As a business, we know how incredibly important it is to keep your company running efficiently by maintaining a productive, safe, and healthful work environment including employee retention. One key factor to maintaining a clean environment is indoor air quality. According to the Environmental Protection Agency (EPA), indoor air is five to seven times more polluted than outdoor air. Poor indoor air quality can impact employee performance as well as increased absenteeism resulting in decreased productivity. The EPA ranks indoor air pollution (also known as sick building syndrome) among the top five environmental risks to public health. Contaminants found in your duct work is a large contributor to poor indoor air quality. To improve the indoor air quality in your work place, start with hiring a National Air Duct Cleaning Association (NADCA) Certified Professional.
Why Air Duct Cleaning?
NADCA is the leader in the industry and sets the standards for professional cleaning. Air Duct Cleaning can have many benefits including:
- Cleaner indoor air quality resulting in a healthier environment

- A more professional image with improved environment
How Often Should the Air Ducts Be Cleaned?
Air Duct Cleaning should be a part of your regular HVAC maintenance schedule to ensure the system is operating at maximum capacity. NADCA recommends air duct cleaning every three to five years; however, the need for air duct cleaning can vary based on setting. For example, food manufacturers, hair salons, dog groomers, and manufacturing facilities that create combustible hazards all require a more frequent cleaning due to the nature of the work. The healthcare industry may also need duct cleaning services on a more frequent basis to help ensure patient safety.
How Long Does it Take to Clean a Commercial System?
The amount of time is really based on the size, scope, and availability of the facility for job completion. Following a proper onsite estimate, we are able to provide man hours in order to complete the job. Things we evaluate during an estimate to determine length of time and price are:
- System size
- System accessibility
- Type of ductwork
- Level of contamination
- Number of crew members required
- Any special equipment needed
The Cleaning Process:
NADCA recommends cleaning the entire HVAC system, including the following components:
- Air ducts
- Air cleaner
- Air filter
- Air plenum
- Drain pan
- Blower motor and assembly
- Heat exchanger
The most effective way to clean air ducts is to employ source removal methods of cleaning. This requires a contractor to place the HVAC system under negative pressure by using a specialized, powerful vacuum. While the vacuum draws air through the system, air charged whips are inserted into the ducts to dislodge dirt and debris that have adhered to interior surfaces. The unstuck dirt and debris travel down the ducts into the vacuum, out of the system and the building while leaving no mess behind.
How to Choose a Company?
Use the following checklist as a guide when selecting an Air Duct Cleaning Professional:
