• There is visible mold growth inside the ductwork or other HVAC components.
• Your ducts are infested with pests, such as rodents or insects.
• Your air ducts are clogged with an excessive amount of dust and debris.
• You or someone in your household experiences increased allergy or asthma symptoms when the HVAC system is running.

• Inspection: The technician will inspect your HVAC system to determine if cleaning is necessary and to assess the extent of the contamination.
• Creating negative pressure: The service provider will use a powerful, specialized vacuum system to place the entire HVAC system under continuous negative pressure. This prevents dust and other particles from spreading into your home during the cleaning.
• Source removal: Brushes, air whips, and compressed air nozzles are used to dislodge stubborn debris from the ductwork.
• Component cleaning: All other accessible HVAC components—including the coils, drain pan, fan, and housing—will be cleaned.
• Re-sealing: Any access holes made during the cleaning process are sealed so they are airtight.
• Optional treatments: The technician may recommend applying antimicrobial treatments to disinfect the ducts or sealants to encapsulate interior surfaces, but you should ask for clarification on the pros and cons of these options. 

As you might expect, many variables can contribute to the air duct cleaning price to include the size of your home, complexity of the ductwork, and the level of contamination to be removed.
