Your HVAC System
A conventional HVAC duct system consists of a supply duct system to carry heated or cooled air from the furnace/air conditioner to various parts of your home , and a return duct system to bring fresh air back to HVAC System to be redistributed again. The supply network consists of a main duct, which carries air to smaller branch runs, which carry air to the desired vents. The return network works in reverse.
The Mad Hatter HEPA-AIR Cleaning Process
- The Mad Hatter cleans your air ducts using state of the art compressed air tools and brush systems. We dislodge dirt, dander, dust and other contaminants from your ductwork and HVAC components.
- We use a powerful HEPA-filtered vacuum collection system to pull dislodged contaminants out of the duct system.
State-of-the-Art Source Removal Duct Cleaning Process
The HEPA-AIR process utilizes a HEPA-AIR portable power vac in tandem with a specially designed AIR-SWEEP portable air compressor and agitation tools for efficient state-of-the-art source removal duct cleaning. This method enables our professional duct cleaners to remove contaminants from all parts of the duct system, regardless of location or type of duct. This process requires a limited amount of access holes.
Here’s how it works:
- The supply and return networks are “zoned,” or separated, so they can be cleaned independently. This is typically done by removing the furnace filter, inserting it into a plastic bag and reinserting it into the furnace.
- An access hole is cut into the supply plenum and the flex duct from the HEPA-AIR vacuum inlet is connected to the plenum with a quick-connect attachment collar. The powerful vacuum creates high velocity air movement within the supply ductwork to transport loosened dirt and contaminants out of the ductwork and into the vacuum’s filtration/collection system.
- Each branch is cleaned separately starting with the branch farthest from the vacuum. The register and boot areas are blasted with compressed air from the AIR-SWEEP compressor using the special air booster gun to push any dirt or debris into the branch run.
- The branches are then cleaned by feeding the forward AIR-SWEEP assembly down each branch run to push dirt and debris forward into the main run. The branches can also be cleaned using the reverse AIR-SWEEP if access to the branch duct is available at the main supply duct.
- Agitation devices such as the AIR-SWEEP Power Brush or Duct Whip are also used to dislodge caked on debris from inside duct surfaces.
- The main run is then cleaned using the agitation devices and the reverse AIR-SWEEP assembly to dislodge debris accumulated on duct surfaces. The loosened debris is pulled backward toward the HEPA-AIR portable power vacuum and captured in its multi-stage filtration/collection system. One-inch diameter access holes need to be cut only every 25 feet.
- Once the supply side of the system has been completely cleaned, the return duct system is cleaned using the same method. Once the entire cleaning process is completed, all access holes are completely closed with the efficient caplugs and insulated spin doors that seal off any leaking and make the duct systems easily accessible for repeat cleaning.
|“If it’s in your air ducts…it’s in your lungs.”Why do air ducts need cleaning?
Dust, pollen, mold spores, fibers, hair, paper dust, and more are drawn into your HVAC system. 95% of these particles pass through the air filters, hiding in the air duct system and air handling equipment. This buildup can reduce air flow up to 50%. The air ducts are breeding areas for bacteria and molds that cause many people to suffer from allergies or respiratory stress. This can be a source of musty, stale odors.When should they be cleaned?
