Frankfort furnaces work seven months a year
October through April, your furnace is what keeps the house livable. Winter nights average 27°F here, cold enough that the burner is cycling on and off most nights of the week for a good part of the year.
More than half the homes in the area heat with electricity, and storms take that power out more than people expect, 24% of Kentucky households lost power for at least a day in 2024. A new gas furnace with a standing pilot will still light without power. If you're replacing an older unit, any non-weatherized gas furnace built since November 2015 has to hit at least 80 percent AFUE, so that's the floor to expect from a new installation, not the ceiling.

Kentucky requires HVAC contractors to hold a state license.
Kentucky licenses HVAC contractors through the Department of Housing, Buildings and Construction. That license is held by the contractor, not issued job by job, so it is the business that has been tested and is on record with the state, not this particular furnace installation.
For this job, that license is what stands behind the person doing the work. In most cities and counties a furnace replacement also needs a permit from the local building office, with an inspection once the work is done. That inspection is what catches a bad gas connection or a venting mistake, the part of the job that can actually hurt someone, and it happens separately from anything the state license covers.

- What size furnace does my house need?
- It depends on your home's square footage, how well it's insulated, your window count, your ceiling height, and how your house is laid out. A contractor works this out with a load calculation, not a chart based on square footage alone. Guessing high seems safe but it isn't. An oversized furnace short cycles, meaning it turns on and off more than it should, and that wears out parts faster and leaves rooms uneven. With winter lows here averaging 27°F, getting the size right matters more than it would somewhere milder, since your furnace is working hard for real stretches of the season.
- How do I know it's time to replace my furnace?
- Watch for rising repair frequency, especially if the same part keeps giving out or a repair costs a large share of what a new furnace would run. Uneven heat, a furnace that runs constantly without keeping up, or a yellow flame instead of blue are signs something is wrong. Age matters too, and a contractor can tell you where your furnace stands against its expected life. Since homes here need heat from October through April, a furnace that's already struggling is a risk not worth carrying into another winter.
- Is a high-efficiency furnace worth it?
- It depends on how much heat your home actually needs, and here that's real. Homes need heat 7 months of the year, with winter nights averaging 27°F, so a furnace with a higher AFUE rating gets used enough to matter. Every non-weatherized gas furnace made since November 2015 has to hit at least 80 percent AFUE, so even the baseline units sold today aren't inefficient. Higher-efficiency models go beyond that minimum, and whether the difference is worth it for your house is something a contractor can lay out once they know your current furnace, your ducts, and how you use your heat.
