The Air Duct Cleaning Process

Learn the basic air duct cleaning process and how it can help maintain your ventilation system.

Understanding air duct cleaning process is important so you know what to expect during a cleaning procedure. You should also understand how the air duct cleaning process is conducted so you can rest assured that the air getting into your lungs is of the highest quality possible.

As an example, if the contractor uses a sealant to prevent mold growth, you should know that this is a bad solution that will endanger you in the long run. They need to get rid of the mold permanently so you can enjoy breathing fresh air all day long.

Let’s take a closer look at the actual air duct cleaning process.

Step 1: The Inspection

First and foremost, the contractor needs to conduct a prior check of your air inflow system. This helps to identify the actual problem and gives you clear insights into the ductwork and ventilation system. Your air duct cleaning service provider may offer you quick suggestions for improving the airflow performance and for lowering your energy bills, such as sealing the air leaks, replacing clogged filters or improving various aspects of the system.

During the inspection, the contractor might also detect certain issues about potential mold problems that need to be fixed before they start the actual cleaning process. Note that if your ductwork is entirely made of sheet metal ducts, the contractor can use a biocide for sanitation purposes. Conversely, you cannot use this solution if your ductwork is made of fiberglass or has fiberglass lining.

Step 2: Creating Negative Pressure

The second step of the process involves using compressed air, or negative pressure, to remove any debris, dirt or dust from the ductwork. The exhaustion pipe needs to be connected to the exterior so all pollutants and viruses from your air are not sent back into your home. This step is paramount before doing the actual mechanical cleaning.

Step 3: Cleaning the Ductwork

Now the actual fun begins. At this point, the contractor will use specialized tools, including cable driven brushes and long nylon brushes, to clean your ductwork. The return registers are also cleaned and vacuumed to ensure they have no dust or debris on them. The damaged fiberglass insulation is repaired using sealants.

Step 4: Cleaning the Remaining Components

The contractor will clean all the remaining components of your HVAC system that connect with other components through your ductwork. The list includes:

  • Blower blades
  • Grills
  • Diffusers
  • Combustion chamber
  • Coil drain pan
  • Both sides of the cooling coil
  • Humidifier

In order to clean certain components, the contractor might use an EPA-approved sanitizer.

Step 5: Checking the Results

The last step of the air duct cleaning process involves doing a visual check of the entire system. You need to ensure that all the registers, air vents, and diffusers look clean. You should also check the system operation in both cooling and heating modes, to ensure that everything goes smooth. Now you can rest assured knowing that you won’t expose yourself to any kind of air-related problems.
