Air-conditioning in individual homes is a fairly new practice in much of NB. Only a few of the new homes have built in Air. 20 years ago luxury apartment buildings didn't have it. And people seem slow in catching on to the idea of using airconditioning. They think it will be expensive to operate, or they regard it with suspicion (it causes colds, it spreads disease, it isn't good for you). Many of these people seldom use the A/C in their cars either. (Don't sit in a draft, my grandmother used to say). But gradually the younger, and better educated people have adopted the idea. Many are getting window, or portable, units. I have a window one built into the wall of my livingroom, and a portable in my bedroom.
