Pre-cooling for a lower summer bill
aps
If you’re on a time-of-use plan, one of the best ways to lower your summer energy bills is to use your air conditioner less during on-peak hours, when energy costs more. By pre-cooling your home, you can do just that.
On one of these plans? Pre-cooling can help you save.
- Time-of-Use 4pm-7pm Weekdays
- Time-of-Use 4pm-7pm Weekdays with Demand Charge
- EV Overnight Charging 11pm-5am Weekdays
We keep it at 72 other than on-peak hours. During on-peak hours, it stays at 80 and we’ve really saved a lot of money.

How it works
Pre-cooling is a great way to save money in the summer, and it’s easy to do.
On weekdays:
- Cool your home during off-peak hours, when energy costs less.
Set your thermostat a few degrees lower than usual for several hours during the day, giving your home time to get extra cool before on-peak hours start at 4pm. - Bump up your thermostat during on-peak hours.
From 4pm to 7pm, raise your thermostat several degrees. Because you’ve pre-cooled your home, you’ll stay comfortable without having to run your AC as much during on-peak hours, when energy costs more. - After 7pm, you can set your thermostat as you like.
It’s that simple. With many thermostats, you can program a schedule and pre-cool your home automatically.
It works great, and we’ve saved a considerable amount on our bill.

Maintaining your AC helps you save
Your air conditioner is one of the biggest energy users in your home, and extreme temperatures make it work extra hard. Having your AC serviced at least once a year will keep it running efficiently, helping you save on your energy bill.
