Save Money On Your Electric Bill By Super Cooling Your Home

Homeowners in central and southern Arizona are hunting for new ways to cool off when it gets to be 100 degrees or more.


Super cooling your home may be the answer.

(This video from SRP talks about precooling which won’t do as much as super cooling should.)
Super cooling means you are chilling your house at the right time of day during the summer to save money on your power bills.

You must have a time-of-use plan from your utility. These plans offer cheaper rates for electricity at certain hours of the day and higher rates at other times.

SRP (Salt River Project), APS (Arizona Public Service) and TEP (Tucson Electric Power) all have these plans, so sign up for one of them..

Once your plan is up and running:

• Set the temperature on your thermostat to as cool as you can stand it (68 to 74 degrees) during the time when your off-peak or cheapest rates are available. Run it at that setting throughout that off-peak time.

• You’re going to feel super-cool yourself, so put on a sweater or add extra blankets in your bedroom. That’s because, by doing this, you are not just cooling the air in your house; you’re cooling the walls, the furniture, the floors, the rugs and even the clothes in your closet.

• When the high-cost, on-peak hours arrive, move the thermostat back up to the warmest temperature you can stand in the house in summer (maybe 78-80).

• Your house has been so super-cooled by then that you may not get to where you feel uncomfortably warm.

Employing this strategy with a properly-functioning air conditioner will help you beat the heat and feel cooler all summer. Since adopting this plan, some say they managed to cut their power bill between 25 and 33 percent compared with previous summers.

Before employing this strategy you need to make sure your unit is in good working order.

While it feels like gaming the system, APS is on board. “Pre-cooling is part of APS’s plan to educate our customers about how to be energy efficient,” said APS’s DeGraw. “Shifting air-conditioner use to off-peak periods allows customers to take advantage of lower energy costs.”

“It works for us, it saves a lot of money,” said Glen Littell. “Our summers are brutal out here, so we’ll take the savings.”

Littell has been super cooling his home for three years. He cranks his A/C down to 70 degrees during the off-peak pricing time offered by his power company. Then, during the day and during what is considered peak pricing hours, he cranks it up to 80 degrees.

In theory, the air conditioning the air temperature in his home won’t reach 80 degrees until the peak pricing hours have passed, which translate to a lower monthly bill.

“I think our best month was $146 off from the previous year,” said Littell.

Experts say the sweet spot for a super cool home is between 60 to 68 degrees for an average size home. Experts add, if you properly maintain and care for your air conditioning, it shouldn’t cause damage using the super cooling method.

The air conditioner is the No. 1 energy user in your home, and your pool is No. 2. But you need to be mindful of other appliances as well, like the washer and dryer and the pool equipment.
