Can you run PEX next to ductwork?
I can’t imagine the ducts get too hot, but if I had to keep that minimum distance then it would require me to run the lines through my partition walls instead of the floor (basement ceiling) joists. Any help or ideas would be greatly appreciated! You’ll be safe running the pex right against the duct if need be.
Can I use PVC for heat duct?
In homes, PVC ductwork can allow a heating and cooling system to run beneath the house without being corroded by moisture or even radon. While metal ductwork is generally fine for smaller buildings, PVC is often preferred in larger buildings, where heat and cool air need to travel farther through the ducts.
Can you run PEX through a cold air return?
It’s perfectly acceptable to run pipes and wires through cold air returns here.
Can you run cat5 cable through air ducts?
Quality Cat 5 and Cat 6 cable can easily withstand the higher temperatures in a heating duct (up to ~150 degrees F). But for a commercial installation where you’re running it in the ceiling space between floors, you’ll specifically need plenum cable that is specially rated and code-conformant for this usage.

What’s the problem with running cables through ducts?
The problem with running cables through ducts has NOTHING to do with the longevity of the cable. A cable that is run through areas where forced air flow is supposed to occur (heating, cooling or return ducts, and some raised floors and drop ceilings) MUST BY LAW (in the US) be ‘Plenum Rated’.
