Dirt, pollen, smoke, pet hair, dust mites and even dead skin accumulates in the ducts and adheres to the duct surfaces and to the furnace and air conditioning components. This accumulation creates the perfect breeding ground for bacteria, mold and other fungi that are sources of indoor air pollution. Every time you turn on either your heating or cooling systems, these contaminants get blown into the air that you and your family breathes.
According to the Environmental Protection Agency (EPA) indoor air is 70% more polluted than outdoor air. In fact, one out of every six people who suffer from allergies do so because of the fungi and bacteria found in their air duct system. It is estimated that poor air quality directly results in one billion of medical costs annually and over $60 billion lost in production and employee sick leave.
Air duct cleaning is a home maintenance that many people overlook. Air duct cleaning is not required annual for most homes. Generally this service should be performed on average every five years. Duct cleaning can preserve the life of your heating and cooling systems and at the same time making those systems more efficient. Increased efficiency and longer lasting equipment means decreased heating and cooling costs for the homeowner.
