An indoor air quality problem?

If you can answer "yes" to any of these questions, it usually suggests that your air ducts should be inspected for possible cleaning.

• Do you have "dust trails" or discoloration coming out of your air duct registers?
• Do you experience headaches, nausea, burning sensations in the nose, throat or eyes when inside the home?
• Do you regularly clean excess dust accumulations from your household furniture?
• Does anyone in your house suffer from allergies, asthma, or respiratory problems?
• Do you have pets?
• Are there smokers in the home?
• When you last changed your furnace filter, did you see dust and dirt inside the filter housing?
• Do you notice a dark area or discoloration at the edges of your carpet by the base molding?
