Arlington Heights Weather and HVAC Load
NOAA's 1991-2020 climate normals put Arlington Heights at 6,085 heating degree days and 933 cooling degree days per year. Heating is the bigger job here, and furnaces and heat pumps in Arlington Heights put in far more hours than the air conditioner. Count on roughly 122 nights below 32°F and 17 afternoons past 90°F in a typical year. Snowfall averages about 38 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 65,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

NOAA storm reports for Cook County show 27 hail days and 75 days with damaging thunderstorm winds over the six years from 2020 to 2025. 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 Arlington Heights, 19.3% 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.
When Replacement Makes Sense
- 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
- A tech found a cracked heat exchanger, or the CO detector has gone off
- The furnace is 15 to 20 years old or more
What Moves the Price
- New PVC venting if you move to a condensing model
- Single-stage, two-stage or modulating gas valve
- Permit and inspection fees, which the local building department sets
- Condition of the existing ductwork and any changes it needs
- BTU size, which should come from a Manual J load calculation
- AFUE rating: a basic 80% unit vs. a 96% condensing furnace

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 Arlington Heights. 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
- 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.
- Replace it in early fall if you can. A no-heat emergency in January costs more and leaves you fewer choices.
