Nicholasville asks a lot of a furnace
Your furnace runs October through April here, seven months of the year. Winter nights average 27°F, so the burner is cycling on and off most nights of that stretch, not just on the coldest ones.
Most homes here heat with electricity, and Kentucky sees real outages. Nearly a quarter of households in the state lost power for 24 hours or more in 2024, and Jessamine County has logged 13 winter storms and 37 damaging wind events over the past ten years. That is worth knowing when you pick a furnace and how it is installed. Any new gas furnace also has to meet the federal minimum of 80 percent AFUE, so that is the baseline a contractor will install to.

Kentucky requires HVAC contractors to hold a state license.
The Department of Housing, Buildings and Construction issues the license and keeps the record on the contractor, not on any single job. So the credential belongs to the business doing the work, not to this particular install.
For a furnace install, that license covers who is allowed to do the work. The job itself still needs a permit from the local building office in most cities and counties, along with an inspection once the furnace is in. That inspection is what catches a bad gas connection or a venting mistake, the kind of thing that makes a furnace dangerous rather than just broken.

- What size furnace does my house need?
- There is no single answer without looking at your house. A contractor sizes a furnace with a heat loss calculation that accounts for your square footage, insulation, window count, and ceiling height, among other things. A furnace that is too big cycles on and off too often and never runs long enough to heat evenly. One that is too small runs constantly and still cannot keep up on the coldest nights, and winter nights here average 27°F. Ask whoever quotes the job to walk you through the calculation, not just give you a number.
- How do I know it's time to replace my furnace?
- Watch for rooms that will not warm up, a furnace that cycles on and off more than it used to, or repair calls that keep coming back. An older furnace working harder to do the same job is usually burning more fuel to get there. Age matters too. Furnaces built after November 2015 have to hit at least 80 percent AFUE, so if yours is older than that, a newer unit is likely running more efficiently than what you have now. Since homes here need heat from October through April, a furnace on its way out tends to show its problems over a long stretch of the year, not just a few cold snaps.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and what you're replacing. A high-efficiency furnace burns less fuel to produce the same heat, and with 7 months of heating season here, that difference gets used every year, not just occasionally. The tradeoff is a higher upfront cost, which a contractor can price for your specific house and furnace size. If you heat with electricity, which is how 62.6% of households here heat, ask the contractor how furnace efficiency ratings apply to your setup, since AFUE is a gas furnace measurement.
