Overland Park Weather and HVAC Load
In a normal year, Overland Park racks up 4,957 heating and 1,382 cooling degree days (NOAA 1991-2020 normals). Heating is the bigger job here, and furnaces and heat pumps in Overland Park put in far more hours than the air conditioner. Count on roughly 98 nights below 32°F and 34 afternoons past 90°F in a typical year. Snowfall averages about 14 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.

Overland Park Housing Stock
The median Overland Park home dates to 1989, according to the Census ACS. That makes the typical house about 37 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. About 51,000 households here own their home, 61.5% of the occupied total. The median home value is $384,400, and median household income is $103,838. We use both figures to adjust labor and pricing for this page.
NOAA storm reports for Johnson County show 20 hail days and 35 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 3.5 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. Johnson County also had 3 tornado days in that period.

Kansas Permits, Efficiency Rules and Rebates
Kansas falls in the DOE's North region. New split central air conditioners must meet at least 13.4 SEER2, and heat pumps sold anywhere in the U.S. need 14.3 SEER2 and 7.5 HSPF2. Expect the contractor to pull a mechanical permit for a replacement job in Overland Park. If a bidder suggests skipping it, move on. Also ask for a Kansas 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
- Ask for a heat-loss calculation. A lot of old boilers are much bigger than the house needs.
- A combi boiler frees up space and replaces your water heater.
- Ask your gas or oil company about rebates on condensing boilers.
