    Default Furnace in garage

    This furnace is in the garage. The return air registers are in the house. Any recommendations?

    Thanks,

    Ryan

    Well, the duct work is metal, required to be 26 gage.

    Is that an uninsulated duct going up to the right?

    It is not permissible to screw and support the vent and conduit to that metal duct.

    Insulation, what is left of it, has the facing exposed and should be covered and protected with drywall.

    Gunnar, no I am not asking you to do my job. Maybe I should have been more specific and asked are furnaces allowed to be in garages and exposed like this? This is the actual garage that the furnace is sitting in.

    Yes, but all the duct connections and connections to the air handler need to be sealed (tape, mastic, or other approved sealant applied in the approved manner).

    Ryan,

    Sorry, that came out more harsh than I intended.

    Don't forget vehicle protection (bollard).

    Can the plenum support the weight of a furnace? I generally see them supported on a wood framed platform with the plenum located under the platform. Guess you don't have earthquakes there.

    On an unrelated note, I see a duct running up through the ceiling. Is that living space above without a separation wall?

    This always makes me laugh when it comes up. It must be a regional thing.... 95% of new construction in my area has the furnaces in the garage. As JP said, the duct penetrations must be 26 gauge. Check fire sealant/taping around vents, ducts and other penetrations to maintain fire separation (gaps around the back of the plenums is a common problem). And, as Gunnar mentioned, vehicle protection.

    Those are the main things that come to mind.

    What about the exposed vent. Just a thought.

    I would be concerned with the lack of a combustion air pipe as storage of chemicals is present in most garages.
