. What matters after that is a unit sized and installed to run well through a long, cold season in a place where the power does not always stay on.

Oklahoma requires HVAC contractors to hold a state license.
The license comes from the Construction Industries Board, and it covers the contractor, not the job in front of them. That means the state has tested and keeps a record of the contractor doing the work. It does not mean an inspector signs off on this particular furnace once it is in.
That sign-off comes from somewhere else. In most cities and counties, putting in a new furnace needs a permit from the local building office, and the work gets checked once it is done. That covers the installation itself, separate from the license that qualified the contractor to do it.

- What size furnace does my house need?
- The right size comes from a load calculation, not the square footage of your house alone. A contractor measures your insulation, your windows, your ceiling height, and how the house is laid out, then runs those numbers to find the heat loss on a cold night. Winter nights here average 28°F, so that calculation matters. A furnace that's too big will short cycle and wear out faster. One that's too small will run constantly and still leave rooms cold.
- How do I know it's time to replace my furnace?
- Rising repair frequency is one sign, especially if the same part keeps failing. Uneven heat between rooms, a yellow flame instead of blue, or a furnace that runs longer to reach the same temperature are all worth having a contractor look at. Since homes here need heat from October through April, a furnace on its way out won't get much of a break before it's tested again. A contractor can tell you whether what you're seeing points to a repair or a replacement.
- Is a high-efficiency furnace worth it?
- It depends on how many months your furnace runs and what you're replacing. Homes here need heat seven months a year, October through April, so a furnace works harder here than in a place with a shorter heating season. Furnaces made since November 2015 already have to reach 80 percent AFUE at minimum, and high-efficiency models go higher than that, which means less fuel wasted out the vent. A contractor can walk you through what that difference means for your house, since venting and installation change with the higher-efficiency models.
