Eight months of heat, and winters that test the grid
In Bluefield, furnaces run from October through May. That is eight months of the year, with winter nights averaging 25°F. A new furnace has to be sized to hold a house steady on the coldest nights, not just the mild ones at either end of the season.
Most homes here heat with electricity, and the power does not always stay on through a winter storm. West Virginia saw 35% of households lose power for 24 hours or more in 2024, and the last ten years brought 23 winter storms and 47 damaging wind events to work into that count. That is worth weighing when you choose a furnace and how it starts back up. Any gas furnace installed today has to meet the federal minimum of 80.0 percent AFUE, so a good share of every heating dollar already goes toward heat instead of waste.

West Virginia requires HVAC contractors to hold a state license.
The license is held by the contractor, not issued job by job, so it covers the business doing the work rather than any single installation. West Virginia's Commissioner of Labor is the one testing and keeping that record.
For a furnace install in Mercer County, that license is what stands behind the work. On top of it, most cities and counties in the state also require a permit for a furnace replacement, along with an inspection once the job is finished, so the work gets a second, local check before it's considered done.

- What size furnace does my house need?
- It depends on your house, not just its square footage. A contractor works out the size with a load calculation that looks at your insulation, your windows, your ceiling height, and how the place is laid out. Winters here push a furnace hard, with lows averaging 25°F from December through February, so one sized wrong will show it fast. Too small and it runs constantly without keeping up. Too big and it short cycles, wearing out its parts sooner. Skip anyone who quotes a size over the phone without seeing the house.
- How do I know it's time to replace my furnace?
- Watch for uneven heat, rooms that stay cold, a furnace that runs longer than it used to, or repair calls that keep coming back. Homes here need heat from October through May, eight months of the year, so a furnace that struggles has little time off to recover. If yours is old enough that parts are getting hard to find, or a repair would cost close to a new unit, replacement usually makes more sense than another patch. A contractor can tell you which side of that line your furnace is on.
- Is a high-efficiency furnace worth it?
- It depends on how much you heat and how long you plan to stay in the house. Every new non-weatherized gas furnace sold since November 2015 has to reach at least 80 percent AFUE, so even a standard model today wastes less fuel than older units did. A high-efficiency furnace sends less heat out the flue and more into the house, which matters more here given eight months of heating season each year. A contractor can walk you through the difference for your specific furnace and house.
