Ductwork rattling or popping? Here's Who to Call
Rattling, popping, or booming sounds from HVAC ductwork are usually caused by thin sheet metal expanding and contracting as heated or cooled air passes through. While not always dangerous, the noise can indicate undersized ducts, loose connections, a clogged filter creating excessive pressure, or poor duct support. An HVAC technician can identify the cause, reinforce or resize problem sections, and seal joints to eliminate noise and improve efficiency.
