I have a multiple story home and in the summer it is always hot on the top floor but cool on the lower floor. Can anything be done to correct this problem?
Heat rises and the top floor will always be warmer. Your thermostat is usually on the main floor, and when that area reaches temperature the thermostat shuts off the equipment, whether or not the other floors are the same temperature. In some homes, where enough existing duct work is accessible, a multi-zone system can be installed, enabling independent control on each level off of one piece of central heating and or cooling equipment. Often simple reducting, the addition of manual balancing dampers, or the addition of one or more return inlet air ducts can greatly alleviate the problem.
