Count on roughly 133 nights below 32°F and 26 afternoons past 90°F in a typical year. Snowfall averages about 20 inches. On the cooling side, a 2,000 sq ft house here usually needs around 3 tons.

McLean County had 15 hail days and 32 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 2.5 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. McLean County also had 8 tornado days in that period.

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. Expect the contractor to pull a mechanical permit for a replacement job in Bloomington. If a bidder suggests skipping it, move on. Also ask for a Illinois 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
- Most mini-splits qualify for utility heat pump rebates, so check before you buy.
- Rinse the indoor filters once a month during heavy use.
- Multi-zone systems cost more per room, but they run off a single outdoor unit.
