Oak Park Weather and HVAC Load
In a normal year, Oak Park racks up 5,752 heating and 1,111 cooling degree days (NOAA 1991-2020 normals). Heating is the bigger job here, and furnaces and heat pumps in Oak Park put in far more hours than the air conditioner. A normal year brings 106 nights at or below freezing and 20 days over 90°F. Snowfall averages about 39 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 60,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

Oak Park Housing Stock
The median Oak Park home dates to 1938, according to the Census ACS. That makes the typical house about 88 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 60.7% of occupied homes, roughly 14,000 households. The median home value is $456,300, and median household income is $108,026. We use both figures to adjust labor and pricing for this page.
Between 2020 and 2025, NOAA's Storm Events Database logged 27 hail days and 75 days with damaging thunderstorm winds in Cook County. The largest hail reported was 2.75 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. Cook County also had 8 tornado days in that period.

- Your AC needs replacing, and you'd like cheaper heat at the same time
- Energy bills are higher than you want them to be
What Moves the Price
- A ducted system or a ductless mini-split
- Backup heat, either electric strips or a gas furnace (dual-fuel)
- Electrical panel capacity and wiring

Illinois Permits, Efficiency Rules and Rebates
Illinois 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. Equipment replacements in Oak Park generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their Illinois license or registration number and a certificate of insurance with the quote. 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
- A dual-fuel setup keeps your gas furnace as backup for the coldest nights.
- Ask your electric utility and state energy office what heat pump rebates are open right now.
- Make sure the installer sized the system for your heating load, not only cooling.

Heat Pump Installation Questions from Oak Park Homeowners
How much is heat pump installation in Oak Park?
Plan on $7,400 to $18,200, with most jobs near $13,300. Equipment efficiency, house size and the condition of the ducts and wiring decide where your quote falls.
When is the best time to schedule heat pump installation in Oak Park?
Between late spring and early fall. Oak Park averages 106 freezing nights a year, and heating calls spike from November through February.
Do heat pumps work in cold weather?
Yes. Cold-climate heat pumps keep making heat well below 0°F. They lose efficiency as it gets colder, so many homes in cold regions keep backup heat.
How long does a heat pump last?
Usually 12 to 15 years. A heat pump runs year-round, so it needs maintenance twice a year rather than once.
