Old Home in Crystal Lake Gets HVAC System Restored

Wall cavity air return beforeWall cavity air return afterOld homes can be charming but they can also hold remnants of previous homeowners. Most homes today are built with metal cold air returns that feed the air back to the HVAC unit via duct work, this home was built with wall cavity air returns. This allows for potential contamination throughout the home and could be damaging to the HVAC unit. We were quite surprised when we opened up the air return and unveiled over 40lbs of construction debris and insulation.
