Keeping air ducts clean and clear is important in maintaining the air quality in your home. When dust accumulates in your ventilation system, trouble will occur. Some issues are highly visible, for example, the accumulation of excess dust on the furniture and fixtures in your home. Some issues, however, are less tangible. For example, when you or someone in your family experiences allergies that are worse than usual, it could be related to the air quality in your home, and thus,possibly to your ductwork. Replacing and repairing your duct system may solve your problem, but can be a costly and invasive process. Effectively cleaning your ducts may also have a positive effect, and at a much lower cost. If you know the type of ductwork you have and the problem that is affecting your system, you’ll know whether to replace the system or simply schedule an appointment to have it professionally cleaned.
