We cannot live without air—it’s the most important thing for every single one of us. So of course it’s the most important thing for your customers. And one of the best ways you can serve them is by ensuring the air they’re breathing is the best it could possibly be.

This week, Drew Cameron is continuing his conversation on air and indoor air quality. He’ll walk through some eye-opening metrics on what exactly it is we’re breathing, and some proven points you need to know whenever you enter your customers’ homes to have a conversation.

All that and more on this week’s Cracking the Code! Watch, free for everyone, through January 30th: MyContractorUniversity.com/CBS-Show.
