How you can select an air duct cleaning company?

The purpose of residential air duct cleaning is always to remove these contaminants from the home’s HVAC system for the best indoor quality of air.
The best way to clean up an air duct or ventilation system is by using a specialized, powerful vacuum which puts the environment duct / ventilation system under negative pressure. While the vacuum draws air through the system, devices are inserted to the ducts to dislodge contaminants and debris through the interior surfaces, moving the contaminants/debris from the home’s air ducts and ventilation systems to the vacuum.
Vacuum collection alone does not clean the HVAC system. Brushes, air whips, “skipper balls” as well as other tools that agitate contaminants and debris scrub the surfaces within the air duct system and propels contaminants and debris into the vacuum collection device(s).

All anti-microbial chemicals used must be EPA registered to use in HVAC systems. Ask to find out the chemical’s Material Safety Data Sheet (MSDS).

Sanitizing air ducts means toxicity and safety safeguards that establish and make sure you will find no harmful dermal (skin), ocular (eyes), inhalation (breathing) or ingestion (swallowing) effects from your products.
There are 2 popular kinds of vacuum collection systems…those installed on trucks and trailers versus portable units. Truck/trailer mounted devices are generally more robust than portable equipment. By contrast, portable equipment often may be brought straight into a facility, locating the vacuum even closer to the ductwork. Both types of equipment clean to air duct industry standards. Vacuum units ought to be mounted on a collection device for safe containment just before disposal. A vacuum collection device which exhausts indoors must be HEPA (high efficiency particulate arrestance) filtered.
