Cold Air Return in the Garage

My house has 3 levels with the garage and Finished basement sharing the lowest level. The Cold Air Return metal duct is fully exposed from floor to ceiling in the garage... from there it goes through the wall where it connects to the furnace (inside the house).

Someone told me it is a bad design to have the return air flow through an unconditioned space and that I should try to close in that area with drywall and insulation.

Is this worth the effort? For these metal ducts is is better to try and wrap them in insulation or frame in the space with 2x4, plywood, and insulation?

Thank you in advance for your assistance.

Mike

Cost wise--- Id say just get some ductboard we make duct out of. Cut to fit and glue it to the outside of that cold air drop you have. If there is no heat in the garage for sure put insulation on it.

Make sure it is well sealed as you would not want carbon monoxide pulled into the air system from the garage.
