Weirton needs a furnace that can run eight months a year
Your furnace here works October through May, eight months of the year. December through February, winter nights average 23°F, and it has to keep up on the coldest ones as well as the mild ones. A new furnace has to be sized and installed for that kind of run time.
Most homes in this area heat with gas, and any new gas furnace built now has to reach at least 80 percent AFUE. That floor is set before you even pick a model. Power matters too. Across West Virginia, over a third of households went at least 24 hours without power in 2024, and this area has seen its share of winter storms and damaging wind. A furnace that depends on the power staying on is only as reliable as the grid feeding it.

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 your install, not a one-time sign-off for this furnace. West Virginia's Commissioner of Labor is the one who tested and recorded that contractor before they were allowed to take on jobs like this.
For a furnace install, the state license is what stands behind the person doing the work, but the installation itself still needs a permit from the local building office in most cities and counties, along with an inspection once it's done. That inspection is what catches a bad gas connection, which is the part of this job that matters most given that most homes here in Hancock County heat with gas.

- What size furnace does my house need?
- There is no single answer without looking at your house. A contractor sizes a furnace by calculating how much heat your home loses through its walls, windows, attic and floor, not just by square footage. Two homes the same size can need different furnaces if one has more windows or less insulation. Putting in a furnace that is too big or too small for the house causes problems either way, so this is worth having a contractor calculate rather than guess.
- How do I know it's time to replace my furnace?
- Watch for repairs that keep coming back, a furnace that struggles to keep the house warm, or one that is old enough that parts are wearing out across the board. Furnaces here run from October through May, eight months of the year, so a unit that is already worn puts in long hours before it gets a break. If a contractor is repairing the same furnace more than once a season, or if your winter nights average 23°F and the furnace cannot keep up, that is a sign to start planning a replacement instead of waiting for it to fail.
- Is a high-efficiency furnace worth it?
- It depends on how much you use your furnace and what you're replacing. Homes here need heat eight months a year, so a furnace runs a lot more than it would somewhere with a short winter. Every non-weatherized gas furnace made since November 2015 has to hit at least 80 percent AFUE, so the real choice is between that baseline and a higher-efficiency model above it. A contractor can walk through the difference for your specific furnace and house, since the right call depends on the unit you have now and what's replacing it.
