What You Should Know About Air Duct Cleaning

Air Duct Cleaning removes built-up dust, dirt and debris from your home’s ductwork system. This is done by an experienced technician who utilizes brushes, air compressors, power vacuuming equipment and other tools to dislodge debris and contaminant particles from surfaces and crevices of your ductwork. This process is often combined with sanitizing, which uses chemicals to kill bacteria and mold that could be growing on or in your ductwork system.

A professional will inspect your ductwork for problems such as leaks, kinks and loose connections. If they are found, the contractor will recommend repairs or replacement, as necessary.

In order for the contractor to access the ductwork, it is important that all vents are clear and not blocked by furniture or other objects. The technician will also need to be able to easily locate the air handler and plenums, which are typically located in the basement or attic of your house. Once the technician has a clear path to the ductwork system, they will begin cleaning. They will start by agitating all accessible areas of the ductwork to dislodge any debris that has settled there. This is followed by creating negative pressure inside of the ductwork so that the contaminated debris can be removed without being released into your living space.

Once the ducts are clean, they will be vacuumed using a powerful truck-mounted vacuum that can capture even the smallest particles of dirt and grime. This is usually the most time consuming part of the entire cleaning process. It is not unusual for a skilled and certified NADCA Air Duct Cleaning technician to spend between three to five hours completing this portion of the cleaning process. A less experienced or uncertified technician may be able to finish the job in half this time, but you should expect this to result in a substandard cleaning job.

After the ducts are vacuumed, the technician will check for any debris or contaminants that were not able to be dislodged with the brushing and agitating tools. They will then sanitize the ductwork with chemicals to kill any bacteria and mold that may be growing there. This step can be very dangerous for individuals with respiratory conditions or auto-immune disorders, as it can cause severe irritation to the lungs and other sensitive parts of the body.

Air duct cleaning is not an absolute necessity for everyone, but it can be a good idea if you or someone in your household suffers from chronic respiratory issues such as asthma or allergies. Poor indoor air quality can aggravate these symptoms and lead to a wide range of other health problems, including fatigue, dry eyes, nose and throat and headaches. In addition, dirty ductwork can contribute to the spread of harmful bacteria and viruses throughout your home. An effective air duct cleaning and sanitizing procedure will improve the quality of your indoor air, making it safer for all members of your family.
