Cooling garage
My central heat unit is in my garage. In the summer.the blower and A coil sweat.Would it be best to install a window unit or add another duct from my plenum? If is the latter,would I need a return vent as well? It is a one car garage with a ten foot ceiling.Thanks for the help.

Welcome to the forums.
If it's an active and used garage....... you cannot add any duct work from the air handler. That would be a possible CO issue. If you want to cool the garage..... you'll need to add a separate unit.

Why would the AC coil be in the garage?
Was it an open carport that was later enclosed?

Used to thinking about the flat evaporator coils in my office.

It is common practice in commercial settings when an air handler and duct work and cold water lines as well are in a non-conditioned space that it is all insulated.
Foil faced fiberglass can be wrapped around all ducting and the air handler to eliminate your problem.

Thanks for the good info.So far,I have insulation on the A coil box and plenum and I will add it to the rest of the unit.Wouldn't a window unit do the as a dehumidifier? I have also thought about enclosing the whole thing with studs and sheetrock but don't know if that would solve the sweat problem.

The proper way would be to insulate anything that is not in the conditioned space and/or sweating.
Of course you could install an air conditioner or even try a dehumidifier but it seems ridiculous to turn an unconditioned space in to a conditioned space because of a sweating pipe or duct!
You just need to wrap your head around the idea because it is a commercial type solution for a residential problem
You just need to research foil faced fibreglass insulation then go do it.

Just noticed you mentioned
This will make the problem worse because you will still get condensation only it will be hidden.
