Air Duct Cleaning = Improved Indoor Air Quality

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.

How our Air Duct Cleaning is Performed

We utilize a truck mounted vacuum that attaches to your ductwork in the vicinity of your furnace via a 10″ diameter hose. Once we turn the vacuum on, it will draw air in reverse through the air duct system. Having setup the duct vacuum, our technician will then bring a second hose into your home (this hose is attached to an air compressor) and use a fitting at the end of it to blow high pressure air down each individual supply air and return air duct throughout the home. The various fittings attached to the end of this air compressor hose are physically inserted into the duct, and the high velocity air exiting the hose is blown against the sidewalls of the ductwork loosening dust and debris, 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 insert an aggravating brush into the ductwork to dislodge the dust and debris. 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 for your typical residence.
