Over the years, a significant amount of particulate—such as pollen, animal dander, dust, and so on— accumulates in the air ducts of a home. Every time your heating and cooling system turns on, air begins moving through the ductwork, stirring up settled particulate. The chances are you will end up breathing some of this particulate while the remainder settles on your furniture and carpet. This can be both a nuisance and a health concern. For example, allergies and asthma can be aggravated by these airborne pollutants, and we all know having to dust around our homes is time consuming and undesirable. Our duct cleaning service is one of the methods Overlake can provide you with better indoor air quality.
We utilize a truck mounted vacuum that uses a 10" diameter hose to attach to your ductwork near your furnace. The vacuum will draw air "in reverse" through the air duct system via this hose. Once the vacuum is up and running, the technician will take a second hose that is attached to an air compressor to each individual supply air duct and return air duct throughout the home. The various fittings attached to the end of this air compressor hose are inserted into the duct, and high velocity air is released against the sidewalls of the ductwork. This high pressure air knocks settled particulate loose from the inner walls of the air duct, which is then drawn out by the vacuum (the effect is similar to using a water based pressure washer to clean some solid surface).
We choose not to use any chemical sprays marketed to kill bacteria, mold, and so on, because these tend to leave residue in your air ducts that evaporates and ends up in the air you breathe. We also do not use an aggravating brush to dislodge the dust and debris from the sidewalls of the ductwork. The brush system can work well if all the air ducts throughout the home are rigid metal, but most residences utilize a fair amount of flexible ductwork which is more fragile (it can be torn or knocked down fairly easily). We believe the high pressure air system we utilize is the most effective and safe air duct cleaning system available today.
