How Does Dyna-Vac Clean the Ductwork?

Dyna-Vac uses the SOURCE REMOVAL method of cleaning, a method endorsed by the National Air Duct Cleaners Association (NADCA).  SOURCE REMOVAL duct cleaning includes effective "scrubbing" of the inside surfaces of the ducts to loosen the dust.  "Scrubbing" can be accomplished with either a duct ball or duct brush.  Dyna-Vac uses a one-inch diameter duct ball, connected by a hose to an air compressor.  High pressure air (200 PSI) is forced into the ductwork, dislodging the tightly lodged mites, spores, molds, and bacteria along with the dirt and dust adhering to the interior surfaces of the duct.  Either method of "scrubbing" breaks loose the build-up of dust and allows the vacuum with its powerful suction to pull the debris out of the system.

Dyna-Vac believes it is necessary to clean the entire heating and cooling system to achieve the highest "contamination free" results as possible and offers a complete cleaning, servicing, and inspection of the furnace and cleaning of the air conditioning coil in addition to ductwork cleaning.  We are convinced our experienced personnel and truck-mounted power vac unit provide on of the most complete duct cleaning services available.  Many other cleaners use relatively low-powered vacuuming methods that will not adequately draw out dust and other contaminats clinging to the interiors of ductwork.

Dyna-Vac, unlike many other companies, sells no products (i.e., filters, furnaces).  However, we can make many recommendations concerning filters and heating and cooling equipment.  Our recommendations are based solely on the performance of products as observed in the field.

Why Should Air Ducts Be Cleaned?

Cleaning air ducts is important today because the medical field, including industrial hygienists are finding that people are adversely affected by dirty air.  It causes people to sneeze, allergies get "turned on", and some folks complain about feeling lousy.  The same dirty air that is going through uncleaned ventilating systems is going through people's breathing systems.  Hence, indoor air pollution.

Dust is in the environment and ventilation ducts contain lots of dust.  The fans in the air handling units (furnace) channel dust laden air through the ducts.  Ducts and dust go together.  That is why furnace manufacturers design filters for air handling units.  However, filters don't catch all the dust.  Over time, dust accumulates inside the air ducts.  When the HVAC system runs, it becomes a distributor of dust throughout a house.

The air that we breathe continuously contains two potentially harmful irritants:  particulates and bilogical contaminatns (living or dead organisms).

Particulates include dust, human and pet hair, lint from clothing, carpet fibers, and particulates of tobacco smoke.  Biological contaminants include bacteria spores (seeds), polled, human and pet dander, viruses, molds, and fungi spores.
