How you can select an air duct cleaners?
You will find health benefits for all residents from regularly cleaning the Heating, Ventilation, Air Conditioning (HVAC) System.

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 most effective way to wash an air duct and ventilation system is by using a specialized, powerful vacuum which puts air duct / ventilation system under negative pressure. As the vacuum draws air from the system, devices are inserted in to the ducts to dislodge contaminants and debris through the interior surfaces, moving the contaminants/debris from the home’s air ducts and ventilation systems 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 inside the air duct system and propels contaminants and debris to the vacuum collection device(s).
Anti-microbial chemical sanitizers are placed on the inside top of the air ducts to manage microbial contamination…but…before sanitizers are employed, the program should be thoroughly cleaned. All anti-microbial chemicals used has to be EPA registered for use in HVAC systems. Ask to find out the chemical’s Material Safety Data Sheet (MSDS). Should you be 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.

Make sure the sanitizer is rated by the EPA being a category IV product with all the lowest toxicity rating. Sanitizing air ducts means toxicity and safety safeguards that establish and ensure there are no harmful dermal (skin), ocular (eyes), inhalation (breathing) or ingestion (swallowing) effects from your products.
There are two popular kinds of vacuum collection systems…those installed on trucks and trailers versus portable units. Truck/trailer mounted devices are generally more powerful than portable equipment. By contrast, portable equipment often could be brought directly into a facility, choosing the vacuum nearer to the ductwork. Both types of equipment clean to air duct industry standards. Vacuum units needs to be attached to a collection device for safe containment just before disposal. A vacuum collection device which exhausts indoors must be HEPA (high efficiency particulate arrestance) filtered.

One of many functions from the fan, located inside your air handler, is to keep your 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 common reason for cracks in heat exchangers. Having your HVAC system cleaned may prevent pre-mature breakdown & aging of your cooling and heating system.
Reduce Dusting Air duct cleaning helps to reduce 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 just.042 inches of dirt on the heating coil can result in a reduction in efficiency of 21%. A clean air conveyance system may help to boost efficiency and for that reason may help to reduce heating and cooling costs.
