What Size AC & Furnace Do You Need in Illinois?
Illinois sits in a cool climate zone, which changes the heating and cooling load for your home. Enter your details for a quick sizing estimate (BTU, tonnage and a recommended SEER2 range).
Actual equipment sizing requires a professional Manual J load calculation. This tool provides a rough estimate for general informational purposes only and is not professional advice, a guarantee, or a quote. Results may not reflect your specific situation. Always confirm with a licensed HVAC professional before making any purchase or decision. See our Terms of Service for details.

HVAC Tips for Illinois
- Schedule professional HVAC maintenance annually for both your heating and cooling systems. Get your AC checked in spring and your furnace or heat pump in fall to ensure optimal performance and energy efficiency.
- Change your air filters regularly, ideally every 1-3 months. Dirty filters restrict airflow, reducing system efficiency and potentially leading to costly repairs and higher energy bills.
- Consider a programmable or smart thermostat to optimize your energy savings. These devices allow you to set schedules and remotely control temperatures, preventing your system from overworking when you're away.
- Don't ignore strange noises or smells coming from your HVAC system. These are often early indicators of a problem that could escalate into a major breakdown if not addressed promptly by a professional.
- Ensure your outdoor AC unit is clear of debris. Keep the area around the condenser coil free from leaves, grass clippings, and other obstructions to allow for proper airflow and efficient cooling.
