Should I turn off the air conditioner when leaving the room?

Question

What period of time needs to elapse to make shutting the AC off more efficient than letting it run? I live in a very hot and humid tropical climate.

Can you recommend a formula to calculate this or maybe a site online that might have a calculator?

Answer 1

Do not turn it off when you leave the house (I assume you don't have an AC in each room unless your house has seals between each room, since the air and circulation would be common), but turn it up a bit, say 6 - 10 degrees. This will keep your home at a cooler temperature than it is outside, and still make the recovery time short.

Answer 2

It depends on how much money you can afford to spend on your electric bill & just how cold you want your room to be. If it is an energy efficient or energy saver model, then it is most likely going to be better to leave it on. I turn mine off at night for a few hours, then wake up once I'm hot, and turn it back on. I worry more about overloading the old wiring in my building, rather than a time period & leaving the room.

Answer 3

i could think of an infrared sensor (no longer action sensor) could be a sturdy determination. as long as a heat physique is interior the room, the sensor can administration a contactor/relay than activates/off the AC. you would be able to get courtroom situations that the AC isn't working. they could say that they left the AC on and the room isn't cool whilst they back (it is not). it is going to take some layout engineering artwork to get one that is stable. Or the sensor can change to a 2nd thermostat set to 85F that's no longer settable with the aid of the customer. i do no longer think of you genuinely need to permit the room to get too heat and humid - mould issues could desire to alter into an argument. yet another determination is to easily only can charge extra. $40 9/night vs $4 hundred/night is a extensive distinction. you may in all possibility double your fee and not consequence your earnings in any respect. yet i individually don't understand how your centers learn with the $4 hundred/night ones.

Answer 4

If you're interesting in maximizing energy savings, you SHOULD turn the air conditioner COMPLETELY OFF when leaving home.

Simple laws of thermodynamics, my friends. You might want to revisit your high school physics textbooks.

Answer 5

when you leave for a while,turn it up.It takes more energy to cool the room back.If you are gone for several day's ,go ahead and shut it off.
If you are going to be out for a while give the key to a person you trust and ask them to turn it on for you several hours before you get home so it won't be too hot for you.
If you have ceiling fans,keep them going.

Answer 6

If you turn it off and your place gets heated again, then it takes twice as long and much more electricity to get it started again.
If you are away during the day,keep it at a higher temperature, and then lower it when you get home.

Answer 7

Don't turn it off....u can turn it to a lower setting if you will be gone for a while. If you turn it off, it will take that much more energy to get the room re-cooled.

Answer 8

Leave it on, just at a higher temp. when you leave the house and return later; It takes more energy to cool a house when you turn off and on again than you just leave it on on a higher setting. If you go on vacation and no one will be at the house, turn it off.

Answer 9

It doesnt matter if you turn it off and on, when you come home, and it is hot iside the room, the ac will just have to work harder to cool it down!

Answer 10

Dont turn it off when u leave the room, but when u leave the house altogheter
