It should fit the hole ok as the 14x14 opening has been standard for many years as far as I know. However there are a couple of other things that you should look for.
1. Most air conditioner units have both an upper and lower part. When you purchase an air conditioner you have to order both parts separately. I just did this and found that all brands do the same.
The lower part (fits on the ceiling inside) is not interchangeable between brands. Make sure the air conditioner you are considering has both parts or one can still be purchased.
2. The thermostat and control module(fits up into the air conditioner itself) is not interchangeable between brands either. Make sure the one you are purchasing has one included or can be purchased. You may/may not be able to use the existing wiring in the wall.
3. If your exiting unit is a ducted unit, when you remove it, check that the ducts in the ceiling are well sealed so no cold air can get between them and the rest of the ceiling. I had to use some Eternabond tape to seal mine up well before installing my new air conditioner.
Hope this helps. :)

Edit: Your reply about non ducted was posted while I was uploading my pictures and before I posted. Oh well, maybe the info will be useful for someone else.
