Recent research has revealed the answer. It’s not as simple as a “yes” or “no”. It all depends on many factors, including the type of air conditioner that you have.

While summer may be over, many areas of the country will still require air conditioning throughout the fall. You may be thinking about utility bills and wondering “What is the best way to use my air conditioner?”

All three engineers at the University of Colorado were able to test whether turning off the air conditioner during the day saves money. Their study found that it all depends on the amount of energy required to heat your home.

There are many factors that can influence how your home is insulated. These include your climate, the type of AC unit, and how much insulation you have. Your home’s insulation will reduce heat loss during the day. This will lower the AC’s load. The humidity and type of your AC also play a role.

Researchers looked at three climates, three systems, and three cooling cycles. They also standardized the time of the day, including the hottest. They also used accounting to account for different experiences.

Surprisingly, not all air conditioners are the most efficient. Different factors may impact your particular situation. The general answer is yes.

You can save energy by turning off the AC for eight hours. This applies to all types of systems. It produced mixed results if it was left on for four hours. It could save some energy depending on the humidity or use a lot more energy than running it continuously for four hours.

The cleanliness of the system was not something the study considered. An unclean air conditioner will not cool as well. To keep your unit running well, make sure to clean it regularly.
