Seven months of heat, most winter nights near freezing
Bowling Green needs a furnace from October through April, seven months of the year. On winter nights, the temperature averages 29°F, so the furnace is doing real work most nights of that stretch, not just on the coldest ones.
56.5 percent of homes here heat with electricity, and the power does not always stay on through a winter storm. Warren County has seen 11 winter storms and 98 damaging wind events over the past ten years, and in 2024, 24 percent of Kentucky households went at least a full day without power. If you are installing a gas furnace, any unit built since November 2015 has to reach at least 80 percent AFUE by federal rule, so that efficiency floor is already built into what you can buy.

Kentucky requires HVAC contractors to hold a state license.
Kentucky licenses HVAC contractors through the Department of Housing, Buildings and Construction. The license belongs to the contractor, not to any single job, so it covers the person or company doing the work rather than this particular furnace install.
For a furnace installation, that license is what stands behind the work, but it is not the only check here. In most cities and counties, replacing a furnace needs a permit from the local building office before the work starts, and an inspection once the new furnace is running. That inspection is what catches a bad gas connection or a venting problem before it becomes dangerous. The license tells you the contractor was tested by the state. The permit and inspection tell you whether this job, in this house, was done right.

- What size furnace does my house need?
- It depends on your square footage, your insulation, your ceiling height, and how many windows the house has, so there's no number that fits every home. A contractor works this out with a load calculation, not a chart based on square footage alone. Too big and the furnace short cycles, heating the air fast but never running long enough to feel even. Too small and it runs all day on the coldest nights and still can't keep up. Winter lows here average 29°F and homes need heat from October through April, so getting the size right matters more than it would somewhere milder.
- How do I know it's time to replace my furnace?
- Watch for rising repair bills, uneven heat between rooms, and a furnace that runs longer to hit the same temperature it used to reach quickly. If yours is cycling on and off more than it used to, or making noises it never made before, have a contractor look at it before it fails. Homes here need heat from October through April, seven months a year, so a furnace that fails partway through that stretch leaves you without heat when you need it most.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and what you're paying to heat it now. Any gas furnace built after November 19, 2015 has to reach at least 80 percent AFUE, but high-efficiency models go higher, which means less fuel lost out the vent. A contractor can walk through the numbers for your specific house and tell you what the difference would mean for you.
