When we leave our homes for the day, the air heats up and stagnates. This hot air rises and expands, making the home uncomfortable and preventing cooler air from entering.
During hotter days, in-home temperatures can reach 100 plus degrees. Hot expanding air also accounts for the difficulty in using small fans to blow cool air into the home as these fans lack the volume of air movement needed to rid the home of heat.
Some homes have hot zones or specific areas where there is inadequate air circulation for reasons such as not having windows, a window that faces the afternoon sun, having a poorly constructed ceiling or the lack of a cross-breeze.
