Do You Need Duct Cleaning?



 

Every home is different, so it is typically hard to generalize whether a home needs duct cleaning or not. However, there are ways to determine if duct cleaning would be beneficial for you and your family.

You May Not Need Duct Cleaning if:

  • No one in your household suffers from allergies or unexplained symptoms or illnesses
  • After a visual inspection of the inside of the ducts, you see no indication that your air ducts are contaminated with large deposits of dust or mold (no musty odor or visible mold growth)

It is normal for the return registers to get dusty as air is pulled through the grate. This does not indicate that your air ducts are contaminated with heavy deposits of dust or debris; the registers can be easily vacuumed or removed and cleaned.

You May Need Duct Cleaning if:

  • Family members experience unusual or unexplained symptoms or illnesses that you think might be related to your home environment; you should discuss the situation with your doctor.
  • There is substantial visible mold growth inside hard surface (e.g., sheet metal) ducts or on other components of your heating and cooling system.

Here are important points to understand about mold detection in heating and cooling systems:

  • Many sections of your heating and cooling system may not be accessible for a visible inspection, so ask the service provider to show you any mold they say exists.
  • Although a substance may look like mold, a positive determination can be made only by an expert and may require laboratory analysis for final confirmation. For about $50, some microbiology laboratories can tell you whether a sample sent to them on a clear strip of sticky household tape is mold or simply a substance that resembles it.
  • If you have insulated air ducts and the insulation gets wet or moldy, it can’t be effectively cleaned. Remove and replace it.
  • If the conditions causing the mold are not corrected, it will recur.
  • Ducts are infested with vermin, e.g. (rodents or insects)
  • Ducts are clogged with excessive amounts of dust and debris and/or particles are actually released into the home from your supply registers.
