Does running the air conditioner with an open window increase or decrease your electric bill?
Question:My room mate is constantly "lecturing" me about having my bedroom window open while she has the air conditioner on at its lowest setting and how it is driving the electric bill up. I have closed and blocked off all of the vents to my room as well as the door. I did this back at home, my parents never had a problem with it (that I am aware of).
Answers:
Why do do this? Air on means close windows.
increase because you are using the air con and you dont need it.
Neither. Air conditioners with "settings" like the ones you put in windows run at whatever setting you put them on, whether the cold air escapes or not. Now, if your roommate is constantly turning up the air conditioning because they can't feel it, then yes, indirectly, you leaving the window open would affect the bill.
Or if you have a thermostat which senses the temperature in the room and adjusts itself automatically, same effect as your roommate adjusting it. It just depends on where the thermostat is located. If it is right next to your room and the vents are all closed you will still be causing the AC to run more often to cool the rest of the house down, but only a little bit. I would just hand her one dollar every month and say "here's for the damage I've done"!
Why would you want your window open if you have an ac?
if you closed the vents in you room and block the door then the AC isnt cooling your room off so it would be saving energy.
My God. And you are going to college too?
increase, when you run cool air the object is to keep cool air in, when it escapes your air will run more. therefore costing you more
increases because it takes longer to cool the house...
Unless you can completely vaccuum seal your room, you are increasing your electric bill. Closing vents decreases the amount of cold air coming in, but definately does not completely close you off from the path of the cold air. So, you are air conditioning the world by opening your window. Your mom and dad must have just not cared.
I believe it would increase the electric bill, because the cool air is leaving through the window, so it takes more air to actually cool the room. More air = more energy used = more $...
Well an airconditioner cools the air in the house. Having an open window will let that cool air out, causing the air conditioner to work harder to cool the room. Therefore, you'll have a higher electric bill.
Even though you may have the door closed, it can still get get out.
1. Running the air conditioner uses alot more electricity than not running it.
2. Assuming that it is hotter outside than inside, the air conditioner will have to keep running and running because cool air will escape out the window and hot air will come in. Its like you're trying to cool down the whole world's atmosphere.
So the answer is yes, it increases your electic bill.
Running the A/C with the window open increases the electric bill because the thermostat wont register at the correct temp and kick off when it hits the desired temperature. The reason for this is because if your room is hotter than what the thermostat is set at, it is going to cause the unit to keep running because it is trying to cool your room. Therefore, the bill will be higher, because it is running longer and more frequently than it should.. closing the door, and the vent wont do a whole lot, unless your A/C is on what is called a "zone system" but it does not sound like yours is... :)
if all the vents are blocked off and something blocking under neath the door so no cold air can get in, i don't see why you would be affecting her... unless there is a return air vent in your room that would cause warm air to be mixed back into the system air therefore diluting the cold air going into the rest of the house causing the ac to work harder to cool it down.the electric bill is so high because she has the ac set at the coldest, the thing probably never turns off and runs 24/7
Look at like this, with a closed window your area will cool off faster and you can turn the system down or completely off, as if the window is open. what is the purpose trying to cool the inside when you letting the outside air come in? To answer your yes the Electric bill will get more flights than the space shuttle
YES YES YES
If your house has central air conditioning and you perfectly seal off your room from the rest of the house, but don't close the vents in your room, then it has no impact on the electric bill, but your room will be colder than you like. Hence, the need for open windows.
If you close the vent to your room so that the air conditioner is no longer cooling it, then the electric bill will decrease. Similarly, if you don't have central air conditioning, sealing off your room will lower the electric bill, regardless of whether or not your window is open.
any opening will allow cold air from the a/c to escape and yes it will run up your bill in that the a/c has to run longer and harder to maintain the set temp. just shut your vents off and keep your blind/curtains closed over your window... this will keep the room cool without the a/c blast!!
It does increase your electricity bill as your air conditioner needs a closed environment. 1 tonne, 1.5 tonne, refers to the capacity of the air conditioner to cool an enclosed space, without overload. If you operate your ac in an open environment i.e.leaving your doors and windows open, it overloads the ac as it cannot handle that much capacity. The life of your ac too gets shortened and it would start needing frequent extra servicing and repair.
If the outside air temp is affecting the thermostat via your room, then yes. If your room is insulated off from the area where the thermostat control is, then no. If you are in a hot climate though, it is more than likely that it is affecting it in some way shape or form. Warm air always moves into area's of cooler air trying to equalize, and most building aren't all that well insulated, especially interior walls.
ait definitely will increase the electric bill. Even with the vents sealed it will take more to cool the rest of the house. Think of the outside walls as a thermal envelope. The interior walls have no insulation, nor does the interior door. So this interior wall and door rise to the temperature of your room, while the other side is absorbing this heat, it makes the ac work harder to keep this heated wall cooler. Your parents never had a problem with this because they love you, but they still paid more for the energy bill. They just didn't complain about it.
Alright Paris, you're home now, daddy's money works great. you can run the AC all day with the windows open and he'll take care of the bill.
if you leave the window open you will have to leave the ac running longer.because the ac is blowing cool air in and then its just flying right out the open window or door..so make sure you close all the windows and doors so that it cools you room and then when the rooms cool enough it will shut down.its self.
1 more tip:
if the ac thermostat settings are too low.that can cause a high electric bill...because when the setting is very low.the room will soon reach that temprature and after it reaches to that temrature the ac shuts of.and after a few minutes when the temprature goes lower than the thermostat it will come on again.
and that keep starting and stopping can cause a high electric bill.
because ac compressors use a lot of power and electricity to start.and if he has to keep coming on and going of that could cause a high bill...
and leaving the door or windows open you will have to keep the ac running all the time and it still wont cool.enough.
and whats the point of running it to cool the room when your letting hot air in yourself through the window.
i hope this helped..
good luck.hope you get a lower bill next time.take care.have fun.and shut windows and door etc.unless you feel you really need fresh air then open it for a bit.then shut again.
Guess if the vents are closed & room sealed it wouldn't really matter.
You should talk to her about the possibility of not running the a/c and just open the windows.Why open the windows when the a/c is on?Do one or the other.The bill will climb up and up,just like she said.
wow! A lot of answers on this one but it is simple.
With everything blocked off in your room the temperature will get warmer in your room than the rest of the house. The Problem is everytime you open your door to enter the rest of the house the warm air from your room pulls back into the rest of the house adding heat back to the conditioned space thus causing the system to run more to reduce the heat.
"nuff said
why would you run an ac with an open window, it does not make sense,of course you would use more energy.the ac is trying to cool down the air coming in.
im constantly telling my kids to close the door, leave the windows closed when the air is on, its common sense.
Yes it will run up the bill you are letting hot muggy air come in and the air conditioner is working overtime to recycle that air.
Hello
If the room is sealed from the rest of the house there should be no difference and probably cheaper for electricity cause that room isint in the cooling zone
Increase because It will work twice as hard trying to cool outside also sounds weird but i had the same problem i compared prices and it was more when i opened the window.
