10 Ways to Cut Your HVAC Energy Bill in Chicago

1. Upgrade to a Programmable or Smart Thermostat

Setback programming saves 10–23% on HVAC costs according to the EPA. Set temperatures back 7–10°F for 8+ hours while away or sleeping. Smart thermostats like Ecobee and Nest automate this effortlessly.

2. Get an Annual Tune-Up

A well-maintained HVAC system operates up to 30% more efficiently than a neglected one. Annual tune-ups pay for themselves in energy savings.

3. Seal Air Leaks

Drafty windows, doors, and electrical outlets can account for 25–40% of heating energy loss. Weatherstripping, caulking, and door sweeps are inexpensive and highly effective.

4. Add Insulation

Chicago's older housing stock is often under-insulated. Properly insulating your attic to R-49 and walls to R-20 dramatically reduces heating and cooling loads.

5. Use Ceiling Fans Strategically

In summer, ceiling fans run counterclockwise to create a cooling breeze. In winter, switch to clockwise at low speed to push warm air down from the ceiling. This allows thermostat setbacks of 2–4°F.

6. Replace Old Equipment

A 10-SEER AC from 2005 uses twice the electricity of a modern 20-SEER unit. An 80% AFUE furnace wastes 20 cents of every heating dollar. Upgrading pays back in 3–7 years through energy savings.

7. Zone Your Home

Zoning systems allow independent temperature control for different areas of your home — stop heating empty bedrooms or unused floors. Multi-zone ductless systems provide the ultimate flexibility.

8. Maintain Proper Humidity

Humid air feels warmer in summer and dryer air feels cooler in winter. Controlling humidity with a whole-home humidifier/dehumidifier lets you set the thermostat 2–3°F in your favor.

9. Clean Vents and Ducts

Dirty ducts force your system to work harder. Ensure all supply and return registers are clean, unobstructed, and properly sealed at the wall/floor connection.

10. Apply for Utility Rebates

ComEd and Nicor Gas offer rebates for high-efficiency HVAC equipment upgrades. The federal government offers a 30% tax credit (up to $600 for equipment, $2,000 for heat pumps). We help you claim every incentive available.
