Fonder Air Duct Cleaning completely removes all contaminants found inside duct work. These contaminants are not just dirt and dust but dead rodents,insects,animal hair,drywall dust, etc. When we come in to clean your home/office there is an electrically driven, rotating brush we insert into your air ducts, that removes all that is adhered to the inside of ducts. When this process is complete the air compressor hose is inserted and this blows all of the contaminants into our powerful vacuum system Not only does this clean your home/office and inside air, the removal of contaminants also benefits your health. You will not breathe in all of that unclean air. This is good for everyone especially those with health problems already such as asthmatics or those with respiratory problems.
