Your air ducts may need cleaning if you see these signs:

Is cleaning my air ducts really that important?
During normal operation, dust can accumulate in duct work that can lead to microbial growth. Duct cleaning has been shown to reduce this growth, as well as increase the efficiency of your system. In fact, in some cases of extreme buildup, it can increase efficiency as much as 40 percent!
How are air ducts cleaned?
Duct cleaning depends on the extent of buildup in your ducts. A trained technician will inspect each air duct, opening all access panels. If it is determined cleaning is necessary, equipment will be gathered to address your cleaning needs, including brushes and vacuum equipment specifically designed to remove duct work debris. In addition to cleaning supply ducts, return ducts, air vents, and diffusers, your indoor HVAC unit will also undergo necessary cleaning. These thorough cleaning procedures ensure that your unit will run smoothly and efficiently. In all cases of duct cleaning it is also necessary to address the root cause to prevent recurrence including moisture, water, dust, debris, pest contamination, and other pollutants.

Indoor Air Quality
Indoor air quality is one concern that homeowners have when they decide to investigate air duct cleaning. Your heating and cooling system acts as the lungs of your home by taking air in and breathing air out.
During everyday operations in a home we generate a great deal of contaminants and air pollutants such as dander, dust, and chemicals. These are then pulled into the HVAC system and re-circulated 5 to 7 times per day on average. Over time this re-circulation causes a build-up of these contaminants in the duct work.
Most people spend 60 to 90% of their time in indoors according to the American Lung Association. Ducts that have not been properly cleaned and maintained could be contributing to larger health issues by harboring contaminants that could cause serious problems for people with respiratory health conditions, autoimmune disorders, or environmental allergies.
