I am staying in Chennai, and during the summer, it gets really hot. Currently I have been using the AC for 1 to 2 hours during the day. So I’d like to answer your question: How many hours should AC run per day? Let me tell you that it depends on the size of the AC and the room. Typically, it takes around 15-20 minutes for the AC to cool down a hot room. 

How Many Hours Should Split AC Run Per Day?

The amount of time your AC needs to run depends mainly on two things: the size of your AC unit and the size of the room you're cooling. 

  1. For smaller rooms with a split or window AC, you can usually keep it running for about 8 to 10 hours before it needs a break to cool off. 

  2. On the other hand, bigger wall-mounted units can run up to 12 hours, depending on their power and how much cooling they can handle. 

If you're using the AC for 10 to 12 hours, that's fine, but keep in mind that your electricity bill will also go up as a result. I hope now you know how many hours should an AC run per day.

I used to wonder how many hours should AC run per day, as I feel that using it continuously is simply a waste of power and money. However, I live in Mumbai, and it gets really hot here, so while researching the ideal run time, I found out that 10-15 hours a day during the peak summers is fine. You can go an hour up and around, as the conditions here in India get really hot during the peak April-May time. Apart from this, I am sharing a bit more information I found out about the daily run time for an AC.

How many Hours Per Day should AC Run?

On average, the AC runs for around 20 to 25 minutes till the time it reaches the set temperature. Once the AC reaches this temperature, it turns off and recycles through the day and night. However, this is an average rate, and the time to reach the desired temperature can fluctuate depending on the climate of the place where you live. 

I found that following this 10-15 hour usage period not only reduces the energy consumption, which saves my money due to a lower electricity bill, but it also helps in its maintenance. 

So, If you’re looking to improve the life of your AC, try to follow this. While you do so, time-to-time maintenance would help keep the ACs functioning at par and prevent any serious damage. 

This is all about the average AC run time per day. I hope you find this helpful.
