Welcome to

Our HVAC Duct Cleaning and Dryer Vent Cleaning Services in Atlanta, GA, help clean the Air your Family & Employees Breathe.

Get the peace of mind that comes from breathing clean air. Duct cleaning is one of the healthiest home improvement investments a homeowner can make. We use a Rotobrush machine, designed exclusively for duct cleaning. This machine is a large HEPA filter vacuum that has a hose with a motorized brush at the end. This brush spins throughout your ductwork, agitating any mold, bacteria, fungi, or other harmful organic materials. After the cleaning process is complete, we then sanitize the system with an antimicrobial compound that eliminates bacteria, mold, mildew, fungi and algae. 

At Quality Air Ducts we take pride in our work. We use the most up to date methods in tandem with cutting edge products to provide you the ability to breathe easily in your home. At QAD we are a family owned and operated business. Our common goal is to be the leader in our industry though our tradition of honesty and fairness to our customers, employees and business partners.

Keep Your Air Clean With Our Quality Air Duct Cleaning Services.

When providing residential air duct system cleaning Quality Air Ducts technicians typically performs the following sequence:


All supply and return registers are carefully removed from the walls of the home. Knife cuts are made around the registers to minimize any separation of paint from the register and the wall.


The blower and blower motor are removed from the furnace. These are some of the dirtiest parts of the system and can only be properly and fully cleaned outside of the house.



A large vacuum type of system is connected to the duct system. This is to place the entire duct system under “negative pressure” to ensure that dirt and debris that is removed during the cleaning process does not migrate into the house. It also provides a means to filter out the dirt and debris generated by the cleaning process.


A rotating brush is inserted into each individual air duct to “break loose” the dirt that is clinging to the duct wall while the negative air machine is pulling air through the duct and filtering out the dirt and debris. This method of cleaning the duct wall is called “mechanical agitation” and is a critical procedure of proper duct cleaning. In some rare cases a device called a whip may be used to spray high pressure air against the duct wall in lieu of the rotating brush.

5. The return air section of the system is cleaned. In some homes this is a dedicated duct running from the return register to the furnace. In other homes this may be a wall cavity that provides a path for air to be returned through the register to the furnace.

6. The inside of the furnace is cleaned. This is the relevant portion of the furnace to clean since this is where the air actually travels. While the technician is cleaning the interior of the furnace it is inspected for any potential problems or defects. After cleaning is complete, QAD technicians will sanitize (biocide fog sanitation) the entire duct system to kill any allergens, mold, and odors to ensure a healthy supply of air that your family breathes.

7. The blower motor and blower that were previously removed from the furnace is cleaned outside of the house and then reinstalled into the furnace.

8. The registers that were previously removed from the wall are cleaned and registers are then installed.

9. The furnace or system is started up. The furnace is placed through a heating cycle and monitored for proper operation. The furnace burners are examined for proper operation and adjusted if possible to operate at maximum efficiency.

10. All ductwork and registered are checked for air flow.

11. All furnishings are returned to their original location.

12. Cleanup, take pictures and depart.

Improve Indoor Air Quality

A study by researchers at Johns Hopkins University found an association between increasing levels of indoor particulate matter pollution and the severity of asthma symptoms among children (click link above for details of the study). A Washington Post article titled “Indoor Air Quality is a Top Health Risk” states “The Environmental Protection Agency has declared the air two to five times as polluted indoors than out, and placed it among the top five environmental risks to public health.” The article continues by citing a spokeswoman for the American Asthma and Allergy Foundation of America, who stated, “The best thing you can do to improve indoor air quality is to put some elbow grease into it,” the spokeswoman continues, “Remove the sources of the allergens….”

Before & After

“Remove the sources of the allergens” is what HVAC Systems Cleaning or Duct Cleaning does – it removes the numerous sources of allergens or contaminants that exist in HVAC Systems. Contaminants like molds, bacteria, fiberglass insulation fibers, dust and debris are all present in your ductwork and given that the ductwork is the lungs of your buildings these containments can all easily be dispersed into the ambient air for the building occupants to inhale. The complexity of large commercial HVAC Systems increases the potential areas where contaminants can accumulate. Large air handler units, terminal boxes installed throughout the system that can be collection points for dirt and debris, ductwork layouts that have 90 degree turns with turning vanes and the existence of fire and smoke dampers where dirt and debris can also accumulate. The increased likelihood of the entrance of moisture to the HVAC System through outside air intakes, sitting water in drain pans, and many other devices in the system also produce potential indoor air quality problems. The combination of moisture and dirt in ductwork can lead to microbial growth, the potential microbial growth can be amplified with the existence of ductwork is internally insulated with fiberglass insulation – which is common in commercial ductwork installations.

Energy Efficiency

In 2005 the American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc. (ASHRAE) a study to determine the effectiveness of coil cleaning vis-à-vis energy savings. The purpose in large part was that logically and theoretically it was known that coil cleaning provided energy savings by increasing air flow and reducing stress on the HVAC System and in turn reduces stress (energy) on the system to operate. Additionally dirty ductwork can load filters quickly and lead to more stress on the air handler and potentially higher energy costs, blockages in reheat coils, mixing boxes.

Dryer Duct Cleaning

According to the Consumer Products Safety Commission 15,600 fires in 1998 were attributed to clothes dryers. Many of these were due to clogged or restricted dryer duct vents. Some common causes of dryer duct clogging are poor design and or installation workmanship of the dryer duct that goes from the dryer to the outside of the house. Some dryer manufacturers recommend dryer duct cleaning once a year. Dirty dryer ducts can cause:

• Higher risk of fire 
• Longer drying times
• Higher utility bills
• Shorter dryer life

Typically, Quality Air Ducts dryer duct cleaning service includes disconnecting the dryer from the wall and inserting a rotating brush through the duct that runs from the dryer location in the house to the dryer duct discharge location on the outside of the house. This allows the duct to be brushed clean. At the same time the duct is being brushed, a vacuum and blower system is attached to the ductwork to assist in carrying the lint out of the duct. In some cases the duct may be full of water and must be pumped out with a different system
