Nine months of heat, and winter nights near 21°F
In Elkins, a furnace runs from September through May. That is nine months of the year carrying the load, with winter nights averaging 21°F from December through February. A new furnace here needs to be sized and installed to hold up to that stretch, not just get through a cold week.
Power is part of the picture too. West Virginia saw 35% of households lose power for 24 hours or more in 2024, and Randolph County has logged 37 winter storms and 56 damaging wind events over the past ten years. Any new gas furnace installed today has to meet the federal minimum of 80.0 percent AFUE, and that's the baseline a contractor will size and install around for this house.

West Virginia requires HVAC contractors to hold a state license.
The license is held by the contractor, not issued job by job, so it is the business itself that West Virginia has tested and put on record with the Commissioner of Labor. That record is what stands behind whoever comes to install your furnace.
In most cities and counties, a furnace installation like this one also needs a permit from the local building office, with an inspection once the work is done. The license tells you the contractor was tested and is on the state's record. The permit and inspection are separate, and where they apply, they are what confirms the furnace was put in correctly at your address.

- What size furnace does my house need?
- There's no single number that fits every house. A contractor sizes your furnace with a load calculation, which looks at your square footage, insulation, window area, and how the place is laid out. Going bigger than what the calculation says isn't a safety margin, it's a problem. An oversized furnace heats the air fast, shuts off, then starts again a few minutes later, and that short cycling wears out parts sooner. With winter lows here averaging 21°F, you want the sizing done right the first time, not guessed at.
- How do I know it's time to replace my furnace?
- Age matters, but so does what the furnace is doing right now. Watch for uneven heat between rooms, a furnace that runs longer than it used to, or a rise in your gas bill without a reason. If a repair tech has been out more than once this season for the same problem, that's usually the sign to stop repairing and start planning a replacement. Homes here need heat from September through May, so a furnace that's struggling has nine months a year to prove it.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and how much you run the furnace. Every new non-weatherized gas furnace sold has to hit at least 80 percent AFUE, so that's the floor now, not a selling point. High-efficiency models go higher than that, meaning less of the gas you pay for goes out the flue as exhaust. With heat needed here nine months a year and winter nights averaging 21°F, a furnace runs enough that the difference between 80 percent and higher shows up. A contractor can walk you through the AFUE numbers for the units they'd install in your house.
