We're trying figure out which would be cheaper. In the past we've run a small unit in our bedroom to keep cool at night, the central is off at this point. Saved us from having to crank the central a little higher. The unit was a little to big so it may not be a good comparison. That unit is now upstairs since our sister is living up there, no central air to the second floor. A small a/c window unit at Walmart runs $89-ish. I would compare kilowatts and all that but our central a/c is so old without hooking up an actual meter probably wouldn't be able to calculate correctly. We usually plan to keep the central off till July unless it hits 100. Anybody with a little insight.. we have a few weeks before we'll think about buying one.
