Derek Cole explains why air handlers in dark, damp spaces like crawl spaces breed mold and mildew, causing odors. He argues for using nature-derived products, technology that has existed for billions of years, to control microbial growth inside HVAC units.

We have technology available. It's not technology, it's Mother Nature technology. I mean, it's stuff that's been around for billions of years. Natural products that can help smells, odors, growth. We have all this stuff that we can deploy inside your home. The reason it's there is because your air handler, the inside of your unit, is in a space, a crawl space or attic or vertical in the garage where there is no natural sunlight. The reason it's growing these things and making these smells is because it's in a damp, dark environment and what happens? Things start to grow. I've said it before, but you go to the north side of a tree or look at the north side of a house, moss and algae, mildew. All that green stuff you see when you pass by somebody's house, okay, well, that's the north side because there is no sunlight. Where there is sunlight, that does not exist. So same technology inside your unit.
