Have you Heard of Super Cooling?
Super Cooling is a great way to choose when you use power to cool your home, and can save you up to 30% on your electric bill. Whether your utility company is SRP or APS you have the ability to get on a time of use plan. With these plans your electricity cost per Kwh changes depending on the time of day you are using it. Using electricity during the peak hours means you are paying up to three times as much as you would be if you were using the same amount of electricity during the off-peak hours. Peak hours are the hours of the day when electricity demand is at its peak. This is generally between 2:00pm and 8:00pm weekdays. Unfortunately those are also the hours when there is the greatest demand for cooling off your home. Since most of us can’t stand the 100°+ heat without air conditioning, the next best thing to do is to transfer the electricity usage necessary to keep your house cool to the off-peak hours. That is where super cooling comes into play. The idea of super cooling is to run your air conditioning unit during the off-peak hours to get your house as cold as you can stand it. During the peak hours turn up your thermostat so that your air conditioning unit doesn’t turn on, or doesn’t turn on as often, during those hours.
Is it Good to Run My System For that Long?
Running the AC continuously for hours is counter intuitive for those who are budget- and energy-conscious, but this is one of the greenest things you can do. “I get a lot of pushback: ‘You’re just gobbling up power!’ Yea, but I’m gobbling it up when the power company can’t do anything with it. Once electricity is made, you can’t put it in a gas tank and store it,” he said. “If we can take the peak off the afternoon summer load, it’s going to keep us from having to build another power plant for decades. We build power plants to meet summer afternoon peak loads. And then the rest of the time we’re dealing with excess capacity.”
Here is How we Super Cool our Home.
- We set our thermostat to start cooling, at the beginning of the off-peak hours typically 8:00pm, to the temperature we are comfortable sleeping at, for us that is 76°.
- We then set our thermostat to start super cooling our house in the morning at 8:00am, we set it for 68°. Your unit will be running for a long time to get it down to that temp, but don’t worry, remember you are paying 1/3 as much for your electricity, and running the AC continuously is easier on your system than the on-again-off-again of trying to maintain a steady temperature all day.
- Next we set our thermostat temperature to change to 80° at 2:00pm, when peak hours start. Depending on the insulation in your home, how frequently people are going in and out, if you are using your heat generating appliance, stove, oven, etc, and if you have your blinds and shutters open, your AC unit may not turn on at all during the peak hours, or at the least you will have reduced the number of times your unit kicked on, saving you money.
- At 8:00pm our thermostat goes back down to 76°, starting the cycle all over again.
