Commercial Air Duct Cleaning

Upon arrival we'll inspect your HVAC system, make sure we have access to everything, explain our process & what to expect, finalize the quote and schedule approved cleaning.

1) An 8” or 12” access hole is cut into the main supply line near the plenum. 

2) Block Off the A-Coil to ensure no dust or debris falls into the coil compartment. 

3) An 8” or 12” access is made in the return trunk line near the HVAC system. 

4) The furnace filter is removed, wrapped in plastic, and reinstalled to separate the supply and return sides of the system. 

5) Remove the Blower for later cleaning. 

6) The flex duct from our powerful negative air machine is attached to the supply side of the furnace. (Our negative air machine is equipped with a HEPA filter so we will not be reintroducing dust into your home as we clean.) 

7) Now that the system is running and under negative pressure, we’ll go to each register and seal them off with plastic sheets, foam blocks or cardboard. This will increase your air velocity.   

8) Starting from the furthest register, we will clean each branch line by using compressed air cleaning tools, and/or duct brushes to loosen debris to the main trunk line. The process is then repeated at each register. 

9) Once all the branch lines have been cleaned, we then clean out the main trunk line. All dust and debris are pushed to and captured by our Air Duct Cleaning HEPA Filter System. 

10) The flex duct from our powerful negative air machine is attached to the return side of the furnace.  

11) Now that the system is running and under negative pressure, we’ll go to each register and seal them off with plastic sheets, foam blocks or cardboard. This will increase your air velocity.   

12) Starting from the furthest register, we clean each branch line by using compressed air cleaning tools, and/or duct brushes to loosen debris to the main trunk line. The process is then repeated at each register.  

13) Once all the branch lines have been cleaned, we’ll clean out the main trunk line. All dust and debris are pushed to and captured by our Air Duct Cleaning HEPA Filter System. 

1) The Blower compartment and inside the front of the furnace will be contact-cleaned by vacuuming and wiping down any soiled areas. 

2) Provided we have access, the Blower will be removed and cleaned. Standard cleaning would be to blow it out with compressed air. Heavy buildup may require taking it apart and washing the main components. 

3) Provided we have access, the A-coil will be cleaned. The standard cleaning would be to blow compressed air into the coil compartment while under negative air to remove dust and debris. For more aggressive cleaning a degreaser may be used to dislodge build up. 

4) Once the system has been thoroughly cleaned, we will reseal all access holes with metal patches, then reinstall all registers. 

5) Install a fresh new filter. (If it’s a standard size that we carry, we can provide the filter. Otherwise the client will provide a new filter.) 

After the system has been cleaned, an EPA approved air duct sanitizer/deodorizer may be applied. While the system is still under negative pressure, the sanitizer is sprayed into each register with an Ultra Low Volume (ULV) Fogger.  

*This is an optional, add-on cost, and is only done by request of the client.* 

Dryer vents are cleaned using high pressure, compressed air to blast loose lint, debris, and nests. This important service protects your home from fires, smoke and pollutants. It reduces energy costs allowing dryers to run more efficiently, last longer, and dry clothes faster.  

*This is an optional, add-on cost, and is only done by request of the client.* 

**This is not offered as a stand-alone service, but only as an add-on to a full service cleaning.** 

***At this point we can only offer dryer vent cleaning for ground level openings. ***
