I'm getting married in a non-air conditioned church in June of next year. The wedding is in Pennsylvania, so while the weather isn't always hot in late June, there's a good chance it could be.
The church sanctuary is about 45 x 120 feet (give or take) so we're looking at somewhere in the vicinity of 5000-6000 square feet. here's the kicker though: the ceiling is about 35 feet high, going up in flat-topped A-frame shape, so the volume of the room is much bigger than it seems.
My fiancee insists that the church be cooled in some fashion. My uneducated idea is to buy a room air conditioner (10,000-15,000 btus), leave it running the entire night before and up until 15 minutes before guests (150 of them) arrive.
I'm thinking the night before should be no warmer than 70, if not more like 60 or 50, so outside heat during the night shouldn't be a concern. In the morning, however, there is a large stained glass window facing due east that I imagine will cause quite a greenhouse effect until 10 AM or so, but after that, the entire building is in the shade of large trees.
Does anyone think my plan of using a single AC unit will work, as long as it's left on for 15 or so hours?
Does anyone have any other suggestions? Thanks!
