The Process

Here is the process of the AC duct cleaning:

Step 1: Inspection

A straightforward, visual examination of the ducts is significant for two reasons. To begin with, it’s a stage that you can take yourself get to survey the degree of problem with your AC Ducts and affirm the distinction after they’ve been cleaned. The Company you hired will probably have cameras that can go significantly farther into the ducts and show the full degree of the development before cleaning.

Step 2: Preparation

Duct cleaning companies usually use RotoBrush machine which is great both in terms of scrubbing the dirt, debris, and mold inside the ducts while vacuuming it off simultaneously.

In any case, before turning on the machine and cleaning the air ducts, the professionals must play out a couple of prior steps.

First of all, an appropriate opening in the duct is found. Then the hose is prepared. The expert technician identifies the brush size and type according to the duct nature, size, and shape. There are both soft and stiff bristle brushes, soft brushes are used for all types of ductwork including flex duct board and sheet metal ducts.

The stiff bristle brushes are only to be used on sheet metal ductwork because they are too aggressive for flex duct or fiberboard ducts. Majority of the expert technicians will use the 8-inch brush to clean the majority of smaller supply air ducts; whereas for larger ductwork they use a brush 2 to 4 inches larger than the height of the duct.

When cleaning rectangular ducts, they will use a brush 4 inches larger than the height of the duct for example in a 10-inch high rectangular duct they will use a 14-inch brush. For more info, you can always ask for the manual which provides additional tips on brush sizes and cleaning techniques.

Lastly, in the preparation process, the surfaces in the proximity of the cleaning are covered with plastic especially the furniture.

Step 3: Cleaning of Ducts

Now the hose is inserted inside the duct while simultaneously turning on the rotation and vacuum. This cleaning is performed for almost 30 to 45 min for a single unit.

Step 4: Sanitization of Ducts

Now the EnviroCon sanitization liquid is loaded up into the foger via lubricant gasket. Then the ducts are sanitized by spraying the mist of sanitizer into the ducts to prevent the growth of bacteria and make the air a lot cleaner.

Step 3: Clean-up

Now everything is put back together as it was previously, as well as, everything is cleaned and left a lot cleaner than before.
