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.
Ensuring your air ducts are clean is one of the most simple ways to keep a clean house and healthy body. Since dust and other contaniments pass through your air ducts five to seven times a day, they can contribute to different health problems. You may notice the most common problems include eye and nose irritation, coughing, asthma, and especially allergic reactions. The sooner you have your air ducts cleaned, the sooner you can breathe easy. It’s important to note that when air ducts are being cleaned, all components of the system should be completely inspected and cleaned, including cooling coils, fans, heat exchangers, registers, grilles, diffusers, and air ducts.

On the other hand there are a lot more duct cleaning business that will appropriately clean the air system and duct and make use of industrial damaging duct cleaning vacuums with a minimum of 2,000 CFMs of vacuum power and use correct agitating tools to move the contaminants within the duct to be recorded with HEPA filters and consisted of by the duct cleaning vacuum devices.
