June 19, 2020

As the temp increases, so does your air conditioning bills. To keep your air conditioning expenses under control you may be wondering, is it cheaper to leave your AC on all day in the summer in Tucson?

It’s a widespread belief that turning your AC unit on and off throughout the day is inefficient. This is actually false.

Keeping your AC on all day means you’re not using it very efficiently. We recommend moving your thermostat to a higher setting when you’re elsewhere, and lowering it when you return. You can do this with a programmable thermostat. Or, a smart thermostat will do the work for you.

It’s significantly more taxing for your system to keep a consistent temp all day long. It can also lead to a lot of wear and tear to your air conditioner, since it’s frequently turning on and off.

So, on top of it increasing your energy bills, it can also lead to a shortened life cycle for your AC unit.

Regardless, the greater the difference between your house’s temperature and the outside temperature, the greater your AC expenses will be.

In the warmer months, it’s recommended to set your thermostat at 78 degrees while you’re home and 88 degrees when you’re away. It’s additionally important to avoid setting your thermostat to a colder setting than normal when you turn on your air conditioner.

While these temperatures may appear high, there are a number of approaches to keep comfortable without having to constantly run the AC unit.
  2. Use Fans, Curtains and Blinds. ENERGY STAR says raising the thermostat by just 2 degrees and turning on your ceiling fan can lessen air conditioning costs by up to 14% throughout the summer. It’s important to keep in mind that fans cool people, not areas. So, when you exit the room, turn the fan off to be energy efficient. Furthermore, keeping blinds low and curtains closed for the duration of the day helps keep cool air in. There are also some window treatments designed to deliver extra insulation and enhance energy efficiency.
