Air duct cleaning by Swif duct cleaning helps directly by removing all of these allergens from within the HVAC system, and indirectly by helping maintain the efficiency of your air conditioning and heating units. In the summer, when pollen counts can be so high outside, running the air conditioner instead of opening the windows will reduce humidity in your home, as well as filtering out the allergens that pass through the air ducts to the cooling unit. We offer an excellent electrostatic filter for continuous home air cleaning.
