How to Save Money on Air Conditioning Costs: Spring and Summer Tips

In the typical Chicago-area home, air conditioning is one of the biggest contributors to electricity bills. During extreme heat waves, cooling can account for as much as 60–70% of your energy usage. While turning the thermostat up a few degrees and using the air conditioner less often are effective ways to save money, there are many additional strategies that can help reduce costs without sacrificing comfort.

Optimize Your Air Conditioner’s Efficiency

1. Clean Your Air Conditioner Coils

Dirty cooling coils force your air conditioner to work harder, reducing efficiency and increasing energy costs. Regularly clean the coils to ensure optimal performance.

2. Replace or Clean Air Filters

Clogged filters restrict airflow, making your system less efficient. Replace or clean air filters every one to three months, especially during peak cooling seasons.

3. Schedule Routine Maintenance

Have a professional inspect your air conditioning system annually. They can check refrigerant levels, test for leaks, and ensure all components are working properly.

Use Smart Cooling Techniques

4. Install a Programmable or Smart Thermostat

Programmable thermostats allow you to set cooling schedules that align with your daily routine. Smart thermostats go a step further by learning your preferences and adjusting settings automatically to save energy.

5. Use Ceiling Fans

Ceiling fans can make a room feel cooler, allowing you to raise your thermostat setting by about 4°F without sacrificing comfort. Remember to turn fans off when leaving a room to avoid wasting electricity.

6. Close Curtains and Blinds

On sunny days, close curtains or blinds to block out heat from the sun. Blackout curtains are particularly effective at reducing heat gain.

7. Cook Strategically

Avoid using your oven on hot days, as it can add unnecessary heat to your home. Instead, opt for microwave cooking or grilling outdoors.

Seal and Insulate Your Home

8. Seal Air Leaks

Inspect windows, doors, and other potential draft points for air leaks. Use weatherstripping or caulk to seal gaps and prevent cool air from escaping.

9. Insulate Your Attic

Proper attic insulation can prevent heat from seeping into your home, reducing the workload on your air conditioner.

Make Long-Term Improvements

10. Upgrade to an ENERGY STAR® Air Conditioner

If your system is over 10 years old, consider replacing it with an ENERGY STAR® certified unit. These systems are up to 15% more efficient than standard models.

11. Install Solar Screens or Window Film

Solar screens and window films can block heat from entering your home, keeping it cooler and reducing your reliance on air conditioning.

12. Landscape for Shade

Planting trees or shrubs near windows can provide shade and reduce your home's heat gain. Just make sure not to block airflow around your outdoor AC unit.
