Why Clean Air Ducts: Is it Necessary?


Parents are concerned about the health of their kids.  Employees are concerned about the conditions in their work environment.  A week doesn’t seem to pass without a TV special or talk show presenting medical facts about the dangers of pollutants in the indoor air we breathe.

This brief overview is offered to help you determine if a professional air duct cleaning would be beneficial for your home and family, or workplace.

What’s in Your Air?

The contamination shown on the left is the normal by-product of living things occupying closed spaces.

Skin cells, mold, dust, dirt, mildew, pet dander, aerosol sprays, glue, paint, cooking oils, insecticides, and mouse feces are just a few of the contaminants that float in the air inside our homes or offices.

But, there’s another problem. It doesn’t stay in the air.

These particles settle and find a hiding place to collect and build into a real mess.

What’s Hiding in Your Ducts?

Over a two to three year span, air ducts become lined with particles of contaminants as they settle inside the system. Organic material (hair and skin cells) can also support the growth of mold and mildew.

These pictures show a buildup that is not unusual for a system left untouched for five or more years.  This blanket of dirt is bad enough as it builds up in the system.

However, it doesn’t just lay there. It finds a way back into your lungs.

Can it Affect Your Health?

Every time the blower fan comes on, a cloud of dirty particle-laden dust blows back into the indoor spaces of your home, completing the dust cycle.

Some studies have found the air we’re breathing inside our homes and offices is far more contaminated than the air outdoors.  More and more evidence links childhood asthma with indoor air pollution.

However, that’s not the only problem.  The blanket of dirt also affects the operation of the furnace system.

Can it Damage the Furnace?

The blower fan, heat exchanger, combustion chamber and air-conditioning coils need to be kept clean.  Overheating, short cycling, air-conditioning coil freeze-ups, rust, and wasted fuel are often the results of this contamination.

With both issues considered, our family’s heath and the maintenance of the heating and cooling system, the safest and most economical choice is to keep the system clean.

What’s the Best Solution?

Get your air duct system cleaned!  Many HVAC companies recommend a cleaning cycle of two years to prohibit the buildup of contamination.  This regular maintenance, not unlike regular oil and filter changes in our cars, keeps the furnace running efficiently and the air fresh and clean.
