Hi Team, I recently came across, for the 1st time, 2 Supply registers from the furnace on the back wall of a garage. I questioned if the current homeowner put these in and the realtor said that he did so cause he works out in the garage and wanted some conditioned air.
I feel that this is an issue cause any fumes can be drawn back into the system through convection.
What are your thoughts and thanks?
