Is it really necessary to have my air ducts cleaned

Air duct cleaning is a misunderstood component of the building. Some of the questions we often hear are: 1. is it really necessary to have my air ducts cleaned? 2. How often should I be cleaning the duct system? 3. How should I choose a qualified air conveyance system technician? Let’s take these questions one at a time and go over them. Clink on one or more of the following questions:

1. is it really necessary to have my air ducts cleaned?

A. Air pollution, on many occasions, is not seen, i.e. small particles of dust, body skin, bio fragments, and outside particles are part of the dust that collects within the living space of the home or building. These particles are stirred up due to inside activities as well when the heating and or cooling systems are turned on. These particles are carried into the air conveyance system. As particulate moves through the duct system, also called open or closed ducting, the air may be slowed down due to restriction. As the air is slowed down the particles begin to drop out of the air and settle inside the duct work. The heavier the particle, the more air speed required to keep it suspended until it can be filtered out by the filter. The filtration benefits are dependent upon the filter of choice (another subject). What the filtration system is unable to collect at the filter reenters the occupied space. This, on many occasions becomes the dust seen on furniture and other building components.

2. How often should I address the cleaning of the air duct system?
3. How should I choose a qualified air conveyance system “cleaning” technician?
