HomeSeal

Negative air cleaning might sound like something from a science-fiction story, but in fact, it's one of the techniques that HomeSeal technicians use to clean ducts inside their clients' homes. They also use Rotobrushing and air pressurization to clear away dust, mold, and other contaminants, videotaping all the while so that customers can see the state of ducts before and after each service. Clients can also opt for specialists to install spray-foam insulation in basements, attics, and other areas, lowering energy bills throughout the year.
