10 Steps to a Professional Air Duct Cleaning

Step 1 – Start With The Right Equipment

Our “Monster-Vac” trucks create the negative air flow needed to remove even the worst contaminants and pull them outside where they belong.

Step 2 – Protecting Your Home Or Business

A complete and in-depth cleaning requires us to go into every room that contains an air duct or cold-air return.

At Fresh Air, the work will not begin until the floors, doorways and outside wall corners are protected.

Slip-on shoe covers, safety mats and plastic corner guards create a barrier between our equipment and your home.

Step 3 – Super-Vac

Access to the bonnet and main trunk lines allow us to cover and protect the A-Coil, connect the 8″ vacuum hose and create the massive negative air flow needed to remove the dirt, dust and contaminants that are hiding in the system.

Step 4 – Wet Spray And Hand Clean

The metal box under the floor register is called a “stack-boot.”  We remove and wipe the register, spray a mild degreasing agent on the surface and then clean each one with a soft cotton towel.

Step 5 – Maximize The Vacuum

Once the 8″ hose is connected to the system the huge vacuum fan on the truck begins pulling air from the living spaces down through the duct work.

By covering the registers a negative pressure is created within the system so dirt and dust can’t puff back into the living spaces.

Step 6 – Scrubbing The System

Pulling large volumes of air toward the truck, we now feed our soft rubber, high pressure scrubbing tools down each of the supply lines.

This removes every trace of dirt, dust, pollen, chemical residue and pet dander that has collected over the years.

Step 7 – Cold Air Return System

After all of the duct work on the supply side is completed, we move to the cold-air return system runs.

The main return grill is removed and cleaned followed by the covers and lines throughout the structure.

Step 8 – Trunk Lines And Plenums

We now access the inside of the trunk lines (supply) and plenums (return air) and clean each one with specialized scrubbing tools.

Small 1″ holes allow access to every area as the dirt is pulled toward the attached vacuum hose.

Step 9 – Furnace Interior

This optional step is completed with the removal of the furnace panels and cleaning of the blower fan, combustion chamber, electric motor and cabinet.

The filter is air swept and vacuumed before being reinserted or exchanged with an owner-supplied replacement.

Step 10 Wrapping It Up!

New galvanized access panels are installed over the openings created for the vacuum hose and sealed with aluminum tape.

Air dampers are put back in their original position, plastic plugs are inserted in the 1″ access holes and all debris is removed.
