Bowling Green Housing Stock
The median Bowling Green home dates to 1991, according to the Census ACS. That makes the typical house about 35 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Owners live in 37.3% of occupied homes, roughly 11,000 households. Homes here have a median value of $232,100 and households a median income of $48,419. Those two numbers drive the labor adjustment in our estimate.
Between 2020 and 2025, NOAA's Storm Events Database logged 8 hail days and 28 days with damaging thunderstorm winds in Warren County. The largest hail reported was 2.75 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage. Warren County also had 5 tornado days in that period.

Kentucky Permits, Efficiency Rules and Rebates
Kentucky is in the DOE's Southeast region, where new split central air conditioners need at least 14.3 SEER2 (13.8 SEER2 for systems of 45,000 BTU/h and up). Expect the contractor to pull a mechanical permit for a replacement job in Bowling Green. If a bidder suggests skipping it, move on. Also ask for a Kentucky license or registration number and proof of insurance. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- Multi-zone systems cost more per room, but they run off a single outdoor unit.
- Rinse the indoor filters once a month during heavy use.
- If winter nights regularly drop below 10°F, pay for a cold-climate model.
