Do you or someone in your family have allergies? Hay fever maybe. Although the EPA does not recommend routine duct cleaning, it does suggest that it be done when there are specific reasons for doing so, such as:
- You see substantial amounts of visible mold growth within the heating ducts or present on other parts of your home’s HVAC system.
- Pests such as mice, rats or insects have infested portions of the duct system.
- Excessive amounts of dust or debris clog the duct system and release dust or debris into the home through the vent registers when the system operates.
