My house will be 25 years old this August and the air ducts have never been cleaned. I have two cats in the house and the normal amount of dust. I am thinking of having this done but I am sure it is a bit pricey, so I guess I am asking is it necessary? And is it worth it? What I would really like is for someone to check the air ducts and see if there are any repairs needed, no animals getting into them etc. Can this be done without going to all the expense of cleaning? I read mixed reviews on the necessity of cleaning them, but don't know what to think.
As some of you know I lost my husband suddenly almost 4 years ago and I have no other family, so don't really have someone to ask about these kind of things except the people who performs the service and of course they want to sell. Any opinions will be appreciated. Thanks.
