Answer:  Because they get dirty!

In addition to the normal accumulations of dust and dirt found in all homes through regular use, there are several factors that can increase the need for air duct [auth] cleaning:

•  Pets

•  Occupants with allergies or asthma

•  Cigarette or cigar smoke

•  Water contamination or damage to the home/

HVAC system

Some occupants are more sensitive to these contaminants than others.

Allergy and asthma suffers, as well as young children and the elderly tend to be more susceptible to the types of poor indoor air quality that air duct cleaning can help to address.

Inspect your air ducts

You can tell if your heating, ventilation and air conditioning (HVAC) system needs cleaning by one of two ways.

First, with a screwdriver, remove a floor or wall register.


1)  Use a small mirror and flashlight  -or-

2)  Use a digital camera to take a picture inside the duct.

If there is visible dust, dirt or debris, you should have your ducts cleaned.

What you need to know about air duct cleaning

Air duct cleaning is a misnomer. In actuality, the entire HVAC system should be cleaned. Failure to clean all components of the system can result in recontamination of the entire system, thus minimizing the benefits of cleaning. Just as you wouldn’t only clean half of your living room floor, you also would not want to clean only part of your heating, ventilation and air conditioning (HVAC) system.

The National Air Duct Cleaners Association (NADCA) recommends cleaning the entire HVAC system, including the following components:

∆  Air ducts

∆  Air plenum

∆  Coils

∆  Blower motor and assembly

∆  Drain pan

∆  Heat exchanger

∆  Registers

∆  Air filter

∆  Grills

∆  Air cleaner

There are two key components to proper HVAC cleaning: breaking contaminants loose, and collection of contaminants.

Breaking contaminants loose

Properly cleaning HVAC systems requires removing the sources of contamination. Source removal begins with the use of one or more agitation devices designed to loosen contaminants from the surfaces within the heating and air conditioning system.

Examples of agitation devices include brushes, air whips and compressed air nozzles or “skipper balls.” Agitation can also be achieved through hand-brushing or contact vacuuming.

Collection of contaminants

During cleaning, the entire HVAC system is placed under continuous negative pressure (vacuum) to prevent the spread of contaminants. Continuous negative pressure allows very fine particles to be removed from the system as they become airborne, ensuring that these particles are not released into the living space when the system is turned on after cleaning. This negative pressure also serves to extract the loosened contaminants, which are collected and removed from your home.
