Henderson County asks a furnace to run seven months straight
Winter nights here average 28°F from December through February, and homes need heat from October through April. That is seven months a year the furnace has to work, not just a few cold snaps.
More than half of Henderson County homes heat with electricity, and Kentucky saw storm-related outages hit nearly a quarter of households for at least 24 hours in 2024 alone. The last ten years brought 10 winter storms and 82 damaging wind events through this area. A new furnace has to hold up through that, and if it is a non-weatherized gas furnace built after November 2015, it has to meet 80 percent AFUE by law.

Kentucky requires HVAC contractors to hold a state license.
The license is issued to the contractor, not to this furnace installation, so it covers who the company is, not the details of the job. Kentucky's Department of Housing, Buildings and Construction is the body that tests and licenses HVAC contractors, and the record of that license sits with the state, not with Henderson County.
For this installation, Henderson County most likely still requires a permit from the local building office, with an inspection once the furnace is in. That permit and inspection are a separate check from the state license, covering the job itself rather than the contractor's standing.

- What size furnace does my house need?
- It depends on your home's square footage, ceiling height, insulation, and window count, so there's no single number that fits every house. A furnace that's too big cycles on and off too often and never runs long enough to heat evenly. One that's too small runs constantly and still can't keep up on the coldest nights, and with winter lows here averaging 28°F, that shortfall shows up fast. A contractor sizes the furnace by calculating your home's actual heat loss room by room, not by going off square footage alone.
- How do I know it's time to replace my furnace?
- An aging furnace is the first clue. As a furnace gets older it works harder to do the same job, and repairs get harder to justify as parts wear out. Watch for rooms that won't heat evenly, a furnace that cycles on and off more than it used to, or a jump in your gas or electric bill with no other explanation. Since homes here need heat from October through April, a furnace that's already struggling early in that stretch usually won't hold up through the coldest nights.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and how much you're currently paying to heat it. Every furnace made since late 2015 has to hit at least 80 percent AFUE, so even a standard model isn't wasteful, but high-efficiency furnaces push well past that and burn less fuel for the same heat. With homes here needing heat 7 months a year, that difference adds up more than it would somewhere with a short winter. A contractor can walk through the actual models and efficiency ratings that make sense for your house.
