We get asked this question a lot, Paul. To save energy while you’re away for the weekend, there really isn’t one answer that fits all because there are a lot of factors to consider. For example, the time of year, location, size and type of home, etc. can all influence your situation.

Here are some suggestions:

  • Close the shades, blinds and drapes to keep the sun’s heat out.
  • Raise the thermostat to 82 degrees or higher when you’re away so you’re consuming less energy. Just remember, it may take a few hours to cool your home back to your preferred temperature when you return.
  • For ultimate convenience and control, you may consider installing a smart thermostat, and preferably one you can adjust from your smart phone. This way, you’ll be able to monitor and control your home’s largest energy user right from your phone – wherever you are, and that can definitely impact your energy bill.

  1. we are very comfortable when the thermostat is set at 78. upon going away for 4 days we set the thermostat at 80. It took over 6 hours of continuous running to get it down to 78. did we save any thing?

  2. Florida is the “sunshine state” with that being said why why are there very few homes with solar energy?
