Five months of Henderson County summer heat
Your air conditioner runs May through September here, five months of afternoons averaging 87°F. That's five months of steady work for a new unit to hold up through.
The outdoor unit sits outside through whatever the weather brings. Henderson County has recorded 82 damaging wind events and 9 hail events over the past ten years, with hail up to an inch. If you're installing new, anything built since 2023 has to meet 14.3 SEER2, the federal minimum, so it starts out built for the load these summers put on it.

Kentucky requires HVAC contractors to hold a state license.
The Department of Housing, Buildings and Construction issues that license, and it belongs to the contractor, not to any single job.
For an air conditioner install, that license is what stands behind the work. Most cities and counties in Kentucky also require a permit from the local building office before the job starts, and an inspection once it's done. That inspection is a separate check on the installation itself, apart from the license the contractor already holds.

- What size air conditioner does my house need?
- It depends on more than square footage. A contractor works this out with a load calculation that looks at your insulation, your windows, your ceiling height, and which way your house faces. An oversized unit cools the air fast but shuts off before it pulls the humidity out, so the house feels damp. An undersized one runs constantly and still can't keep up on a 87°F afternoon. Get the calculation done rather than going by the size of the unit you had before or what a neighbor's house uses.
- Should I replace the whole system or just the outdoor unit?
- In most cases you replace both together. The outdoor condenser and the indoor coil are matched to work at a specific capacity and efficiency, and pairing a new condenser with an old coil usually means you lose the efficiency gain you paid for, sometimes voids the warranty, and can shorten the life of the new unit. If your indoor coil and ductwork are recent and in good shape, a contractor can tell you whether they're compatible with a new outdoor unit. If the whole system is old, replacing it as a set is usually the sounder path.
- Do HVAC contractors in Henderson need a state license to work on my home?
- Yes. Kentucky requires HVAC contractors to hold a state license, issued through the Department of Housing, Buildings and Construction. The license covers the contractor as a business, not each individual job. For an AC installation, you'll also likely need a permit from the local building office, with an inspection once the work is done.
