The best way to select an air duct cleaning company?
There are health benefits for all residents from regularly cleaning the Heating, Ventilation, Air Conditioning (HVAC) System.
Heating, ventilation, and air conditioner (HVAC) systems collect mold, fungi, bacteria and a number of contaminants that reduce the caliber of air residents and visitors breathe. A dirty air duct plays a part in poor indoor air quality and affects the health of folks the residence.
The objective of residential air duct cleaning is always to remove these contaminants from a home’s HVAC system for the best indoor quality of air.
The most effective way to clean an air duct and ventilation system is to apply a specialized, powerful vacuum which puts air duct / ventilation system under negative pressure. As the vacuum draws air with the system, products are inserted into the ducts to dislodge contaminants and debris through the interior surfaces, moving the contaminants/debris through the home’s air ducts and ventilation systems to the vacuum.
Vacuum collection alone fails to clean the HVAC system. Brushes, air whips, “skipper balls” along with 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 applied to the interior top of the air ducts to manage microbial contamination…but…before sanitizers are utilized, the device should be thoroughly cleaned. All anti-microbial chemicals used has to be EPA registered to use in HVAC systems. Ask to see the chemical’s Material Safety Data Sheet (MSDS). If you are still concerned, call the EPA at 1-800-438-4318. You will find no EPA registered anti-microbial products for use on porous system surfaces – like fiberglass surfaces.
When sanitizing air ducts you want to ensure the air duct cleaning company uses safe; effective EPA approved products which are secure for individuals, pets, and also the environment. An atomizer fogs the sanitizing product through the entire entire ventilation system.
Allergic people, infants and elderly are especially sensitive to the microbes that induce respiratory problems like bacteria, mildew, fungi algae and dirt mites which demand a highly-effective sanitizer to remove odor-causing microorganisms too contaminants connected with allergies, mildew and bacterial growth. Ensure the sanitizer is rated from the EPA as being a category IV product with all the lowest toxicity rating. Sanitizing air ducts means toxicity and safety safeguards that establish and ensure you will find no harmful dermal (skin), ocular (eyes), inhalation (breathing) or ingestion (swallowing) effects from the products.
There are 2 popular kinds of vacuum collection systems…those mounted on trucks and trailers versus portable units. Truck/trailer mounted equipment is generally stronger than portable equipment. By contrast, portable equipment often can be brought right into a facility, choosing the vacuum even closer to the ductwork. Both varieties of equipment clean to air duct industry standards. Vacuum units should be connected to a collection device for safe containment just before disposal. A vacuum collection device which exhausts indoors has to be HEPA (high efficiency particulate arrestance) filtered.
The frequency of air duct (HVAC) cleaning depends upon several factors:
*before occupying a whole new home.
*afterhome renovations or remodeling.
*quantity of smokers in the household.

*Water contamination or injury to the house or HVAC system.
*Residents with allergies or asthma reap the benefits of better indoor air quality.
The United States Environmental Protection Agency states that “duct cleaning services” typically range in price from $450 to $1000 per heating and cooling system, depending on the services offered, the size of the program to become cleaned, system accessibility, climatic region, degree of contamination” and type of duct material.
