The air ducts in your HVAC system facilitate the movement of cool and warm air around your home. As one of the most important parts of your HVAC system, you must conduct proper duct cleaning as part of your HVAC system maintenance to keep it working optimally. This is because the efficiency of your HVAC is tied to the ducts’ ability to intake and output air for distribution. Although you may clean your air ducts in an on-need basis, you should do it professionally instead of attempting to do it alone.
