There are two things to think about katd. Depending on the materials used when framing your glass/paper items -- mould can be a problem. Textiles, fabric, leather can mould quicker than straight forward matting. This can happen even if you do run the air-conditioning for a few hours everday (all day is a waste of resources I think and very expensive). Things generally do better in a highrise then they do in a house.
Also, since many a/c units here are the 'split' type and wall mounted, there is usually a wall for artwork under the unit -- which is prone to leaking. So it's kind of damned if you do, damned if you don't scenario.
Straight forward canvas without glass is the safest bet. If you are moving here on a temporary asignment, I would consider leaving your most precious works at home, as long as they are well taken care there and if finances allow -- consider some of the wonderful artwork SE Asia has to offer. A win-win scenario
