Occasionally, when servicing a client’s ventilation system, our team finds cables inside the air ducts. This is becoming fairly commonplace since the ducts provide an out-of-sight location for the tendrils of lengthy cords. However, is this a clever hack or can it cause hidden damage?
Air ducts are meant as a conduit for air, not wires. Inserting cables inside the ductwork may even violate building codes.
The reason we don’t advise this is because a technician can damage the cables during an air duct cleaning. This could render your phone line, Internet, and cable television out of service. When we clean ventilation shafts, we use a commercial rotary brush. The brush spins rapidly in a single direction. This can tangle, twist, mangle, and shred the cords, causing serious damage—both to the cables and the rotary brush.
We have also discovered old wires the homeowner was completely oblivious to. The prior homeowner left them behind and they remained undetected for decades.
Air ducts aren’t designed for holding cable wires. While the practice isn’t a major hazard, we suggest keeping the ducts clear of household objects. If you already have cables in the ducts and would rather not touch them, then we can often work around them. For public facilities, we strongly discourage this practice; you can land in hot water if an auditor finds them during a building code inspection. This could also be a breach of the contract agreement if you’re a tenant living in an apartment complex.
We recommend booking a furnace and dryer vent cleaning as part of a whole HVAC inspection. This covers the essential areas of your home. Aurora Edmunds Furnace Cleaning doesn’t advise running cables inside air ducts, though we can work around it if need be.
