Think about it: Air is the most basic resource for humans to survive. An adult breathes more than 2'000 gallons of air every single day. Over the years dust, dirt and other pollutants collect in your air ducts, on average more than 30 lbs every year. Every time your fan is blowing air through your ducts, besides circulating hot or cold air, it will also circulate these pollutants in your home. This can cause allergies or aggravate respiratory conditions such as asthma.
WHY SHOULD I BE CLEANING MY AIR DUCTS?
HOW OFTEN SHOULD I HAVE THE AIR DUCTS CLEANED?
For your families comfort and well being we recommend that you clean your home air ducts at least every 5 years. This period should be shorter if you live in an area with a higher level of airborne pollutants, such as near or under trees, near a highway, construction site or similar. Also, if you have allergies or have pets you may want to consider to have your air ducts cleaned more often.
