Heating and Cooling Distribution Systems
The distribution systems for your furnace and air conditioning system include the duct work, the hot air return and the vents. Ducts connect the furnace to floor or sideboard registers in each of your rooms, and a blower delivers heated or cooled air to your living space.
These distribution systems are subject to several problems. Ducts that are improperly connected can cause less heat to reach your rooms. In addition, improperly installed ducts can be a source of mold and mildew and can send those allergens all over your home. The inspector will also check to see that your ducts are properly insulated and hung or supported correctly.
