A system that runs almost all year here
Elizabethtown asks for heat from October through April and cooling from May through September. That leaves almost no month where a new system sits idle, so it needs to be sized right for both jobs, not just one. Winter nights average 27°F, and summer afternoons average 86°F, so the unit you install has to handle a real swing in both directions.
Most homes here heat with electricity, which means the furnace or heat pump is pulling from the same grid that storms put at risk. Hardin County has seen 17 winter storms and 74 damaging wind events over the past ten years, and across Kentucky almost a quarter of households lost power for a day or more in 2024. A new install is a chance to plan for that, not just for the next cold night.

Kentucky requires HVAC contractors to hold a state license.
The license is issued to the contractor, not to the job itself. It covers the business across every installation they do, and the Department of Housing, Buildings and Construction is the body that tested them and keeps that record.
For this installation, that license is what stands behind the contractor's name on your paperwork. In most cities and counties, replacing a furnace, air conditioner or heat pump also needs a permit from the local building office, and an inspection once the work is done. That inspection checks the installation itself, separate from what the state license already says about the contractor who did it.

- When should I replace my HVAC system?
- Once repairs get frequent or the system is old enough that a breakdown feels like a matter of time, it is worth planning a replacement instead of waiting for it to fail. Homes here need heat from October through April and cooling from May through September, which is 12 months a year of one or the other. That leaves no real off season to put a decision off. A failure during the winter, when nights average 27°F here, is a much worse time to be without heat than a planned swap in the fall.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes, and there is a reason beyond convenience. A furnace and air conditioner installed together are matched to work as one system, and pairing a new unit with an old one can mean it never runs at the efficiency it is rated for. Replacing both also means one visit, one permit, and one inspection instead of two. If only one has actually failed, a contractor can tell you whether the other is worth pairing with now or still has good years left.
- What happens during an HVAC installation?
- The old furnace and air conditioner come out, and the new ones go in and get connected to the ducts, gas or electric lines, and the condensate drain. The contractor sets the refrigerant charge, checks the airflow, and tests the system through a full heating and cooling cycle before calling the job done. In most cities and counties around Elizabethtown, this work needs a permit from the local building office and an inspection once it is finished. The contractor handling the installation should be the one pulling that permit, not the homeowner.
