What to do if you have mold in your air vents?

Search yellowpages.com for duct cleaning...price will vary depending on size of your home and amount of mold. Mold is VERY hazardous to your health(along with family and pets). Can you really put a price on your health? Besides the longer you leave it go the worst you will begin to feel. If you ever try to sell your house this will also pose a problem. Get several quotes then pick the best company(even if not the cheapest) and tell them you would really like to do business with them but so and so bid a lower price and ask if they can match it. The economy is bad enough that most companies will take a little price reduction over no job at all.
