Choates HVAC and the National Air Duct Cleaners Association (NADCA) both recommend cleaning air ducts every three to five years to keep dust, dirt and debris at bay and improve indoor air quality. However, in some environments, such as food manufacturing or combustible dust production, more frequent cleaning may be necessary. While it is possible to clean air ducts at home, it is often not as thorough as a professional service and can even damage the ducts or the air conditioning system. To keep them in good shape between services, follow HVAC duct cleaning recommendations, such as changing the filter every 3 months.
When deciding how often to clean your duct systems, consider factors such as visible mold, signs of pests, or excessive dust or dirt in the rooms. Professional air duct cleaning usually involves the use of blowers, vacuums, and specialized brushes to clean the supply, intake and return ducts throughout the house. It usually takes 2 to 4 hours for a professional service to complete the job. If you notice musty smells when you turn on the oven or see signs of rodents or insects in the HVAC system, it is best to call a professional right away.
Professional air duct cleaning companies are experienced in identifying and eliminating mold infestations and other issues that can affect air quality. Minimizing machine downtime and maintaining a clean and safe environment for your employees with an air conditioning cleaning partner backed by a history of hard work, integrity and a commitment to excellent service can help keep air ducts cleaner and reduce the need for frequent professional cleaning. Keeping a home clean, changing HVAC filters regularly, scheduling annual HVAC maintenance, and addressing humidity issues promptly are all important steps to take.
