Florence asks a furnace to run seven months a year
From October through April your furnace is the thing standing between your family and a house that averages 26°F on winter nights. That is seven months of work, not a few cold snaps here and there.
Almost half the homes in this area heat with electricity, and Kentucky saw 24% of households lose power for a day or more in 2024. A new furnace installed here needs to hold up to real winter and to storms that take the grid down with it. Fourteen winter storms and 86 damaging wind events hit this area over the last ten years. If you are installing a new gas furnace, federal rules now require it to reach at least 80 percent AFUE, so the unit going into your home starts from that baseline.

Kentucky requires HVAC contractors to hold a state license.
Kentucky's license is issued by the Department of Housing, Buildings and Construction, and it covers the contractor, not each job that contractor takes on. The state tested the person or business behind the license and keeps a record of them.
For this installation, the license tells you the contractor met the state's standard. In most cities and counties in Kentucky, a furnace replacement also needs a permit from the local building office and an inspection once the work is done, and that inspection is what checks the gas connections and venting.

- What size furnace does my house need?
- It depends on your square footage, your ceiling height, how much insulation you have, and how many windows face north. A contractor works this out room by room rather than guessing from square footage alone. Going too big is as much a problem as going too small. An oversized furnace heats the house fast, shuts off, then kicks on again a few minutes later, and that short cycling wears out parts sooner. A contractor will size the unit to your house, not just the neighborhood.
- How do I know it's time to replace my furnace?
- Age is the first thing to check. Furnaces installed new since November 2015 have to reach at least 80 percent AFUE, so if yours predates that, it is burning more gas than it needs to for the same heat. Beyond age, watch for rooms that never get warm, a furnace that runs long stretches without shutting off, or a rise in your heating bills that you can't explain by the weather. With winter lows here averaging 26°F and heat needed October through April, a furnace that's struggling in Florence has seven months to get worse before spring gives it a break.
- Is a high-efficiency furnace worth it?
- It depends on how long your winters run and what you're paying now to heat the house. Homes here need heat seven months a year, October through April, so a furnace that runs more efficiently has a long season to make that back. Just under half of households here heat with electricity, so if you're on gas already, the comparison is between your current AFUE and a higher one, not between fuel types. A contractor can look at your current furnace's rating and your house and tell you what the upgrade would actually mean for you.
