Window A/C Units Average Cost a month?

Hi. I live in Maryland, and I recently moved into a 3 level townhouse that does not have the duel zone A/C unit. I have the Master Bedroom upstairs, but my roommate and her baby have the basement. It's only been a week and we are all already fighting over the temperature of the A/C. The other day she had it cranked up to 75 degrees because the basement gets so cold. My room in turn was boiling. I prefer it cooler, but can deal with warm rooms, but that was beyond what is comfortable. She doesn't do space heaters, so my only option now is for a window A/C unit. I wanted to know if anyone can give me a ballpark figure on how much that will add to our electric bill? I live in Maryland, so our summers can get hot and sticky. If she leaves the house set at 75, would our costs go up even more? I know it's hard to pinpoint the exact cost, but any ballpark figure would be extremely helpful.

Ballpark, about 15 cents an hour x 10 hours = $1.50 a day


$1.50 x 30 days = $45 a month
Reply:Last time I used one, it cost me about $25 a month.
