How to select an air duct cleaning company?
There are health advantages for all residents from regularly washing the Heating, Ventilation, Air Conditioning (HVAC) System.
Heating, ventilation, and air conditioning (HVAC) systems collect mold, fungi, bacteria and many different contaminants that reduce the standard of the air residents and visitors breathe. A dirty air duct plays a part in poor indoor air quality and affects the health of people in the residence.
The purpose of residential air duct cleaning would be to remove these contaminants coming from a home’s HVAC system to get the best indoor quality of air.
The best way to clean up an air duct or ventilation system is to apply a specialized, powerful vacuum which puts the air duct / ventilation system under negative pressure. As the vacuum draws air through the system, products are inserted into the ducts to dislodge contaminants and debris from your interior surfaces, moving the contaminants/debris from your home’s air ducts and ventilation systems into the vacuum.
Vacuum collection alone fails to 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).
Anti-microbial chemical sanitizers are placed on the inside surface of the air ducts to manage microbial contamination…but…before sanitizers are utilized, the device should be thoroughly cleaned. All anti-microbial chemicals used should 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 for use on porous system surfaces – including fiberglass surfaces.
When sanitizing air ducts you need to make sure the air duct cleaning company uses safe; effective EPA approved products that are safe for folks, pets, and the environment. An atomizer fogs the sanitizing product throughout the entire ventilation system.
Allergic people, infants and elderly are particularly understanding of the microbes that can cause respiratory problems like bacteria, mildew, fungi algae and dust mites which need a highly-effective sanitizer to get rid of odor-causing microorganisms as well contaminants associated with allergies, mildew and bacterial growth. Ensure that the sanitizer is rated by 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 there are no harmful dermal (skin), ocular (eyes), inhalation (breathing) or ingestion (swallowing) effects through the products.
The two main popular types of vacuum collection systems…those mounted on trucks and trailers versus portable units. Truck/trailer mounted devices are generally stronger than portable equipment. By contrast, portable equipment often may be brought straight into a facility, choosing the vacuum even closer to the ductwork. Both types of equipment clean to air duct industry standards. Vacuum units needs to be mounted on a collection device for safe containment just before disposal. A vacuum collection device which exhausts indoors should be HEPA (high efficiency particulate arrestance) filtered.
The frequency of air duct (HVAC) cleaning is dependent upon several factors:
