Dr. Jill Crista covers the best technique for cleaning HVAC ducts after mold remediation.
Today we are talking about duct cleaning. Yes, you absolutely need to have your ducts cleaned after you have had mold in your home and had it remediated; because where there is dust, there will be mold. And I want you to use a mold remediation company to do your duct cleaning. Here’s why. They will seal every place that air can come into your house. Cold air returns and every vent in your house needs to be sealed before this job is done. Otherwise, they go in there and poof, spores go all over your house again. Second, they will have an air scrubber that will be sucking all of the bad air out of those ducts as they’re cleaning it and disrupting the material and that will all be sent outside so it won’t make your indoor environment sick. Third, you’ll want to make sure your remediation company’s using wire scrub brushes which are about this big and it’s very noisy but as they go through the ducts, it will actually pull and disrupt that mold. Because there’s no way to just get a good high-powered vacuum in there and get all that up. It needs to be disrupted which is why you need to seal all the ducts, seal the air return and then get an air scrubber so that you’re safe. That’s how you do a good duct cleaning after you’ve done a remediation in your house.
