I have posted under one name for the last 3+ years. Can you point to one single post was sent by me under a different name?
I don't know Steve @ Carolina Breeze but I have seen enough of his posts over the years to make me trust his knowledge. After being here long enough you learn who to trust on what subjects.
The op said two ton was the smallest sytem available. I pointed him to a 1.5 ton system. I wouldn't have a clue how to answer a load calc question if there was one.
You may have confused me with the OP since we both use the name Steve B. I have no idea whether the OP really has a garage remodel or not. It would be agravating if some people spent this time trying to help him and he was just trying to piss off the hvac guys.
Steve B.
