AC is one area of a home that can often be forgotten when it comes to cleaning. Duct cleaning removes dirt, dust, and other debris from these pipes to improve the air quality in your home.

A professional duct cleaning company will use powerful vacuums and brushes to clean your ducts, removing all the dirt, dust, and debris built up over time. Here are the processes that take place in a duct cleaning.

Step 1: Removal of All Possible Supply and Return Registers and Grilles.

This allows access to the entire duct so that every nook and cranny can be properly cleaned. Removing all the registers and grilles also allows for more thorough cleaning of the AC system. Every system component can be reached and cleaned, ensuring it will operate at peak efficiency once everything is back in place.

Step 2: Cleaning the Registers and Grilles.

To clean the registers and grilles properly, you will need to use a vacuum cleaner with a hose attachment. First, remove the register or grille from its mounting. Next, vacuum the surface of the register or grille using the hose attachment. Finally, wipe down the surface of the register or grille with a damp cloth.

Step 3: Cleaning All Possible Supply and Return Ductwork, Including the Truck Lines.

This step will remove any build-up of dirt, dust, pollen, or other allergens that could be causing problems for your indoor air quality. Not only will this increase the efficiency of your system, but it will also help improve your air quality and prevent any potential health problems that could come from breathing in contaminated air.

Step 4: Sanitize the Ductwork to Remove Any Mold, Spores, and Bacteria.

This is an important step in preventing mold and mildew growth and keeping your home’s air quality clean. There are a few different ways to sanitize your ductwork, but one of the most effective is using a bleach and water solution. Simply mix one cup of bleach with one gallon of water, and then use a brush or sponge to apply the solution to the inside of the ductwork. Be sure to reach all areas, including any corners or crevices.

Step 5: Installation of the Clean Supply and Return Registers and Grilles

This is a simple process that requires only a few tools. The first step is to remove the old register or grille. Next, measure the opening to ensure that the new register or grille will fit. If necessary, trim the new register or grille to size. Once the new register or grille is the correct size, install it using screws or nails. Finally, reinstall any screws or nails removed during the installation process.
