Five months of cooling in Nicholasville summers
Your air conditioner works five months a year here, May through September, with summer afternoons averaging 85°F. That is the stretch where a unit either holds up or shows its age.
Jessamine County has also logged 37 damaging wind events and 9 hail storms over the past ten years, with hail up to 2.75 inches. Whatever you install needs to be able to take that. If you're installing new, the federal minimum is 14.3 SEER2, so any new central air conditioner has to clear that bar.

Kentucky requires HVAC contractors to hold a state license.
The license comes from the Department of Housing, Buildings and Construction, and it covers the contractor, not the individual job. The state tested and recorded the person or business before they could call themselves a licensed HVAC contractor, but your installation does not get its own separate state license.
For an air conditioner installation in Jessamine County, the local building office is what checks the work itself. Most cities and counties require a permit before the installation starts and an inspection once it is done. The state license establishes who the contractor is, and the local permit and inspection are what stand behind the job done in your home.

- What size air conditioner does my house need?
- The right size depends on your square footage, how much shade and window area you have, your insulation, and your layout, not just the size of the house next door. A contractor works this out with a load calculation, not a guess based on tonnage per square foot. Putting in one that is too big cools the air fast but shuts off before it pulls the humidity out, and Nicholasville summers sit around 85°F for five months, so that moisture matters. One that is too small runs constantly and still cannot keep up on the hottest afternoons.
- Should I replace the whole system or just the outdoor unit?
- If the indoor coil and outdoor unit were installed together and are close in age, replacing just the outdoor unit usually is not the better choice. The coil and compressor are matched to work at a specific efficiency and capacity, and pairing an old coil with a new condenser can mean the system never reaches the rating it is supposed to. New units also have to meet the 14.3 SEER2 minimum that took effect in 2023, and an old coil was not built around that. A contractor can look at the age and condition of both pieces and tell you whether a matched pair makes more sense here.
- Do HVAC contractors in Nicholasville 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. That license covers the contractor as a business, not each individual job. Installing a new air conditioner also typically needs a permit from the local building office, with an inspection once the work is finished.
