What’s In Your Air Ducts?

If you aren’t sure what’s in the air you breathe, you may want to have your home’s air ducts cleaned. Here are some tips to determine when to have your air ducts professionally cleaned.

According to the National Air Duct Cleaner’s Association (NADCA), a typical six-room home creates over 40 pounds of dust annually through everyday living. In addition, the typical family generates a great deal of contaminants and air pollutants such as dander, dirt and chemicals. These contaminants are pulled into the HVAC system and re-circulated 50 to 70 times per day on average. Over time, this re-circulation can cause a build-up of contaminants in the air duct work.

There are a few things that the EPA recommends you do to keep your air duct system clean and free of contaminants:
* Use the highest efficiency air filter
* Change filters regularly
* If your filters become clogged, change them more frequently.
* Be sure you do not have any missing filters and air cannot bypass filters through gaps around the filter holder.
* Have your air coils and drain pans cleaned.
* During dust-producing construction or renovation work, seal off supply and return registers. Do not operate the heating and cooling system until the dust has been cleaned up.
* Remove dust and vacuum your home regularly. Use a high efficiency vacuum cleaner or filter bags. Vacuuming can increase the amount of dust in the air during and after vacuuming, as well as in your ducts.
* If your heating system includes in-duct humidification equipment, operate and maintain the humidifier as recommended by the manufacturer.

You may need professional air duct cleaning if:
* You can visibly see built up dirt, dust or dander in your ducts or at the registers.
* You’ve never had your ducts cleaned.
* Dust is blowing out of your vents.
* You smell unusual odors.
* Your heating and cooling unit runs longer than it used to.
* A coil on your cooling system ices up.
* You own pets or if there is smoking in the home.
* Family members suffer from indoor allergies.
* You recently remodeled your home.
