Eight months of heat, and nights that drop to 25°F
Oak Hill needs a working furnace from October through May. On winter nights that average 25°F, a new furnace has to hold that line night after night without a break.
A gas furnace installed now has to reach 80 percent AFUE at minimum. That is the federal rule for non-weatherized models. Power matters too. Close to half the households here heat with electricity, and the county has seen 19 winter storms and 73 damaging wind events over the past ten years. Worth asking what your new furnace needs to run, and what happens to it if the power goes out.

West Virginia requires HVAC contractors to hold a state license.
The license comes from the West Virginia Commissioner of Labor, and it covers the contractor, not the individual job.
For a furnace installation, that license is what stands behind the person doing the work. In most cities and counties, the job also needs a permit from the local building office, with an inspection once the work is done.

- What size furnace does my house need?
- The right size depends on your house, not just its square footage. A contractor works this out with a load calculation that looks at your insulation, your windows, your ceiling height, and how the house holds heat through a night that drops to 25°F. 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 when it's coldest. Since homes here need heat from October through May, getting this number right matters more than it would somewhere milder.
- How do I know it's time to replace my furnace?
- Age is one sign, but how the furnace is running matters just as much. If you're calling a contractor out more than once a season, the money is often better spent on a new unit than on another repair. Also watch for uneven heat between rooms, a furnace that runs longer than it used to, or a yellow flame instead of blue, which points to a combustion problem that needs attention regardless of the furnace's age. A contractor can look at the unit and tell you whether it's worth repairing again or replacing.
- Is a high-efficiency furnace worth it?
- It depends on how much your furnace runs and how you weigh the higher upfront cost against lower fuel use. Here, homes need heat eight months of the year, October through May, so a furnace gets more use than it would in a warmer state, which gives efficiency more time to matter. Any non-weatherized gas furnace made on or after November 19, 2015 has to reach at least 80 percent AFUE by law, so even a standard unit today has a baseline of efficiency built in. A high-efficiency model goes higher than that minimum, and a contractor can walk you through the actual models and what each one costs installed.
