Eight months of heat, and winter nights near 21 degrees
Warren homes need the furnace running from October through May. That is eight months of the year, and on winter nights the temperature averages 21°F. A new furnace here has to hold up to a long season, not just a few cold snaps.
Most homes in this area heat with gas, and any non-weatherized gas furnace built after November 2015 has to reach at least 80 percent AFUE by federal law. Trumbull County has seen 9 winter storms and 143 damaging wind events over the past ten years, and in Ohio, 18% of households lost power for at least 24 hours in 2024. A furnace installed here needs to be sized and set up to handle the cold nights it will actually face.

In Ohio, HVAC licensing for homes is left to the counties.
That means whether a contractor is licensed depends on where in the county the house sits, since a city or township can set its own rule instead of the state. Ohio does define what a home contractor is, and that definition includes carrying at least $250,000 in liability insurance, but that is a bar the state sets on paper, not a license or a test anyone passed.
So for a furnace installation, the protection here comes less from a license and more from what happens at the permit office. Most cities and counties require a permit before a furnace gets replaced, and an inspection once the work is done, and that inspector is who checks that the gas connection and venting were done right. In Trumbull County, where 79.8% of homes heat with gas, that inspection is the part of this job that catches a bad connection before it becomes a dangerous one.

- What size furnace does my house need?
- There's no single number that works for every house. A contractor works this out with a load calculation, which looks at your square footage, ceiling height, insulation, window count, and how the house is laid out. Guessing at size, or just matching the old furnace's rating, is how you end up with a furnace that runs too long or shuts off too soon. With winter lows here averaging 21°F, getting this number right matters more than in a milder climate, since the furnace has to hold its own on the coldest nights, not just the average ones.
- How do I know it's time to replace my furnace?
- Watch for repairs that keep coming back, a furnace that can't hold the house at temperature anymore, or one that's simply old. Furnaces here run October through May, eight months a year, so the parts inside get more hours of work than they would somewhere with a shorter winter. If yours is cycling more than it used to, making noises it didn't used to make, or a technician has told you the heat exchanger is cracked, those are the signs that point to replacement rather than another repair.
- 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 sold since November 2015 has to reach at least 80 percent AFUE, so even a standard new furnace is more efficient than an older one. High-efficiency models go higher than that, and with heat needed here for eight months of the year, the difference in gas use shows up over a full winter in a way it wouldn't somewhere heat is only needed for a month or two. A contractor can walk through the actual models and what each would cost to run in your house.
