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).

Why do do this? Air on means close windows.

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... :)

Even if you close the vents, their is still an air return in your room (usually) and the Central HVAC system sucks air in from all the air returns, that's how it circulates and filters air through the house.
If you close the vents in your room cold air isn't coming into your room, but air is still being sucked in from your room. Because the AC is on and vents are open in other rooms that means the hotter air from your room will be circulated via the intacts into the rooms where the AC vents are open. This drives the temperature up in the other rooms causing the AC to need to kick on again and go in an endless cycle.
To completely close off your room you need to close the exhaust vents and the intakes.
Of course if your room doesn't have an intake and say its in the hall out side of your room, then it should be fine, assuming the door is well insulated (and is usually not the case). Most interior doors are hollow and just visual privacy barriers made of really cheap wood.
My advice, if you want fresh air, go outside.
Not only are you causing havoc on the AC (causing it to work harder than it needs to) you are sucking bringing outside alergies in the house which will clog the HVAC systems air filters faster than they normally one. So you are costing your roommate/landlord etc money in filters, electricity, and wear and tear on the Condensor unit and if the condensor fails thats 4,000-8,000 out the door for a new HVAC system...
As the owner of my property renting it out, if I had a roommate doing this, I would give them three warnings and then I would evict them. Rent does not cover $600 electric bills and early replacement of HVAC systems. I bought my house because it has central AC/Heat, and I want to use it, always, air filtration system and all. As such I would only accept a roommate that shares that desire and window opening policies would be written in the lease so that it would be a breech of contract to have windows open with the AC running or Heat running.
The only time I open a window is if I am painting, or cleaning and need to fumigate a room quickly. If I want fresh air I go outside. If I'm working on my computer and want fresh air I take my laptop outside and sit on the front porch on WIFI.

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.

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....

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.

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

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

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.
