We have a cement wall between basement and garage with 2by8 and a wall on 1st floor on those boards. Can we put a heat duct through to garage which is now a room?
I really don't see why not from your brief description. It depends on a few factors. The size of the room you wish to heat and the location and output of your present furnace will determine the size and location of the duct you require. Most good Heating Co. can determine this for you. If a small say 2' section of unsupported wall must come out , then this area may have to be supported by a small lintel/ beam ( supporting the floor above.) Get a few Estimates.
Do your homework.
This is possible, I would decide how much you are willing to invest to have this duct go through the room. Then I would contact a company with the required skills to do this. But I would decide on the company based on passed client reviews online or by talking to some of the clients in person to allow you to decide if this is some you would like to serve you in your home.
Thank you,
