STEP 1

We arrive at your home with a Power Vacuum Truck (we will need space in your driveway for the truck)

STEP 2

Uniformed Technician, certified by NADCA, introduces himself and presents his identification

STEP 3

To protect floors and carpeting, shoes are removed or covered with booties if required by weather or customer preference

STEP 4

Technician does a walk-through with the owner to assess the layout, describe the work to be done, and answer any questions that arise

STEP 5

We run the heating and cooling equipment through a cycle to verify that it is operational

STEP 6

Technician determines air duct layout and evaluates accessibility

STEP 7

Access openings, if needed, are created in solid ceilings such as fixed tiles or drywall

STEP 8

Technician lays out protective coverings on sensitive flooring or carpet across which the vacuum hose will be routed

STEP 9

Technician unloads lengths of vacuum hose and other equipment that will be needed on the job

STEP 10

Vacuum hose is laid out from the Power Vacuum Truck, into the house and over to the furnace area

STEP 11

Technician closes or covers all registers to prevent ‘blow-back’ during the cleaning

STEP 12

Technician creates an 8” circular access opening in both the supply main and the return main. These are the openings to which the vacuum hose will be attached during cleaning.

STEP 13

Technician places our exclusive live video Duct-Cam® inside a main air duct and shows you the air duct interior on a monitor before the air duct cleaning, deordorizing and sanitizing begins.

STEP 14

Vacuum hose is attached to either the supply main or the return main. The two sides of your system are cleaned separately.

STEP 15

Truck is started and the vacuum is engaged to create a strong air flow throughout your air duct system. The vacuum-induced air flow continues during the entire air duct cleaning process.

STEP 16

Technician goes to each register in your home and uses a special air nozzle (connected to a 200 psi air compressor mounted on the truck) to flush dust and debris downward toward the vacuum

STEP 17

Floor registers and the ducts leading to them are also flushed out by the skilled application of the 200 psi stream of compressed air

STEP 18

In the basement the Technician uses cutting tools to create a series of smaller access openings in the air ducts for the continued use of agitation tools to loosen dirt and debris so the air flow can carry it to the vacuum hose.

STEP 19

Agitation tools such as whips and air snakes must be run back and forth across every square inch of every interior surface in each duct. The loosened dust and debris is then carried by the air flow down to the vacuum hose and out to the truck where it is captured.

STEP 20

Technician assembles a power-driven rotary brush tool. The brush head is always cleaned and sanitized before use.

STEP 21

Even though agitation tools have already been skillfully applied to every duct surface, the Technician then takes the extra step of applying the rotary brush throughout both the main air ducts.

STEP 22

The furnace blower and blower compartment are then accessed and cleaned

STEP 23

To insure a thorough cleaning, the technician first removes the blower from the blower compartment if possible

STEP 24

If the system has air conditioning, the plenum (usually just above the furnace) is opened to give the Technician access to the evaporator coil of the air conditioning system.

STEP 25

Technician air washes and vacuum cleans the evaporator coil and the drain pan beneath it

STEP 26

If the job includes it, the Technician then cleans the burners, the combustion chamber and the interior of the heat exchanger on the furnace

STEP 27

The Duct-Cam® is then placed back in the main air ducts so the Technician can show the now spotless interior on the monitor.

STEP 28

One-inch access openings are sealed with injection molded pop-in plugs.

STEP 29

Larger access openings are sealed with custom made sheet metal plates secured by self-tapping screws to return air ducts to a like-new condition

STEP 30

Technician reassembles all components.

STEP 31

Technician runs heating and cooling equipment through a cycle once again to verify that it is operational

STEP 32

If the customer has a clean replacement filter the Technician installs it (Safety King does not reinstall dirty filters and does not sell or carry replacement filters).

STEP 33

Technician applies a service sticker showing date of air duct cleaning, deordorizing and sanitizing, Technician names, and suggested date for next air duct cleaning, along with recommended filter type and size information.

STEP 34

All equipment and supplies are removed from the jobsite and stowed on the truck

STEP 35

Air Duct Technician conducts a final walk-through, requests customer signoff and payment, and departs.
