Air Ducts / HVAC Systems

Did you know?

Commercial air ducts are a collection source of contaminants that may affect health, such as mold, fungi, bacteria, viruses, skin scales, pollen, rodent feces, insects, and microscopic dust particles.

Why clean it?

Cleaning of the total ventilation system will increase the facility’s indoor air quality (IAQ) and reduce potential health risks within the building.  These health hazards can result in allergies, asthma, illnesses, fatigue, eye irritation, diseases, and sinus congestion, to name a few, which will decrease your employees’ productivity.  

Commercial systems that have dirt/debris inside have to work much harder than a clean system.  A clean system will run much more efficiently which will result in lower energy costs. In particular:

  • Dirt buildup on coils provides unwanted insulation, making the system use more energy to transfer heat or cooling. Dirty coils also restrict air flow, making the fan work harder.
  • Dirty fans use more energy to operate, and are at risk of becoming unbalanced and/or wearing out more quickly.
  • Clogged ducts or other system components make the system work harder to deliver the desired amount of air flow.

How often?  NADCA Standards

Industry standards recommend that you have your air ducts inspected every 2 years (annually in hospitals) for contamination.  Cleaning is unlikely to be necessary at those intervals unless there has been some recent construction or renovation, or some sort of problem, but inspection is important. However, a regular annual cleaning of coils may be a good idea in order to maintain the operating efficiency of the system. Based on research conducted by the American Society of Heating, Refrigeration & Air Conditioning Engineers, (ASHRAE), you can save from 10 to 25% of the average operation cost for up to 15 years of service life on your A/C unit, or from 25 to 55% after 15 years of operation by maintaining coil cleanliness and efficient air cleaners.

What do we clean?

Airways can clean any or all of the many parts of a commercial ventilation system. This can include the interior surfaces of the commercial supply, return, or exhaust ductwork, the air handling units, the coils, fans, grills, registers, diffusers, and other system components.
