by Diane Barnes

Pollutants can enter your home in a variety of ways, including your air ducts. Though scientists aren't sure about whether or not dirty air ducts pose any direct health risks, there are nonetheless quite a few reasons why you might want your air ducts cleaned. Check out these four great reasons below to decide whether or not your home is due for a duct cleaning.


If there is a substantial amount of mold that has grown inside your air ducts, you should consider having them cleaned. There are, however, a couple of things you should keep in mind.

First, not everything that appears to be mold actually is mold. Have substances confirmed as mold by a laboratory before deciding to spend hundreds of dollars on duct reinstallation. Also, if the mold has grown on insulation materials, you will need to rip out and replace all of the affected area.


Sometimes various vermin choose to make their home in air ducts. Those most common kinds of vermin include small rodents such as mice and rats, and insects such as cockroaches. If an inspection confirms that a number of pests have been getting a little too comfortable in your air ducts or near your heating and air conditioning units, have them exterminated and removed from the ducts as soon as possible.


Ducts that have mold or vermin are fairly major problems that don't occur too often. Much more common is the experience of cleaning the duct registers only to find that a substantial amount of debris, such as dust or pet hair, is floating through or clogging the register. Though these kinds of debris have not been conclusively shown to pose any significant health risk, you may still want to have your air ducts cleaned to improve the quality of the air inside your home.

Home Renovation

Remember, a big part of keeping your air ducts clean is preventative. Even if you know your air ducts are presently clean, don't forget to seal them off during a home renovation. If you're renovating an older building and haven't properly sealed the air ducts, it may be the case that lead paint or asbestos particles can float up into the ducts and settle there. If you know that a renovation has occurred shortly before you moved in, try to obtain confirmation that the air ducts were sealed during the entire process.
