When You Are Not At Home Should You Turn Off Your Air Conditioner?


Like most homeowners, you would assume that the best way to save money on cooling costs is for you to turn your air conditioner off when you are not at home.

However there is a much better way to save money, and that is to actually turn your thermostat up instead of turning the AC completely off.

More specifically, we at HVAC Philly, suggest turning the set temperature up 7 to 10 degrees while you’re away for the day.

How could turning up the thermostat possibly be the better option?

Three very good reasons:

  • Protects your home from mold and bugs
  • Saves you money
  • Keeps you comfortable

HVAC Philly takes a closer look at these benefits.

Benefit #1: Turning the thermostat up protects your home from mold/bugs

Turning off your air conditioner can cause your home’s indoor humidity levels to rise significantly. There are two disgusting intruders who love humidity, and they are:

  1. Mold
  2. Bugs

The thing is, your air conditioner does not just cool your air, it also dehumidifies it. So when you turn your AC completely off, it won’t take long for the humidity in your home to soar to upwards of 60%, which is ideal for mold growth and bug infestations.

However if you turn the thermostat up 7 to 10 degrees, your air conditioner will kick on every once in awhile to control the indoor humidity and maintain a healthy humidity level between 45%-55%.

Benefit #2: Turning the thermostat up keeps you comfortable

There is no one that loves coming home to a humid and stuffy home. Unfortunately that is what you are setting yourself up for when you turn your air conditioner completely off.

Instead, turning your air conditioner’s thermostat up 7 to 10 degrees will help to manage the indoor humidity and will keep temperatures at a tolerable level.

So that you may stay comfortable and save money at the same time. Which leads us to the next benefit…

Benefit #3: Turning your thermostat up saves you money

Turning up the thermostat 7 to 10 degrees for 8 or more hours a day can save you at least 10% on cooling costs throughout the entire summer.

You may be asking why and how? Simply, when you raise the thermostat, you decrease the difference between the outside and the inside temperature. And that lowers your air conditioners workload, and therefore, saving you energy.

Here is an example of how you might raise your thermostat to save money:

6 AM: You wake up and get ready for work.

7 AM:  You raise the thermostat from 68 to 78 before leaving the house.

6 PM:  You lower the temperature back to 68 when you get home.

Still not sure that you can remember to raise the thermostat every morning? Think about investing in a programmable thermostat, which can change the temperature automatically for you.
