How Many Hours Should Your AC Run Per Day?

In the summer heat, an air conditioner can be a lifesaver, however, running an air conditioning unit all day is more expensive. To save money and keep cool in the summer, you may want to know how many hours a day your air conditioner should run.

It’s normal for an air conditioner to be on all day long. Determining how long an air conditioner takes to reach your desired temperature setting is the first step in determining the number of hours an AC should run per day. HVAC Service in Alpharetta can help you with this.

How Long AC Can Work in A Day

Typically, an air conditioner should run for about 20 to 25 minutes until it reaches the desired temperature and then turn itself off and recycle throughout the day and night. An air conditioner should run for 10 to 15 hours a day in a perfect situation on typical summer days. 

Aside from your home’s insulation, your location’s climate and the type of air conditioner you use influence how quickly your system reaches the desired temperature.

Your air conditioner should run less frequently when the weather is milder. A properly sized and functioning air conditioner will run in fifteen-minute cycles in mild weather. If your air conditioner is constantly running, it is wasting energy and increasing your utility costs. Regular maintenance and a properly sized unit can prevent problems with your air conditioner.

Factors Affecting How Long An Air Conditioner Runs

Many factors affect how long your air conditioner runs each day, including the following:

  • Size of unit
    Short cooling periods of less than 15-20 minutes and frequent turning on and off indicate that the AC unit in your home is too large. On the other hand, your air conditioner will have to run all day to keep the temperature at an appropriate level in your home if it’s too small.
  • Weather
    You’ll need to run your air conditioner more frequently if you live in a hot climate rather than in a cold one. To maintain a comfortable indoor temperature in hotter climates, run your air conditioner for 3 to 4 hours daily.

  • Insulation
    With proper insulation, the air in your home will stay warm in the winter and cool in the summer. Your AC unit will run more frequently if your home has poor insulation than if you have better insulation. Checking for proper ventilation and adding additional insulation, if necessary, are great ways to determine if your home has poor insulation.
