Reduce electricity demand on the hottest days of the summer by joining ComEd's Central Air Conditioning Cycling. By enrolling, you can help us better manage our energy resources, and earn credits on your summer electric.
With our AC Cycling program, we offer two device options. ComEd can either install a direct load control (DLC) switch at your home, or you can cycle utilizing an authorized Smart Thermostat.
The DLC switch, which ComEd will install on the side of your home or directly on the air conditioner's compressor panel, allows us to turn your compressor off and on, so it uses less power safely during a cycling event. Your fan still stays on to circulate already cooled air and to keep your home comfortable.
The smart thermostat option allows ComEd to control your thermostat through your home Wi-Fi. Currently, Nest is the Smart Thermostat authorized for the AC Cycling Program by ComEd.
Cycling is only done when needed, and it may occur only on weekdays and for limited periods of time.
It's easy to join. If you own your home and have central air conditioning, you can enroll in ComEd's Central Air Conditioning Cycling.
If someone in your household is home during most of the day or has a medical condition, the 100% option is not recommended.

Both ComEd programs offer summer bill credits and are built upon the customer’s ability to reduce energy usage when energy demand is high. Most customers earn larger bill credits on Central AC Cycling than they would on
Peak Time Savings, but these programs differ in several important ways.
Customers may not participate simultaneously in Central AC Cycling and Peak Time Savings.
