Eight months of heat in Moundsville
From October through May your furnace is the thing keeping the house livable. Winter nights average 24°F here, so it isn't running on the coldest few weeks alone, it's carrying eight months of the year.
More than a third of West Virginia households lost power for at least 24 hours in 2024, and this county has logged 8 winter storms and 36 damaging wind events over the past ten years. A furnace installed here needs to hold up through that, not just run on a mild day. If you're putting in a new gas furnace, federal rules require it to reach at least 80 percent AFUE, so any unit installed now meets that floor.

A high-efficiency gas furnace would save about $160 a year to run in Marshall County compared with a gas furnace.

West Virginia requires HVAC contractors to hold a state license.
The license is issued to the contractor, not to this particular job. West Virginia tested the contractor and keeps a record of them through the Commissioner of Labor before they can take on work like a furnace installation.
In most cities and counties, a furnace installation also needs a permit from the local building office, with an inspection once the work is done. That inspection is separate from the state license and covers the installation itself, including the gas connection. More than half the homes in Marshall County heat with gas, so that connection is not unusual here.

- What size furnace does my house need?
- It depends on your square footage, your insulation, your windows, and how your house is laid out, so there's no single number that fits every home. A contractor sizes it with a load calculation, not a chart based on square footage alone. This matters more here than in milder places, since winter lows average 24°F and homes need heat from October through May. A furnace that's too small will run constantly and still fall short on the coldest nights. One that's too big will short cycle and wear out faster. Have a contractor run the calculation for your specific house.
- How do I know it's time to replace my furnace?
- Start with how often it's breaking down. If it needs a repair more than once a season, or a repair would cost a large share of what a new furnace costs, replacement usually makes more sense. Rising gas bills with no other explanation can mean the heat exchanger or burners are losing efficiency. With heat needed here from October through May, a furnace that's struggling has to get through eight months of the year, not just a few cold weeks. If it's already failing, that's a long stretch to rely on a unit you can't trust. A contractor can look at its condition and tell you whether repair still makes sense.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and how much you're paying now to heat it. High-efficiency furnaces recover more heat from the fuel they burn, so less of it goes out the vent, and that matters most where the heating season runs long. Homes here need heat eight months a year, with winter nights averaging 24°F from December through February, so a furnace here runs far more than one in a mild climate. Since November 2015, new non-weatherized gas furnaces have had to reach at least 80 percent AFUE, and high-efficiency models go well above that. A contractor can walk you through the options and what fits your house.
