Duct Cleaning

Since much of our time is spent inside, the reality is that indoor air pollution has become an issue that can no longer be ignored. Indoor air pollution represents a significant health problem for people suffering with allergies, respiratory ailments, such as asthma and emphysema, immune system deficiencies and other chronic illnesses.
An important aspect of improving your home’s air quality is the maintenance and cleaning of the heating and cooling systems. Typically, this is called duct cleaning and involves cleaning the supply and return air ducts of forced air systems. In addition, the registers, grilles, diffusers, heat exchanger coils, drip pans, fan motor, fan housing and air handling unit housing are cleaned.

The type of contaminants usually found inside air duct systems include, dirt, dust, dust mites, drywall dust, mold, mildew, fungi, moisture, sawdust, pet hair, pet dander, insect remains, pollen, carpet fibers and/or rodents. These contaminants can be effectively removed with a thorough professional duct cleaning by Enviro-Clean. Our professionals are trained and licensed to rid your home of these potential health hazards. Let us help you and your family breathe easier.


The Enviro-Clean Method
State-of-The-Art Source Removal Duct Cleaning

The definition of source removal duct cleaning is as follows: Cleaning the air conveyance system using compressed air tools and mechanical agitation devices to dislodge dirt and other contaminants from the ductwork andFiltration Unit for Duct Cleaning with Hepa Filter other HVAC components, and a powerful HEPA-filtered vacuum/collection system to pull these contaminants out of the duct system and capture them.

This method utilized a HEPA filtered portable power vacuum in tandem with a specially designed portable air compressor and agitation tools for the efficient state-of-the-art source removal duct cleaning. This method enables our trained personnel to remove contaminants from all parts of the duct system, regardless of location. Yet it is simple to perform and required only a limited amount of access holes. It works as follows:

1. The supply and return networks are “zoned,” or separated, so they can be cleaned separately. This is typically done by removing the furnace filter, inserting it into a plastic bag and reinserting it into the furnace.

2. An access hole is cut into the supply plenum and the flex duct from the 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.

3. 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 compressor using the special air booster gun to push any dirt or debris into the branch run.

4. The branches are then cleaned by feeding the forward agitator assembly down each branch run to push dirt and debris forward into the main run. The branches can also be cleaned using the reverse process if access to the branch duct is available at the main supply duct.

5. Agitation devices are also used to dislodge caked on debris from inside duct surfaces.

6. The main run is then cleaned using the agitation devices and the reverse assembly to dislodge debris accumulated on duct surfaces. The loosened debris is pulled backward toward the HEPA portable power vacuum and captured in its filtration/collection system. The 1” access holed need to be cut only every 25 feet.

7. Once that supply side of the system has been completely cleaned, the return duct system is cleaned using the same methods.

8. At this stage, the coil, motor and blower, and blower compartment are cleaned.

9. Once the entire cleaning process is completed, all access holes are completely closed and sealed per ASHRAE standards to prevent any air leakage.

10. At this stage, all the supply registers and return grilles are hand-cleaned and sanitized before reinstallation.

11. The final step is to apply a specially formulated anti-microbial sanitizer that effectively kills bacteria and acts as a deterrent to future microbial buildup.
