Duct cleaning refers to the clean out of the supply, intake, and return ducts throughout your home. It should be completed by a professional duct cleaning company with the proper training and is equipped with the appropriate tools for the job: specialized blowers, vacuums, brushes, etc.
Levels of air pollution can be 2-5 times higher than outdoor pollution. Household ducts usually contain dust, mites, mold, pollen, and animal dander that get cycled through your home on average of 3-5 times daily. It is normal to find some level of dust in household ducts. As long as all components of the HVAC unit were properly installed and stay well maintained, the dust levels should not grow to be excessive and other contaminates should be at a minimal.

Mold Growth: If moisture is present, the potential for mold growth increases. Spores can be released into living areas and contaminate the air. Airborne mold exposure can potentially cause allergic reactions and/or other symptoms.

Often times it is difficult to visually spot mold in your HVAC system. Sometimes mold is accompanied by a musty odor. An inspector will be equipped with the proper tools (i.e: moisture meters, thermal image, etc.) to find and identify mold threats.

It is also important to control moisture build up with the system. Taking the time to implement proper HVAC maintenance checks will help to prevent mold growth.
Vermin: If your ducts are in infested with vermin (i.e: rodents or insects), you should consider having your ducts cleaned once the infestation has been eliminated. Rodents and insects tend to leave behind hazardous bacteria. Whether it is from hair and dander or fecal matter, it is something that should be cleaned out.
Excessive Dust and Debris: If all components of the HVAC system are not well maintained, dust and debris can build up beyond normal levels. Excessive dust and debris should be cleaned out from your ducts. While normal levels of dust in the ducts can be harmless, elevated dust and debris levels clogging the ducts can release into the home from the supply registers.
- Factors that contribute to elevated dust and debris levels: Pets, smoking, recent renovations, local weather conditions, and overall home cleanliness.
- While clogged air ducts can potentially diminish the air quality in your home, they can also reduce the efficiency of your HVAC system. When the various components of your air system is loaded with dust and debris, the system has to work harder to accomplish the same work. When you clean out the debris, it will contribute to energy consumption savings.
