My home came with the garage vent fan already installed when I bought it. All it seemed to do was suck in the hot humid air from the outside. That is not comfortable at all if you want to work in your garage.
Better option for me was to insulate the garage attic and install a 24,000 btu Mitsubishi mini split. It was a 20.5 seer high efficiency unit. It is sooo nice to have a cool temp and low humidity in the garage. That is really a much better solution if you intend to use your garage as I do. I am doing some brake work on my classic car today in the garage. I wouldn't even consider it with the previous vent fan set up I had. Too Hot!!!!
I doubt it is any more expensive to run the mini split than the garage vent fan, but much better comfort level with the mini split.
