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.

Illinois Licensing and Efficiency Rules
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. Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in Illinois the company should carry a state license or registration. Ask for both.
Before You Hire
- Ask whether the diagnostic fee comes off the repair bill.
- Have the model and serial number from the furnace label handy. Parts get ordered faster.
- If the furnace is past 15, ask the tech to price both a repair and a replacement.
