Air quality, both outside and inside, has become a big concern for lots of folks. Smog and pollution levels are now reported at different times of the day just the same as temperatures and humidity are. Much of the air quality is due to man made factors such as cars and factories and much is due to environmental factors such as dust and pollen. One person can’t do much to change the quality of the air outside but they can have an effect on the quality of air in their home.

The whole duct system should be cleaned, not just the easy to reach areas. The mechanical parts of your system (the fans, housing, coils, etc.) should be cleaned too. Any component of a system can become dirty or contaminated. All parts should be cleaned simultaneously because a part that was not cleaned can re-contaminate the clean components. Be particularly doubting of air duct cleaning companies that advertise “specials” that seem particularly cheap because this may indicate that they intend to clean only the ducts and registers, not the complete system.
If you get your air ducts cleaned be sure to hire a qualified contractor because an unqualified contractor can do more harm than good.
