Air Duct Cleaning Method & Equipmentair duct cleaning


You may be saying, “Wait there’s more than one air duct cleaning method?” Yes, there’s a few different air duct cleaning methods, but only one correct way to ensure a great cleaning! According to N.A.D.C.A, “There are two key components to HVAC cleaning: breaking contaminants loose, and collection of contaminants.” This air duct cleaning method is referred to as “Push-Pull.” 


Another question you may have, “What am I looking at in these pictures above?” Great question! Remember how N.A.D.C.A mention the two key components: agitating & extracting? This is a collage of our big equipment. The two pictures on the bottom right are air duct cleaning machines. These machines provide the negative air suction that is applied to an HVAC system. Lastly, the bottom left picture is our high powered gas air compressor. This air compressor provides strong air to push all contaminants.

Agitate & Push

On the contrary, how do you break contaminants loose? Phenomenal question! As a matter of fact, rods are connected to the air line, air line is connected to the air compressor, and agitation tools like whips are attached. Highly recommended in the air duct cleaning industry is a minimum of 175 P.S.I (Pound force per square inch) and lets not forget C.F.M because the air needs to fill the tank at a high rate to generate enough pressure to break contaminants loose. I would say our industrial gas air compressor exceeds industry standards with 200psi and 32cfm. 

Pull & Suction

The red machine, which looks really small in the picture actually is quite big weighing close to 400 pounds. The “Ranger”is the strongest gas portable air duct cleaning machine in the world. It has a 31HP Van Guard motor that generates more than 7,000+ C.F.M & has 12-24 inches of static lift. 

Comparatively, the two gray machines on the bottom right are electric portable air duct cleaning machines. The “220 REVOLUTION HYBRID DUCT VACUUM” is the strongest electric portable air duct cleaning machine in the world with 5,000 C.F.M filtered air. According to Hypervac Technologies, “The 220 Volt Hybrid Offers double the suction of most other portables, meaning you will get suction comparable to what many duct trucks are providing at the furnace.”

Cleaning Chemistry

Furthermore, according to N.A.D.C.A, “A minimum of 4,000 C.F.M (Cubic Feet per Minute) of negative air suction is needed to extract loosened contaminants.” Equally important, the gas air compressor power to agitate, push debris, to be collected by our duct machines. Finally, there’s a science behind it while one is pushing the other is pulling.

Process, Process, Process!

To emphasize, the importance of the process enough! In detail, we will breakdown the process step-by-step in efforts to be totally transparent. The picture above is a collage put together to provide visuals of what exactly we do.

Before proceeding with setting up to clean an HVAC system we ask for a tour of your home to allocate and count all the air ducts. As well as, a thorough inspection of the HVAC system. For instance, if an issue is detected by technician that prohibits and contradicts the cleaning our job it is our duty to inform the client and make a moral recommendation. Given that the HVAC system checks out, we began to set-up!

Step 1

“Setting Up”

  • First, corner guards are placed on wall corners where the duct hose or air line may rub against. In addition, if front door access is necessary a Seal-A-Door is put in place. Lastly, if needed, roll out rugs to protect floors.

  • Second, most cold air returns and heat registers are sealed and closed off to keep any dust within the system. Sealing the air ducts maximizes the strength of the air duct cleaning machine and contains contaminants. In some cases, there are a few ducts/vents left unsealed because we don’t want to collapse duct work.

  • Second, the air duct cleaning machines or duct hose is carefully taken to where the furnace is located.

  • Third, we cut two two 8 inch holes into the duct work. The first hole we cut is on the plenum above the A-Coil & heat exchangers.

  • Fourth, we protect furnaces by placing an upholstered cushion and a memory foam mat through the 8 inch hole cut above the plenum. Furthermore, the cushion and mat lay over the A-Coil or heat exchangers. This also helps from the blower spinning backwards and to block off the other side of the HVAC system.

  • Fifth, we connect our duct hose to the 8 inch access hole. 

  • Finally, the air duct cleaning machine is turned on and the strong suction is applied to extract and remove dirt, dust, allergens, rodents, rodent feces and other contaminants from the HVAC system.

  • Next, we run airlines from our gas air compressor to the furthest point of a home. Rods are attached to the airline and they’re used as a tool to travel through ductwork.

  • Meanwhile, a technician has attachment tools that connect to the end of the rods. These are tools that help agitate, push, pull dirt, dust, allergens, rodents, rodent feces and other contaminants to the air duct machine.

Step 2

“The Cleaning”

  • To began with, each individual vent is cleaned, from top-to-bottom, using powerful gas compressed air with a whip and forward skipper ball. Contaminants are loosened and pushed to main trunklines. 

    • In addition, the air distribution side is cleaned first. Before we switch over to the intake side of the HVAC system there’s an option to sanitize. As we use the negative air applied to the air distribution side with our air duct cleaning machines suction along with our ULV cold fogger which also has compressed air. Each individual airline is “fogged.” A Botanical is used to sanitize, its active ingredient is Thyme oil. Click here to find out more about the product we use.

  • After, a 1 inch hole is created with a step-bit to access trunklines. Rods are taken in the hole and down the trunkline to agitate with whips. At this point, our air duct cleaning machine is collecting the contaminants. 

  • Lastly, we detach the duct hose and the furnace it’s time to clean the grilles, diffusers, heat exchangers, and the fan motor. They are air washed with gas-compressed air. The A-Coil is air washed with gas-compressed air, vacuumed thoroughly and/or brushed if needed.

Step 3

“The Clean-Up”

  • One inch duct caps/plugs are used to seal the one inch holes cut.

  • The mat placed to protect furnace in the plenum is vacuumed and taken out. Coil bracket is vacuumed and coil.

  • J-Pan/drip pan & blower pan are vacuumed along with furnace panel covers.

  • 10×10 24 gauge duct plates, made by Schneider Sheet Metal, are used to cover the 8 inch holes. Premium Foil UL Listed HVAC Duct Tape is used to seal the duct plate over the 8 inch hole.

  • Everything that we brought in is taken out including trash. Floor is vacuumed around furnace. Lastly, furnace panels are put back on and system is turned on before leaving to make sure everything is properly working.
