Mason asks a lot of a furnace
Mason needs heat from October through April, seven months of the year. Winter nights average 25°F, and 53.2% of homes here heat with gas. A furnace installed now has to hold up through that whole stretch, not just the coldest weeks.
Any new non-weatherized gas furnace has to reach at least 80 percent AFUE. That's a federal floor, not a local one. Warren County has logged 14 winter storms and 142 damaging wind events over the past ten years, and in Ohio, 18% of households went at least 24 hours without power in 2024. A furnace put in right is one less thing to worry about when the weather turns.

In Ohio, HVAC licensing for homes is left to the counties.
Ohio leaves this to the counties, so whether a contractor here needs a license depends on Warren County's own rules, not the state's. Ohio does set one statewide definition. A home contractor has to carry at least $250,000 in liability insurance. That is a floor for coverage, not proof anyone tested the contractor's work.
For a furnace installation, the protection that usually reaches into your house is the permit. In most cities and counties a new furnace needs one, along with an inspection once the work is done. That is what stands behind the job in place of a state license, since Ohio has none for this work. More than half the homes in Warren County heat with gas, which is worth knowing when you think about what that inspection is checking.

- What size furnace does my house need?
- A contractor has to run a load calculation to answer that, one that looks at your square footage, insulation, windows, and layout. Going by square footage alone gets it wrong often enough that it's not worth guessing. A furnace that's too big cycles on and off too fast and never runs long enough to heat evenly. Too small, and it runs constantly on the coldest nights and still can't keep up. With winter nights here averaging 25°F, getting the size right matters more than it would somewhere milder.
- How do I know it's time to replace my furnace?
- Age is the first thing to check, along with how often you're calling for repairs. Once a furnace is old enough that repairs are becoming frequent, it's worth asking a contractor whether the next one is worth doing. Watch for rising gas bills without a change in how you use it, rooms that heat unevenly, or a furnace that short cycles or takes longer to warm the house than it used to. Homes here need heat from October through April, seven months of the year, so a furnace on its way out will show it fast once the cold sets in. A contractor can tell you whether what you're seeing is worth fixing or worth replacing.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and what furnace you have now. Every non-weatherized gas furnace made since November 2015 already has to reach at least 80 percent AFUE, so the question is what a higher-rated model would add on top of that baseline. The higher the rating, the less gas is wasted as exhaust instead of heat. Winters here run seven months, October through April, so that difference in fuel use has a long stretch to add up. A contractor can walk through the actual models and what each one would mean for your house.
