Turn your AC system off when you are not home! Even better, get a smart thermostat like the NEST, EcoBee, or Lyric, and let it handle the scheduling.

The Details

I am asked this question a lot and, more often than not, I receive the wrong answer; that it is more economical to leave your air conditioning on when you are not home. Think of it this way.

Imagine, for a moment, that you have a fish tank in your living room with massive leaks on all four sides and the bottom (it was dropped by the movers).

Would you then keep that fish tank full of water while there weren’t any fish in it? Of course not! The more full the tank is with water, the quicker it leaks out due to the higher pressures present. The total quantity of water that leaks out in this analogy is directly related to the amount of wasted energy.

When applying that to your home, you also have other issues to consider. Most of us work close to a 9-5 work day, which means that we are not home during the hottest portions of the day. Therefore, why would it make sense to run your air conditioner during the hottest time of the day, when temperatures are the highest, just for it to be leaking out all day at an expedited rate? (Higher temperatures create higher pressures.)

More Electricity = More Wear And Tear

In addition to the increased electrical consumption, you are also subjecting your HVAC equipment to unnecessary wear and tear, that ultimately reduces your HVAC system’s lifespan. You are better off across the board, if you turn up your AC systems thermostat while you are away, and turn it back down when you arrive home. Or, even better, have it programmed to come on before you arrive. To take this even further, let technology do the work for you by upgrading to a smart thermostat by Ecobee, Nest, or Lyric.

If you ask me, “is it more economical to leave air conditioning on?”, I say turn it off. And both mathematics and physics agree! Save electricity, save money, and save yourself from expensive HVAC repair bills; move up your thermostat to 80 to 86 degrees when you are not home.
