How you can select an air duct cleaners?
You will find health advantages for all residents from regularly washing the Heating, Ventilation, Air Cooling (HVAC) System.
Heating, ventilation, and air cooling (HVAC) systems collect mold, fungi, bacteria and a number of contaminants that reduce the standard of the environment residents and visitors breathe. A dirty air duct plays a role in poor indoor air quality and affects the fitness of people in the residence.
The goal of residential air duct cleaning is to remove these contaminants coming from a home’s HVAC system for the greatest indoor air quality.
The best way to clean up an air duct or ventilation system is by using a specialized, powerful vacuum which puts the air duct / ventilation system under negative pressure. As the vacuum draws air with the system, devices are inserted into 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 will not clean the HVAC system. Brushes, air whips, “skipper balls” along with other tools that agitate contaminants and debris scrub the surfaces inside the air duct system and propels contaminants and debris to the vacuum collection device(s).
Anti-microbial chemical sanitizers are placed on the inner top of the air ducts to regulate microbial contamination…but…before sanitizers are employed, the system ought to be thoroughly cleaned. 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). If you are still concerned, call the EPA at 1-800-438-4318. You can find no EPA registered anti-microbial products to be used on porous system surfaces – such as fiberglass surfaces.

Ensure the sanitizer is rated through the EPA being a category IV product using the lowest toxicity rating. 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 the products.
There are 2 popular types of vacuum collection systems…those installed on trucks and trailers versus portable units. Truck/trailer mounted devices are generally stronger than portable equipment. By contrast, portable equipment often could be brought straight into a facility, locating the vacuum nearer to the ductwork. Both kinds of equipment clean to air duct industry standards. Vacuum units ought to be attached to a collection device for safe containment just before disposal. A vacuum collection device which exhausts indoors should be HEPA (high efficiency particulate arrestance) filtered.
