Read MoreAir Duct Cleaning is the removal of containments from your ductwork. Your Air Ducts are conduits or passages used for heating, ventilation, and air conditioning to deliver and remove air throughout your home. Air Ducts become contaminated with dust, mold, dirt, construction debris, bacteria, dust mites, soot, nicotine, pet dander and debris as a result of standard living, construction, renovations, pets, smoking, dead skin cells, etc.
The containments that infiltrate your ductwork will build up overtime. As air passes through your ductwork, it is circulating those containments throughout all areas of your home. In fact, air circulates throughout your home up 5 to 7 times per hour, which means those same containments composed of dust, mold, dirt, construction debris, bacteria, dust mites, soot, nicotine, pet dander and debris are being transported and circulated too.
Additionally, the build up of containments in your ductwork restricts air flow causing your HVAC system to work harder and shortening its life span.







Have your air ducts been cleaned in the last 3 to 5 years?
Do you smell a musty odor especially when your HVAC system is turned on?
Have you completed constructions or renovations recently?
Are you unable to get rid of a pet, nicotine or other odors?
Do you see visible dirt or mold on your vent covers/surrounding areas?
Do you have allergies, asthma and/or feel like you are always sick?
Have you moved into a new home?
Are you dusting daily?
If previous home owners had pets of smoked cigarettes, these odors will linger long after they leave. Cleaning the carpets and/or priming/painting the walls will help eliminate these odors; however, in many cases, it will not eliminate them. That’s where duct cleaning comes in! Dust within your ducts hold smells such musty odors, nicotine, pet odors and/or numerous other smells. We clean and treat the HVAC system with an Antimicrobial to rid these odors once and for all.
There are some key indicators that you can visibly see to tell you if you have poor indoor air quality within your home:
IF VENT REGISTER COVERS LOOK LIKE THE IMAGES BELOW, YOU NEED AN AIR DUCT CLEANING!





Run 8-inch vacuum line to the supply and return trunk line of your home, which puts the system under negative vacuum.
Remove and wash all vent covers.Remove and wash all vent covers.
190 pounds of force per square inch (psi) of compressed air and/or air charge dislodgers are brought to every single vent in your home to force all dust and debris back to the main trunk line.
Air charged dislodges are then sent down all main trunk lines to dislodge all dust and debris as the negative vacuum pulls contaminants back into the vacuum truck.
Finally, your HVAC system is treated with an anti-microbial treatment utilized to kill any mold or bacteria.
A good rule of thumb is to clean your ducts every three to five years according to the National Air Duct Cleaning Association (NADCA) This is the minimum, as this is the length of time that it can take for your air ducts to fill back up with dirt, dust and other debris after a thorough cleaning. However, some homes may require more frequent cleanings. According to NADCA, you may want to have your air ducts cleaned more frequently if you:
It is a common misconception that air duct cleaning will distribute dust and debris throughout your home during the cleaning process. Consumers are concerned that their home, furniture, and contents in their home will be left covered in dust. This is ONLY the case when proper equipment is not used to complete the job.
At NJ-Advanced-Air Duct, we use 16,000 CFM power vacuum trucks. The vacuum power is strong enough to ensure that no dust or debris comes back into your home. The containments are pulled back into the truck- leaving no new mess behind.
To become a member of NADCA, the air duct cleaning company must meet specific requirements including having Certified Air System Cleaning Specialists (ASCS) on staff.
An ASCS must pass the NADCA certification examination, demonstrating extensive knowledge in HVAC design and cleaning methodologies. Additionally, they are required to maintain their certification through annual continuing education.
All NADCA members are required to sign a code of ethics agreeing to protect you the consumer and follow of standards set forth by NADCA.
The average cost of a proper single HVAC system air duct cleaning by NADCA and EPA standards typically runs from $400 to $1000 depending on the size of the home.

As a general rule, for every dollar spent on preventative maintenance, you will save at least five dollars in subsequent expenses. Studies by General Motors and 3M both state that spending one dollar on preventative maintenance could save you anywhere from 7-35 dollars including but not limited to: lost production, added inventory, labor, parts duplication and equipment redundancy.
“An ounce of prevention is worth a pound of cure” Benjamin Franklin
