Energy Efficiency Auditing questions, answered by experts

There are a few ways to reduce your electricity bills if you use window AC units to keep cool. Set the unit temperature at least 1 degree higher than it is currently to reduce costs. Keep the unit clean for it to run efficiently. You may want to hire a window AC specialist near you to inspect the unit once a year and keep it in tip-top shape.

Next, check with your local utility company to find out if you qualify for any local rebate programs to offset the cost of this helpful service.

But remember, you'd need enough Powerwalls to power your whole home continuously because a single Powerwall can’t power large appliances for extended periods.

The unit will need to work extra hard to cool the house back off again after all those hot hours.
