I was going to do a Mr Heater NG in my garage but got all fancy with this Ductless Aire AC/heater mini-split. Cost was more than the
$500 Mr heater being it was $1400 plus a few things like the electrical wire/conduit. It was nice not having to run a vent out the roof or tapping in the gas line. Cooling my garage in the summer was more of a concern to me since it stayed fairly warm in the winter but its an attached 4 car with insulation. Now its 71 in the garage when its almost 100 degrees out. Should do well in the winter too.
