Five months of real heat in Frankfort
Your air conditioner runs May through September here, with summer afternoons averaging 86°F. That is five straight months of work, not the occasional hot week, and the unit has to hold up to it every one of those days.
Franklin County has also logged 51 damaging wind events and 11 hail storms over the past ten years, one leaving hail two inches across. An outdoor condenser sits exposed to that. If you're installing new, it should be a unit built for the running and the weather both. Any central air conditioner built since 2023 has to meet a federal minimum of 14.3 SEER2, so that efficiency comes standard now.

Kentucky requires HVAC contractors to hold a state license.
The license comes from the Department of Housing, Buildings and Construction. It covers the contractor, not each job, so it is tied to the person doing the work rather than to this one installation.
For an air conditioner installation, most cities and counties in Kentucky also require a permit from the local building office, with an inspection once the work is finished. That inspection checks the installation itself, separate from what the license already tells you about the contractor.

- What size air conditioner does my house need?
- The right size comes from a load calculation, not the square footage of your house alone. A contractor looks at your insulation, your windows, your ceiling height, and how much shade your house gets before landing on a number. An oversized unit cools the air fast but shuts off before it pulls the moisture out, so the house feels damp. An undersized one runs constantly and still can't keep up on a 86°F afternoon. Either way, a contractor measuring your actual house is the only way to get this right.
- Should I replace the whole system or just the outdoor unit?
- In most cases, both the outdoor unit and the indoor coil should go in together. They are matched to work as a pair, and putting a new outdoor unit on an old coil usually means you lose the efficiency you paid for. If your indoor coil is old, a contractor may also find it wasn't built to pair with a newer refrigerant or a higher efficiency rating. The only time replacing just the outdoor unit makes sense is when the rest of the system is new enough to still be a proper match, and a contractor can tell you that by looking at both pieces.
- Do HVAC contractors in Frankfort 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 they do. For an AC installation, you'll also likely need a permit from the local building office, with an inspection once the work is finished.
