Is the garage attached, and below the house, under ground level (mostly?). If so, it shouldn't freeze. I keep my kegerator in an an attached garage that's at ground level, and we have sustained near zero temperatures here (days at a time). It's never made my beer colder than the 36 I normally serve it at. You would have the lines going from the fridge to the bar insulated.

Sometimes when I reflect back on all the beer I drink I feel ashamed.
Then I look into the glass and think about the workers in the brewery
and all of their hopes and dreams. If I didn't drink this beer, they might
be out of work and their dreams would be shattered. Then I say to myself,
"It is better that I drink this beer and let their dreams come true than
be selfish and worry about my liver."
