How you can select an air duct cleaning company?
You can find health and fitness benefits 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 standard of the air residents and visitors breathe. A dirty air duct plays a role in poor indoor quality of air and affects the healthiness of individuals the residence.
The objective of residential air duct cleaning is to remove these contaminants coming from a home’s HVAC system to get the best indoor air quality.
The simplest way to clean up an air duct and/or ventilation system is by using a specialized, powerful vacuum which puts air duct / ventilation system under negative pressure. As the vacuum draws air with the system, items are inserted into the ducts to dislodge contaminants and debris from the interior surfaces, moving the contaminants/debris through 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” and other tools that agitate contaminants and debris scrub the surfaces within the air duct system and propels contaminants and debris in to the vacuum collection device(s).
Anti-microbial chemical sanitizers are applied to the inner surface of the air ducts to manage microbial contamination…but…before sanitizers are employed, the system should be thoroughly cleaned. All anti-microbial chemicals used should 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.

Allergic people, infants and elderly are especially sensitive to the microbes that induce respiratory problems like bacteria, mildew, fungi algae and dust mites which require a highly-effective sanitizer to eliminate odor-causing microorganisms also contaminants related to allergies, mildew and bacterial growth. Make sure the sanitizer is rated by the EPA being a category IV product with 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.
There are 2 popular types 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 could be brought right into a facility, locating the vacuum nearer to the ductwork. Both types of equipment clean to air duct industry standards. Vacuum units should be attached to a collection device for safe containment before disposal. A vacuum collection device which exhausts indoors has to be HEPA (high efficiency particulate arrestance) filtered.

Accumulated dirt and debris is effective in reducing the CFM (cubic feet of air a minute) around 50%! This is the most frequent reason for cracks in heat exchangers. Having your HVAC system cleaned may prevent pre-mature breakdown & aging of your own cooling and heating system.
Reduce Dusting Air duct cleaning minimises household dust by removing the dust where it travels most – using 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 might help to improve efficiency and thus may aid in reducing cooling and heating costs.
