After we complete the cleaning process, we have a sanitizer that may be applied to the entire duct system. This is an FDA and EPA registered product, that has been tested and proven effective against a broad spectrum of microorganisms, eliminates odors, without any lingering toxic chemical residue or odor in the duct system. We received an extensive background in the heating and air-conditioning field prior to starting our air duct cleaning business. This knowledge and understanding of how the heating and cooling system works, enables us to provide meticulous attention to every aspect of your unit. Our team is also experts in diagnosing potential hazards or problems for your home or business.
