Commercial Duct Cleaning Considerations

You’ve invested a lot of money in the heating and cooling of your commercial property. Don’t skip the cleaning and maintenance of that system. Over time, as the HVAC system does its job of heating, cooling, and moving air, dust and debris degrade its performance. More importantly, when the ductwork becomes dirty, air is filled with particles and allergens and that’s a problem. Therefore, it is important to make commercial duct cleaning considerations a part of your regular maintenance plans.


In a time of nationwide unease concerning airborne viruses, indoor air quality is key to healthy buildings. The spread of viruses, like the coronavirus that causes COVID-19, is a top concern for commercial building owners and managers. However, other dangers exist as well.


Tiny particles circulate through the air inside buildings. These particles include allergens, viruses, bacteria, and molds. A well-running HVAC system filters out most of these particles but a dirty, clogged system does not. In some cases, these particles lead to Sick Building Syndrome. These symptoms go away once the person leaves the building.


Symptoms of SBS include:

  • Throat irritation
  • Itchy skin
  • Dizziness
  • Nausea
  • Fatigue


And look at the bottom line. When systems work harder, energy costs increase and that burns cash. The good news is, commercial duct cleaning is an affordable way to prevent high energy costs and improve building safety. Not all cleaning services are the same, however. There are duct cleaning considerations to make before you hire a vendor.

5 Commercial Duct Cleaning Considerations

Before you hire out your commercial duct cleaning services, ask the vendor some questions and make sure they are NADCA-certified. Check to see if they provide the services listed below.

1. Assessment

Get an overall picture of how your system is doing. An HVAC assessment lets you know what parts need repair and which need replacing and how soon? It tells you how well the system performs and looks at what this costs you. You should schedule an HVAC assessment at least once a year.

2. Commercial Duct Cleaning

Keep HVAC ductwork clean. PURE-Duct is a specialized method that goes inside of the ductwork using high-pressure air turbulence. This pressure dislodges dust and debris which is then removed by a powerful HEPA filter vacuum system.

3. Coil Cleaning

In addition to duct cleaning, the air handling unit and evaporator coils also need attention. The PURE-Steam method destroys bacteria, mold, and viruses. Keeping components clean also cuts energy costs and extends the life of equipment.

4. Building Disinfection

Disinfect rooms throughout the building. If pathogens have spread due to faulty HVAC equipment, PURE-Decon destroys them with a fine mist of hydrogen peroxide and silver. This gets to pathogens at the cellular level to keep them from entering the ventilation system.

5. Insulation Replacement

Repair or replace degraded fiberglass insulation. For repair, the application of antimicrobial paint stabilizes the installation. Replacement with PURE-Cell insulation stops deteriorated fiberglass and other particles from circulating throughout the building.


For a safer building with healthier employees, consider all the above points of commercial duct cleaning services. Additional savings on energy also help the bottom line.
