Each year millions of homes across the U.S. hire professionals like ourselves to clean out their air ducts. San Diego County is perhaps one of our biggest markets but it’s also where people may choose to undertake the job of cleaning their own home’s air ducts. As a matter of fact, doing it yourself is a great way to save money if you have the time. So, the most common question that we’re asked is what type of sealant works best and why? Some home owners even try to find out if they can use sealant on their own and save money by not hiring us – which is perfectly fine. This is why we’ve decided to put together some information that most people will find useful.
