How to select an air duct cleaning company?
There are health advantages for all residents from regularly cleaning the Heating, Ventilation, Air Conditioner (HVAC) System.
Heating, ventilation, and air cooling (HVAC) systems collect mold, fungi, bacteria and a variety of contaminants that reduce the caliber of air residents and visitors breathe. A dirty air duct plays a part in poor indoor quality of air and affects the health of people in the residence.
The purpose of residential air duct cleaning is always to remove these contaminants coming from a home’s HVAC system for the greatest indoor quality of air.
The most effective way to clean an air duct or ventilation system is by using a specialized, powerful vacuum which puts the air duct / ventilation system under negative pressure. Whilst the vacuum draws air through the system, products are inserted to the ducts to dislodge contaminants and debris from your interior surfaces, moving the contaminants/debris from the home’s air ducts and ventilation systems in to the vacuum.
Vacuum collection alone will not clean the HVAC system. Brushes, air whips, “skipper balls” as well as other tools that agitate contaminants and debris scrub the surfaces in the air duct system and propels contaminants and debris to the vacuum collection device(s).
Anti-microbial chemical sanitizers are put on the inner top of the air ducts to regulate microbial contamination…but…before sanitizers are used, the device needs to be thoroughly cleaned. All anti-microbial chemicals used must be EPA registered to be used in HVAC systems. Ask to see the chemical’s Material Safety Data Sheet (MSDS). In case you are still concerned, call the EPA at 1-800-438-4318. There are no EPA registered anti-microbial products to use on porous system surfaces – such as fiberglass surfaces.

Ensure that the sanitizer is rated through the EPA as being a category IV product using the lowest toxicity rating. Sanitizing air ducts means toxicity and safety safeguards that establish and ensure you can find no harmful dermal (skin), ocular (eyes), inhalation (breathing) or ingestion (swallowing) effects from your products.
The two main popular kinds of vacuum collection systems…those attached to trucks and trailers versus portable units. Truck/trailer mounted equipment is generally more robust than portable equipment. By contrast, portable equipment often can be brought straight into a facility, seeking the vacuum nearer to the ductwork. Both kinds of equipment clean to air duct industry standards. Vacuum units ought to be mounted on a collection device for safe containment prior to disposal. A vacuum collection device which exhausts indoors must be HEPA (high efficiency particulate arrestance) filtered.
