Keep in mind; consider your air system as the lungs of your house. Think about the type of business that you desire to manage your house’s lungs and your indoor air quality within your house. Have the total air system occasionally checked for polluted duct and have it correctly preserved so your Heating and Air System can offer your household with great air quality for many years to come. Certified duct cleaners will follow rigorous requirements set by the National Air Duct Cleaners Association. Enabling an unqualified service provider to clean your ducts could be even worse than not having them cleaned at all. More particles could be separated and launched into your house or your HVAC system could be harmed.
Make sure that the company has the proper equipment and enough HEPA filtered vacuum power (2,000 CFMs or more), to properly clean your air ducts. Be weary of companies that use small vacuum units that have a small rotating brush on the end of a small vacuum hose with a typical airflow of 150 to 300 cfm or less. Proper air duct cleaning vacuums are negative air machines with 2,000 CFMs have 8 inch to 14 inch or larger, vacuum hoses to capture large quantities of dust and debris.
