Is Venting A Garage of Hot Air Effective
First off, I am posting an odd question here because I have no idea where else to place it, so please forgive me.
We live in a 2-story that has the infamous bedroom over the garage that can never quit get comfortable in the summer and winter. In the winter we fire up a little space heater when necessary and it woks fine. In the summer, it is a different story. Our home faces south and a metal garage door doesn't help even though it's insulated. I have read online about systems where an exhaust fan is either positioned in the roof (we would be able to do this in our third-car bay where there is no living space above) or high on an exterior wall and a vent for air to move into the garage is positioned low on an opposite exterior wall. The exhaust fan runs off a thermostat. My only concern with a system like this is, how is water kept out?
If anyone knows of a professional in the Kansas City area who does good work in something like this, I am all ears.
I kind of doubt this setup you are thinking about will help. Is the temp in the garage much hotter than outside? Are there combustion appliances in the garage?
This is a good approach if there are no gas burning appliances as mentioned. Insulating would be a better alternative and window tinting. A heat load calc for that room is in order. Being over the garage may be only part of your problem.

A good HVAC tech knows how, an educated HVAC tech knows why!
