The best way to select an air duct cleaners?
You will find health benefits for all residents from regularly cleaning the Heating, Ventilation, Air Conditioner (HVAC) System.
Heating, ventilation, and air conditioner (HVAC) systems collect mold, fungi, bacteria and a number of contaminants that reduce the quality of the air residents and visitors breathe. A dirty air duct plays a part in poor indoor air quality and affects the fitness of individuals the residence.
The goal of residential air duct cleaning would be to remove these contaminants from a home’s HVAC system to get the best 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 environment 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 the interior surfaces, moving the contaminants/debris from your home’s air ducts and ventilation systems in to the vacuum.
Vacuum collection alone does not clean the HVAC system. Brushes, air whips, “skipper balls” and other tools that agitate contaminants and debris scrub the surfaces in the air duct system and propels contaminants and debris into the vacuum collection device(s).
Anti-microbial chemical sanitizers are applied to the inner surface 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 should be EPA registered for use in HVAC systems. Ask to view 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 to use on porous system surfaces – such as fiberglass surfaces.
When sanitizing air ducts you would like to ensure that the air duct cleaning company uses safe; effective EPA approved items that are secure for individuals, pets, and the environment. An atomizer fogs the sanitizing product throughout the entire ventilation system.
Allergic people, infants and elderly are specifically responsive to the microbes that can cause respiratory problems like bacteria, mildew, fungi algae and dirt mites which require a highly-effective sanitizer to remove odor-causing microorganisms also contaminants related to allergies, mildew and bacterial growth. Ensure that the sanitizer is rated by 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 will find no harmful dermal (skin), ocular (eyes), inhalation (breathing) or ingestion (swallowing) effects from your products.
There are 2 popular varieties of vacuum collection systems…those attached to trucks and trailers versus portable units. Truck/trailer mounted devices are generally stronger than portable equipment. By contrast, portable equipment often can be brought directly into a facility, locating the vacuum nearer to the ductwork. Both kinds of equipment clean to air duct industry standards. Vacuum units should be mounted on a collection device for safe containment before disposal. A vacuum collection device which exhausts indoors should be HEPA (high efficiency particulate arrestance) filtered.
The regularity of air duct (HVAC) cleaning is dependent upon several factors:
*before occupying a new home.
*afterhome renovations or remodeling.
*quantity of smokers in the household.

Health According to the EPA, indoor air is located to become as much as 70 times more polluted than outdoor air. Air duct cleaning removes airborne contaminates including bacteria, fungus, mold spores, pet dander & pollen which can help to alleviate allergy & asthma symptoms.
Extended Equipment Life 9 away from 10 system failures are caused by dirt and dirt according to the Louisiana Cooperative Extension Service. One of the functions of the fan, located inside your air handler, is always to maintain the nvtiuk exchanger cool. Accumulated dirt and debris is effective in reducing the CFM (cubic feet of air each minute) around 50%! This is actually the most frequent cause of cracks in heat exchangers. Having your HVAC system cleaned may prevent pre-mature breakdown & aging of your own heating and air conditioning system.
Reduce Dusting Air duct cleaning reduces household dust by taking out the dust where it travels most – through your air duct system.
Energy Savings Based on the EPA, a buildup of only.042 inches of dirt over a heating coil might occur in a reduction in efficiency of 21%. A clean air conveyance system can help to increase efficiency and for that reason may aid in reducing heating and cooling costs.
