Let’s start off by defining what is an air duct. It’s nothing but a set of channels that guide air through your ventilation, air conditioning, and heating system to different parts of your home: 

• Central vacuum system

• Air exchangers

• Dryer ducts

• Heat recovery ventilators

• Wall-mounted ventilation unit

• Central ventilation system 

Over the years, the listed ducts will become defective on account of a build-up of dust, hair, fur, debris, etc. Here’s why it’s important to understand the duct cleaning process. Note that cleaning a house’s ventilation duct should be done every three years at least, five years for air exchangers, to ensure proper functioning. Several factors must be considered first to establish the best maintenance plan, such as:

• Where the house is located (metropolitan area or countryside)

• Size of your house and the number of individual rooms

• Take into account the number of dwellers

• Note the presence of pets, whether the kitchen has a range hood, etc.

After noting the information above, you can, moving forward, call in a trade professional.

For proper residential air duct cleaning, you can opt for an SFP process, which is a three-step procedure featuring the following:  

• S is for suction: It entails fully halting the duct’s functioning, opening it and then cleaning it. It may be hazardous for you to carry out maintenance while it’s functioning.

• F is for friction: This means spotting all elements that may hinder the proper workings of the ducts.

• P is for pulsion: This step consists of dislodging all debris from the ducts using a vacuum nozzle.

Should you want to carry out the cleaning yourself, here’s a list of materials you’ll most definitely need:

• Step stool

• Ladder

• Screwdriver

• Protective goggles

• Mask

• Inspection mirror

• Vacuum

• Flashlight

• Bucket with soap and water

• Gloves

And here’s a list of steps to follow:

• Shut off your ventilation system;

• Remove and clean the vent grilles and return vent grilles;

• Use a scrub brush to clean the inside of the air ducts to dislodge all dust and debris;

• Then clean the filter connected to the grille;

• Use your flashlight to check if there’s any remaining dirt. 

Check again with the mirror and flashlight to make sure the ducts were cleaned properly. Should this not be the case, hit them again with the vacuum. After wrapping up the cleaning process, reinstall the filters and the grilles, and then turn the ducts back on.
