We open, agitate, and vacuum the entire duct work under negative pressure. We remove, wipe down, and re-install the register openings. We clean the plenum, blower blades, and cooling coils. All the products we use are EPA regulated and safe for your home and for use in your air system. After the ducts are clean, we apply an anti-microbial which deodorizes and disinfects the ducts, leaving them clean and sanitized.
