Eight months of heat a year, and nights that drop to 22°F
Wood County homes need a working furnace from October through May. That's eight months of the year, with winter nights averaging 22°F. A new furnace here has to carry that load night after night without a break.
Most homes in the area heat with gas, and any non-weatherized gas furnace built since November 2015 has to hit at least 80 percent AFUE by federal rule. That's the floor, not a feature. Wood County has also logged 79 damaging wind events and 6 winter storms over the past ten years, and 18% of Ohio households lost power for at least 24 hours in 2024. A furnace installed here should be matched to the house and set up to start reliably every time, storm or no storm.

In Ohio, HVAC licensing for homes is left to the counties.
Whether a contractor needs a license to work in Wood County depends on the county and city rule where the house sits, since Ohio leaves that decision to local government. The state's own definition of a home contractor calls for at least $250,000 in liability insurance, but that is a definition written into state law, not a license or a test anyone has to pass.
What actually stands behind a furnace installation here is the permit process. Most cities and counties in Ohio require a permit from the local building office before a furnace goes in, and an inspection once it's done. That inspection is what catches a bad gas connection, the part of this job that can actually hurt someone. With most homes in Wood County heating with gas, that inspection is the check that matters most.

- What size furnace does my house need?
- A contractor has to work this out with a load calculation, not a chart based on square footage. That means measuring your walls, windows, insulation and ceiling height, then figuring how much heat the house loses on a cold night. A furnace that's too big will short cycle and wear out early. One that's too small will run constantly and still lose ground on the coldest nights, which matter here since winter lows average 22°F. Get the calculation done rather than guessing from the size of your old unit.
- How do I know it's time to replace my furnace?
- If your furnace is old and keeps needing repairs, replacing it usually makes more sense than fixing it again. Watch for uneven heat between rooms, a burner flame that's yellow instead of blue, or a furnace that cycles on and off more than it used to. Rising gas bills with no other explanation point the same way. Homes here need heat from October through May, so a furnace that's struggling has to get through eight months of work every year, not just a cold snap.
- 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 non-weatherized gas furnace built since November 2015 has to hit at least 80 percent AFUE, so even a standard model wastes less fuel than an older one might. A high-efficiency furnace burns less gas over a heating season, which matters here since most homes run the furnace eight months out of the year. A contractor can walk through what a higher-efficiency model would mean for your specific house and duct system.
