Looking at the old thread where Gerry converted half his garage to a room, I'm considering doing the same. My garage is quite big and I'm thinking of dividing it in half with a wall, using the other side for that "garage" stuff
My greatest concern is how to get heating and cooling in there. I live in So Cal where the climate is pretty consistent, but lately it's been very cold and has kept me from playing. And summer isn't a lot of fun out there either. Is it as simple as routing a vent from the central system?
Who out there has done this? What were the costs?
Thanks for any information.
