My wife insists the garage should be closed in the summer, because we run the AC inside.
However - when leaving the garage closed, temperatures reach roasting levels better suited for cooking than living. I'm thinking the heat from a closed garage will be at least as detrimental as leaving the garage open.
We live in a new house with properly insulated doors and windows.
Will leaving the door open raise the AC workload - (and thus the bill) ? And if so - is it likely to be a large, medium, or small increase (relatively)?
