Orland Park Housing Stock
Half the homes in Orland Park were built before 1988 (Census ACS median), so the typical house is about 38 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. About 20,000 households here own their home, 86.2% of the occupied total. With a median household income of $98,979 and a median home value of $349,400, local labor rates come out above the national middle in our model.
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. In Orland Park, 24.1% of residents are 65 or older. For older adults, a house with no heat in January or no AC during a heat wave is a medical risk. Mention it when you call, since many companies put those calls first.

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 Orland 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
- Rinse the indoor filters once a month during heavy use.
- If winter nights regularly drop below 10°F, pay for a cold-climate model.
- Multi-zone systems cost more per room, but they run off a single outdoor unit.
