Should I Turn My AC Off at Night and When I’m Not Home?

Whether you’re a first-time homeowner or have lived in the same house for decades, you’ve likely faced this dilemma: Is it more cost-effective to keep your air conditioner on all day, or turn it off periodically? We’ll explain which practice is more energy-efficient and could save you money each month on your electric bill. (The answer may surprise you!)

How Do Air Conditioners Work?

Air conditioners keep our homes and workplaces cool during warmer months by absorbing heat from enclosed spaces, cooling it, then distributing the cool air throughout the enclosed space. For being such a basic system, air conditioners serve a crucial purpose in indoor safety and comfort.

This three-step guide will help you understand the cooling process in more detail:

  1. Air vents transfer warm air from rooms throughout your home to the AC.
  2. The evaporator coil absorbs the heat and cools it with refrigerant, which is stored inside the coil.
  3. A fan blows the cool air into air ducts, and the air ducts distribute it throughout your home.

Will Turning My Air Conditioner on and off Periodically Waste Energy?

Leaving your air conditioner on all day and periodically bumping up the thermostat setting is more cost-effective than turning the system off when you’re away. Here’s why:

  • Your AC never exceeds the thermostat setting. This means the system won’t run unnecessary—and costly—cooling cycles to maintain a comfortable indoor temperature while you’re not at home.
  • By leaving the system on and bumping up the temperature while you’re away, the thermostat will reach the desired temperature faster than if the system was turned off completely. This process requires less energy to cool your home, thus saving you money on your monthly electric bill.

When you turn off the system while you’re away, it has to work harder to reach the desired temperature once you return home. The AC sometimes requires more energy to complete the cooling process, thus increasing your monthly electric bill. Additionally, your AC system can only remove humidity from the air when it’s turned on. If you turn off the system when you’re away, humidity levels will increase and the system must work harder to remove it from the air. This also increases your monthly electric bill.
