SmartAC™ Frequently Asked Questions

The SmartAC program is no longer accepting new enrollments for businesses. If you’re interested in enrolling your home in this program, visit SmartAC for residential customers.
  • FREE SmartAC technology and technical support of your air conditioning system as long as you participate in the SmartAC program. If you have a problem with your system, please CALL US FIRST at 1-866-908-4916. We’ll send out a technician who will determine whether the SmartAC device is the cause of your problem. If our technicians determine that the problem is not related to the SmartAC device, we will recommend that you consult your service company.
  • You reduce the likelihood of power outages in your community and throughout California and help the environment—all without sacrificing comfort or control.
  • As California’s population rises, the demand for energy increases. By joining the SmartAC program, you can help reduce your electricity usage when demand approaches capacity. In fact, current SmartAC community members can help keep over 77,000 homes in California powered in the event of an energy supply emergency.*
  • By generating less electricity from fossil fuel plants during peak periods, fewer greenhouse gases are produced and that means cleaner air for all of us.

*Participation in SmartAC reduces the risk and severity of power interruptions in the PG&E service area that may result from an extreme energy supply emergency.

  • Each SmartAC device can receive a signal from PG&E. When demand for energy strains California’s power system, PG&E will activate the SmartAC devices. This action will allow your air conditioner to operate at a slightly lower capacity.
  • The SmartAC program is triggered only during an energy supply emergency and SmartAC devices are activated only during the summer.
  • Participating in the SmartAC program won’t compromise comfort or control. In a recent survey, most SmartAC participants didn’t even notice when activation had occurred.
  • If activation occurs at an inconvenient time, you can opt out for the day, online or via phone at 1-866-908-4916, without penalty.**
  • The SmartAC device is activated only from May 1 through October 31.

**The ability to opt out for the day may not be available in the event of an extreme emergency.

  • You probably won't even notice when SmartAC technology is activated, but you can always opt out for the day without penalty.**
  • Just contact us at 1-866-908-4916 or log in to restore your air conditioner to its previous setting.

**The ability to opt out for the day may not be available in the event of an extreme emergency.

  • If, for whatever reason, you need to end your participation in the SmartAC program, you can call us at 1-866-908-4916 and we will disable your SmartAC device so that it will no longer be activated during a local or state energy emergency.
  • If you decide to rejoin the SmartAC program, just call us to re-activate your SmartAC device.
