A system that has to work both ends of the year
Henderson County asks for heat from October through April, seven months, then cooling from May through September. There is no real break. Winter nights average 28°F, cold enough that a furnace or heat pump runs through most of the night to hold the house steady. Summer afternoons average 87°F, and the same system has to pull that heat back out.
More than half the homes here heat with electricity, so when the power goes out, the heat goes with it. Kentucky saw 24% of households lose power for a full day or more in 2024, and the last ten years brought 10 winter storms and 82 damaging wind events through the area. A new system should be sized and installed to handle both seasons here, not just get through the next one.

Kentucky requires HVAC contractors to hold a state license.
The state license is held by the contractor's business, not issued job by job, so the same license covers this installation and every other job that contractor takes on. It comes from the Department of Housing, Buildings and Construction, which means the contractor has been tested and is on record with the state before they ever get to your house.
On a system swap like this, the license is not the only check. Most cities and counties in Kentucky require a permit for replacing a furnace, air conditioner or heat pump, and an inspection once the work is done. That inspection is what catches a bad gas connection or a return duct put together wrong, the kind of mistake that matters most in an installation like this one.

- When should I replace my HVAC system?
- Replace it when repairs keep coming back or the system can't hold the house at temperature anymore. An aging furnace or air conditioner is most likely to fail on the night or the afternoon you need it most, and here that means a winter night near 28°F or a summer day near 87°F. If a contractor has repaired the same part more than once, or the system runs constantly without catching up, that's the point to stop repairing and start planning a replacement. Waiting for a full breakdown means picking equipment in a hurry instead of choosing what actually fits your home.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes, and there's a real reason for it. A furnace and air conditioner installed together are matched to work as one system, and replacing only one can leave the other running below its rated efficiency, or void the warranty on the new unit. Homes here need heat seven months a year and cooling five, so both halves see steady use and tend to wear at a similar pace. If one is already struggling, a contractor can tell you whether it makes sense to do both now.
- What happens during an HVAC installation?
- A contractor removes the old furnace and air conditioner or heat pump, then sets the new equipment and connects it to your ductwork, gas line or electrical circuit, and the refrigerant lines. The new system gets charged with refrigerant, tested, and checked against the manufacturer's specs before the contractor walks you through it. This work needs a permit from the local building office, so an inspector signs off once installation is done. Kentucky licenses the contractor doing the work, not the individual job, so it's worth confirming that license before work starts.
