You’ve seen the signs that your air ducts need cleaning, but now are you wondering how air duct cleaning is done? What do you need to be prepared for?
Duct Cleaning Process
Step 1: Inspect The Air Ducts
Before any duct cleaning begins, a thorough inspection of your ductwork is important.
We recommend the homeowner conduct a quick, visual inspection of the ducts leading to the return and supply registers. Check the level of buildup in the ducts so you can see the difference after the ducts have been cleaned.
Bridge City Duct Cleaning will also inspect the ductwork using specialized cameras. They will check for blockages, mold growth, leaks or, in the case of flexible ducts, kinks. This is a good time to repair and replace damaged ductwork.
Step 2: Prepare the Home
Bridge City Duct Cleaning uses large, portable or truck-mounted vacuum collection devices to suck dust and debris out of your ductwork. However, before turning on the suction and scrubbing the ducts, the technicians must perform preliminary steps.
First, they hook the vacuum collection device’s large hose to a duct close to the air handler—the heart of your HVAC system. The technician cuts an access hole in the duct, inserts the vacuum hose, and seals where they join as tightly as possible.
(Note that your HVAC system has a supply and a return side—ducts that send treated air into the rooms of the house, and ducts that return air to the air handler. The supply and return sides are separate, and the duct cleaning process is performed on each.)
Next, the technician will seal each register with an adhesive cover. This is an important step because even an extremely powerful vacuum collection device will not work if the registers in each room of the house are uncovered.
Step 3: Create Negative Pressure
Once the technician finishes these steps, they turn on the vacuum unit. This step creates negative pressure, and particles inside the ductwork will be sucked into the collection device as they are brushed or blown loose.
