How Air Duct Cleaning Works

How Air Duct Cleaning Works

Air duct cleaning can remove allergens, dust mites, pet dander and other debris that build up in your ventilation system over time. This can help reduce allergy and asthma symptoms and prevent pollutants from circulating throughout your home. Cleaning your air ducts can also help reduce your energy bill by allowing your heating and cooling systems to operate more efficiently. Stanley Steemer offers professional duct cleaning services that include a comprehensive whole-system clean and inspection to identify potential issues with your ductwork.

A qualified air duct cleaning Dallas technician will first inspect your vents, registers and ductwork to ensure they are accessible for cleaning. They may use a flashlight, mirrors and duct tape to check for leaks, disconnected parts, or structural concerns. They may also use cameras to examine hard-to-reach sections of ductwork. The technician will then determine the proper method for sanitizing and cleaning your ductwork.

If your ducts are insulated, they will need to be inspected for mold growth before the cleaning process can begin. In many cases, mold growth is a sign that the ducts are not properly sealed or insulated and must be corrected prior to any duct cleaning or replacement. If a professional finds mold, they will likely suggest a thorough cleaning to eliminate the spores and then replace the insulation.

Before the cleaning process begins, the technician will hook up the vacuum collection device’s large hose to the air handler, typically located in the basement, garage or attic. They will then cover each air register with an adhesive covering and seal it. If the ducts are not accessible, the technician may need to cut an access hole in the ductwork for the hose to reach the air handler.

Once the vacuum collection device is connected, it will create negative pressure inside the ductwork. This will suck dust, dirt and other debris into the collection device, where it will be contained until it’s ready for disposal. This is an important step that separates NADCA-certified contractors from fly-by-night scam artists who have been known to quickly vacuum and then blow the dust back into your living space.

Some air duct cleaners will recommend the application of chemical biocides or sealants to the interior surface of your ducts. These products are designed to kill bacteria (germs) and fungus, as well as prevent future biological growth. While they may be effective in certain circumstances, it’s important to understand that these same products are registered for use on hard surfaces and can reintroduce allergens and contaminants once the ducts are cleaned or resealed.

The most effective approach to duct cleaning is to utilize high-powered vacuum equipment. The vacuuming process should be performed by a NADCA-certified technician who will follow a set of best practices to ensure that your ductwork is thoroughly cleaned, and that any potential leaks are repaired before the system is turned back on. This can also provide a better opportunity for a post-cleaning blower door test, which can further identify leaks and verify that the system is operating correctly.
