Indoor Air Quality (IAQ) issues are rapidly becoming part of the general public’s consciousness through the mass media's portrayal of proliferating toxic mold. Many consumers are now discovering that non-qualified commercial mold remediation firms and residential duct cleaning services can be just as hazardous.

Unfortunately, these schemes make business difficult for the good-faith companies. So it’s important to know that not all air duct cleaning is a scam and that not all air duct cleaners are equal. Duct cleaning can have marked therapeutic benefits if performed professionally.

Most people are now aware that indoor air pollution is an issue of growing concern and increased visibility. Many companies are marketing products and services intended to improve the quality of your indoor air.

You have probably seen an advertisement, received a coupon in the mail, or been approached directly by a company offering to clean your air ducts as a means of improving your home's indoor air quality. Dateline NBC’s Chris Hansen’s and the The Hansen Files made many in America aware of the $79 “bait and switch” scams that have been going on for decades. To professionally clean an average HVAC system it may typically — but not always — range in cost from $500 to $1,000 per heating and cooling system, depending on the services offered, the size of the system to be cleaned, system accessibility, climatic region, and level of contamination.
