Commercial air duct cleaning is an often overlooked maintenance task, but it’s essential for the proper functioning of your building’s HVAC system. Over time, contaminants like dust, dirt, mold, and bacteria build up in air ducts, which can lead to several issues:
- Reduced airflow – When ducts are dirty, airflow becomes restricted due to accumulated debris. This causes the HVAC system to work harder and become less efficient.
- Mold and bacteria growth – Moisture can become trapped in ducts, providing an ideal breeding ground for mold and bacteria. This can worsen allergies and respiratory issues for occupants.
- Unpleasant odors – Along with mold and bacteria comes musty or foul smells, which is unpleasant for visitors and employees.
- Contaminant dispersal – The HVAC system can spread dust, dirt, mold, and more throughout the building when the ducts are dirty. This can impact indoor air quality.
- Damage to equipment – Clogged air ducts strain HVAC units and components, shortening their lifespan and leading to expensive repairs or replacement.
The best time to clean commercial air ducts is every 3 to 5 years, though some heavily used buildings may require annual cleaning. The process typically involves:
- Disassembling sections of the HVAC system so ducts can be accessed
- Vacuuming and brushing the interior surfaces with special equipment
- Cleaning any drain pans and blowers
- Applying disinfectants or biocides to kill mold and bacteria
- Reassembling the system
A professional duct cleaning company can determine the specific needs of your commercial HVAC system and perform the cleaning effectively. This service will help extend the life of your expensive HVAC equipment, improve indoor air quality, restore airflow and efficiency, and eliminate odors.
Highlight the health risks – Mention that poor indoor air quality due to dirty ducts poses health risks for occupants like asthma and respiratory infections. Clean ducts can improve employee productivity and reduce sick days.
- Safety measures – A professional duct cleaning company will take appropriate safety measures during the process. This includes plugging vents, covering grates, and using high efficiency particulate air (HEPA) vacuums to contain dust and debris.
- Expect some disruption – Commercial duct cleaning will likely cause some temporary disruption to business as normal. Explain that occupants should expect some dust, noise from equipment, and temporary changes to HVAC operation. The professional cleaners will minimize disruption as much as possible.
- Schedule during slow times – Recommend scheduling duct cleaning during off-peak times if possible, like evenings, weekends or slow seasons. This will minimize the impact on employees and customers.
- Increased energy savings – Mention that clean air ducts allow the HVAC system to run more efficiently, which can result in energy savings of up to 15%.
- Long-term benefits – Emphasize that though commercial duct cleaning is an expense, the benefits to air quality, equipment lifespan and energy savings make it a worthwhile investment for the long-term health and operation of the business.
