HOW IT WORKS:
In a forced air system, a furnace is used to force air through a system of air ducts to each room of your home or business. Air passes through a filter where dust and other small particles are trapped. A blower unit blows the filtered air through the furnace, where the air absorbs heat. Furnaces may heat air buy using natural gas, propane, oil or electricity.
A furnace can attain the highest AFUE (Annual Fuel Utilization Efficiency), a measure of a gas furnace’s efficiency in converting fuel to energy – the higher the rating, the more efficient the unit.
This system is by far the most common type of home heating and cooling system.
ADVANTAGES OF A FORCED AIR SYSTEM
• Only distribution method that can also be used for cooling
• Air may be filtered
• Air may be humidified
• Air may be dehumidified
• More cost-effective installation
