Trusted & Accurate Information Regarding Duct Cleaning

The DC Rating Score explained

The DC Rating Score is our effort to evaluate a duct cleaning businesses background based on the public information available online. We create the rating using a model that considers information from several sources (NADCA, BBB, Google, Yelp, Home Advisor, HomeStars …). Any information that affects the DC Rating score is visible on a businesses profile page.

A Duct Cleaning Business always has the opportunity to add information to their business page, and those businesses who support with more information tend to have a higher rating than those who do not.

Keep in mind that these ratings speak to a duct cleaners background, but do not evaluate their past performance, customer service, or communication skills. These are elements that the DC Rating Score cannot evaluate.
