Answer:  Because they get dirty!

• Does anyone in your home have allergies, asthma, or other respiratory problems?
• Does anyone in your family suffer from headaches, nasal congestion or other sinus problems at night or in the morning?
• Is there a smoker in the house?
• Do you have dogs, cats or other pets in your home?
• Do you notice “musty” or “stale” odors when the heater or a/c is on?
• Do you notice dust on your furniture shortly after cleaning?
• Does it seem like there is not enough airflow coming from your vents?

If you answered YES:

Never cleaning the ductwork is like changing your oil filter without changing your oil. I’m sure you change your furnace filter often – what about everything leading to the furnace filter? Your ductwork can become an unknown breeding ground for fungi, germs, and mold.

Most of all, it causes Poor Air Quality – When air ducts become dirty, your home’s air quality and cleanliness decreases. By keeping the ductwork clean, air quality improves, which helps improve the overall health of everyone living in the home.
