Evansville Weather and HVAC Load
In a normal year, Evansville racks up 3,882 heating and 1,771 cooling degree days (NOAA 1991-2020 normals). Neither season dominates in Evansville. That balance is a big reason heat pumps and dual-fuel systems sell well in Indiana. Count on roughly 68 nights below 32°F and 57 afternoons past 90°F in a typical year. Snowfall averages about 11 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 50,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

Evansville Housing Stock
Census figures put the median build year in Evansville at 1960, so a typical house here has about 66 years on it. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. About 28,000 households here own their home, 53.9% of the occupied total. The median home value is $129,100, and median household income is $52,251. We use both figures to adjust labor and pricing for this page.
NOAA storm reports for Vanderburgh County show 8 hail days and 25 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 1.5 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. Vanderburgh County also had 5 tornado days in that period.
When Replacement Makes Sense
- Both the heating and cooling equipment are 15 years old or more
- An old R-22 AC paired with an aging furnace
- Some rooms are uncomfortable, and the energy bills are high
What Moves the Price
- Efficiency ratings: SEER2, AFUE and HSPF2
- Equipment sized to the house and climate
- Permits and electrical work
- Duct repair or replacement
- Furnace plus AC, or heat pump plus air handler
- Thermostat and zoning upgrades
We lowered the national figures about 12% for Evansville 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
- Startup, testing and warranty registration
- Duct connections and sealing
- Removing the old equipment
- A load calculation and system design
- New, matched heating and cooling equipment
Indiana Permits, Efficiency Rules and Rebates
Indiana 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 Evansville. If a bidder suggests skipping it, move on. Also ask for a Indiana 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 duct leakage test. Leaky ducts can lose 20 to 30% of what the system puts out.
- Make every bidder quote the same efficiency ratings, or the prices won't compare.
- Replacing both pieces at once usually costs less than two separate jobs a few years apart.
