Covington Housing Stock
The median Covington home dates to 1947, according to the Census ACS. That makes the typical house about 79 years old. Houses that old often still have duct runs sized for an old coal or oil furnace and 60- or 100-amp electrical panels. Both can add cost when new equipment goes in. Owners live in 51.5% of occupied homes, roughly 9,400 households. With a median household income of $58,814 and a median home value of $167,900, local labor rates come out below the national middle in our model.
NOAA storm reports for Kenton County show 3 hail days and 16 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 1.25 inches across. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost.

What Moves the Price

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). Plan on a mechanical permit for most replacements in Covington; the contractor normally pulls it. Before you sign, ask each bidder for their 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
- Most mini-splits qualify for utility heat pump rebates, so check before you buy.
- Rinse the indoor filters once a month during heavy use.
- Multi-zone systems cost more per room, but they run off a single outdoor unit.
