Adjust the louvers inside the registers on the wall or floor in the room where too much heat/cooling is present so that the registers are partially closed. For example, to get more cooling upstairs during hot summer months, partially or fully close the registers downstairs to force more airflow to the upstairs registers. Another possible solution is a furnace equipped with a variable speed blower motor. These furnaces are designed to overcome airflow problems in a home and will keep the airflow steady all over the home. These types of furnaces also use about 1/3 the electricity of a standard furnace and can save considerable amounts of money in operating costs. An Arzel zoning system is also a possible solution to this problem. Zoning is the controlled delivery of heated or cooled air to a particular area of the home, without heating and cooling the entire home. Temperatures can be set and maintained indpendently throughout the home through the use of multiple thermostats.
