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.
When Replacement Makes Sense
- The furnace is 15 to 20 years old or more
- A repair quote runs past a third of the cost of a new unit
- Gas or electric bills keep climbing even though usage hasn't changed
- Some rooms stay cold, the burner short-cycles, or the ignitor keeps failing
What Moves the Price
- Permit and inspection fees, which the local building department sets
- AFUE rating: a basic 80% unit vs. a 96% condensing furnace
- Condition of the existing ductwork and any changes it needs
- BTU size, which should come from a Manual J load calculation
- New PVC venting if you move to a condensing model
- Single-stage, two-stage or modulating gas valve
We raised the national figures about 25% for Overland Park using local income, home values and the equipment size this climate needs. Real bids can still come in outside the range, so collect three written quotes.
What the Quote Should Cover
- Removing and hauling away the old furnace
- Combustion and safety tests
- Gas line and vent connections
- The permit and the manufacturer warranty registration
- The new furnace, filter rack and thermostat wiring
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 the Manual J load calculation in writing. Oversized furnaces are the most common mistake we see.
- Make sure all three quotes are for the same AFUE and staging, or you can't compare them.
- Look up utility rebates on 95%+ AFUE units before you buy.

Furnace Replacement Questions from Overland Park Homeowners

Between late spring and early fall. Overland Park averages 98 freezing nights a year, and heating calls spike from November through February.
Is a high-efficiency furnace worth it?
In cold climates, a 95%+ AFUE furnace usually earns back the price difference in lower gas bills. Where winters are mild, the payback can take a very long time.
How long does a furnace replacement take?
A straight swap is usually done in one day, somewhere between 4 and 10 hours. Moving to a condensing furnace with new PVC venting can add a few more.
