Today we visited to determine why the home gets so much dust. We learned the ductwork should be replaced. There are three styles of ductwork in the home. The trunklines are fiberboard, the individual runs are metal, and there is flex duct from the air handler to the trunklines. The fiberboard ductwork is leaking in several places and when touched shows clear degradation. A few of the supply vents have mold/mildew growth with the vents closest to the air handler being worse. I let Paul know the complete replacement will cost roughly $12-$15k. He will give us a call back when he decides to address the ductwork because he’s considering selling the home. When Paul calls back we can arrange for James to visit and complete the home drawing to provide the exact cost of the installation.
