Ducting cleaning can contribute to serious health problems, especially for those with asthma, allergies or other respiratory conditions. The National Air Duct Cleaning Association (NADCA) recommends that homeowners have their ductwork cleaned regularly to improve indoor air quality and promote healthy living.

A reputable air duct cleaning company will use a negative pressure system to thoroughly clean your home’s ductwork. First, they’ll use a brush to dislodge any dust or debris from the inside walls of the ductwork. Then, they’ll use a high-powered vacuum to suck up all of the dust and debris.

This method is the most thorough way to clean your ducts, and it’s also the safest. However, it can take three to five hours to do a complete cleaning job. If you want to speed up the process, ask your duct cleaners if they offer a power wash with their cleaning service.

Ensuring Hygiene Standards: Best Practices for Ducting Cleaning

Some duct cleaning companies may also suggest that you allow them to apply chemical biocides or sealants to your ducts. These chemicals can kill bacteria, fungi or mold and prevent future biological growth. Before allowing any company to treat your ducts with biocides or sealants, you should fully understand the pros and cons of this approach.

Remember, any ductwork cleaning work should be done by a certified and insured professional. The technician should be able to show you before and after pictures of their work, and they should explain the entire process to you. Make sure you give them easy access to your air handler and plenums, which are usually located next to the furnace in the attic or basement. Also, don’t schedule the appointment during the baby’s nap time or an important Zoom meeting because your duct cleaner will be making loud noises.
