I bought a 6 year old home and found that they NEVER had filters in the return air ducts. We immediately went out and purchased some and have installed them. Do I need to hire someone to clean the ductwork (the previous, filthy owners had 5 pets in the house and never cleaned!)?
Could this have damaged the air conditioning unit or furnace?
If we need to have the ductwork cleaned how do we go about hiring someone who knows what they are doing?
Your local heating/AC contractors - the ones that would normally service your heating/AC system - will either
clean the duct work or recommend someone to do it. They will probably charge by the room and it won't be
cheap. I'm guessing that seven or eight rooms will cost around $1,000.
