I responded to a call to perform a video inspection of the ductwork beneath the slab of a residential property. Upon examining the ducts, I discovered that a booster fan serving the front section of the home was not functioning, which was likely contributing to the airflow issues. Furthermore, I detected a shift in the duct running towards the rear of the house. Based on these findings, I will prepare a proposal to attempt clearing out the accumulated rock obstructing the ductwork.
