Covington Weather and HVAC Load
NOAA's 1991-2020 climate normals put Covington at 4,803 heating degree days and 1,125 cooling degree days per year. Heating is the bigger job here, and furnaces and heat pumps in Covington put in far more hours than the air conditioner. On average, Covington gets 102 freezing nights and 27 days above 90°F per year. Snowfall averages about 23 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 55,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

Covington Housing Stock
The median Covington home dates to 1947, according to the Census ACS. That makes the typical house about 79 years old. Many houses that age were built with hot-water or steam heat, and plenty still run cast-iron boilers and radiators. 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.

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
- For a steam system, hire a contractor who works on steam regularly.
- Ask your gas or oil company about rebates on condensing boilers.
- Ask for a heat-loss calculation. A lot of old boilers are much bigger than the house needs.
