Duct Cleaning and Sanitizing

Do you suffer from respiratory illnesses, sinus problems, headaches or allergies? Do you have musty odors or see excessive dust on your vent covers and furniture? Over time, air ducts can get clogged with dust, dirt and biological contaminants, such as mold, dust mites and bacteria. We are certified by the National Air Duct Cleaners Association (NADCA) to perform professional duct cleaning on commercial and residential properties. This certification program ensures the property owner that we possess the required knowledge and expertise to perform this service in a professional and competent manner.

A thorough cleaning and sanitizing of your air duct system will reduce sources that aggravate health problems. We inspect and clean the entire duct system.

See before and after photos of what we can do to your ductwork.

Preparation
Prior to beginning any work, we will cover all items in the work area with plastic sheeting, cover all grills, registers and diffusers with disposable filters and shut off and lock out the system. This prevents any dust from escaping during the cleaning process.

Cleaning
The interior surfaces of the duct work shall be cleaned utilizing a combination of a mechanical brush system and high pressure air washing methods under negative pressure, also known as the "push and pull" method. This is achieved by isolating a particulate section of duct work via inflatable zone bags, then attaching vacuum units capable of producing 5,000 cfm at two inches of static pressure, which are equipped with HEPA filters that are 99.97% efficient at filtering particles down to three microns in size, thus creating a jet stream of air. Two-inch holes are then drilled into the isolated ductwork every ten feet, where air whips forward and reverse, propelling skipper balls down the ductwork to agitate debris up into the air stream. An air compressor producing 19.6 cfm at 185 psi is utilized for maintaining adequate air washing pressure. Subsequent to source removal, a sanitizing agent is fogged into the system. If necessary, all turning vanes and system components shall be hand vacuumed and chemically washed.

Sanitizing
Using UL-listed fogging equipment, AAQ will inject an EPA-approved & registered sanitizing agent throughout the system, subsequent to source removal. This sanitizing agent primarily is utilized for killing bacterial and fungal growth which may exist in your air ducts.

Inspecting the system
All surfaces must be visibly clean, as outlined by the National Air Duct Cleaners Association (NADCA ACR-2005). The NADCA vacuum test is available upon request.

New Filters!
For our residential customers, AAQ will remove the existing filters and replace them with new, LifeTime Filter® electrostatic air filters for an additional fee. AAQ is an authorized dealer of these filters and will install them as part of our service. Like the name says, they have a lifetime warranty.  Once the entire system is allowed to dry, the system will be restarted and the work area will be returned to its original condition.

Start 'er up!
Prior to reactivation of the system, all access holes shall be sealed with Duct-Mate^® reusable access doors upon request, otherwise sheet metal patches will be installed. The disposable filters shall remain in place for 24 hours to capture any foreign debris. After that time period, the filters will be removed and discarded. The work area will be cleaned, vacuumed and restored to its original condition.

Your report
After 10 days from the completion of the project, AAQ will deliver a report that includes the NADCA vacuum test results, before and after photo documentation, observations and recommendations.
