air duct penetrating garage wall

[Jerry Gilles]

I leave in Florida. Need to condition a room nd the only practical way is to run a duct from the garage wall (separating the living room) to the room in question. I know that that wall is a fire wall and need protection. But can the Florida Mechanical Code allow for a duct to run thru the garage?

Approved material and sealing , Depends on local code enforcement . should be some Fl boys along shortly

[Michael Larson]

As Wayne said or box the duct in and remove all doubt.

Installing a fire damper would be even cheaper.

You would need two.

Thank you, guys. But I am waiting for some input from Florida.

Call a reputable local HVAC company to do the work, and file for permits to make sure you are meeting the applicable local codes and safety requirements. Anything else is basically just a guess at what your local requirements are and the propper way to complete the work.

Of course I do for krist sake. That was an assummed statement that if you have on on the entrance, you have one on the exit.

But one will be lucky to find a 26 gauge duct if at all. I am lucky to find drywall separations up here. Only on new construction do I see it.
I would also like to see a smoke activated damper if that were used anyways.
Doubt if I will ever see one.

I thought you did.

Would it still be cheaper than boxing it in with sheetrock?

I suppose it depends on who does the work.

Considering the duct insulation, the framing, drywall, fire taping. Yes cheaper to have a damper activated by a heat detector since the smoke detector would not work due to car exhaust.

Good info, thanks Marcel.

[Marcel R. Cyr]

Buy one like this for $100

You can get more sofisticated by having one with a heat detector tied in with the rest of the house system, heat detector in garage would activate it.

Hey Marcel , do they still use the heat links anymore?
