Using air conditioning in the garage might also be too cost prohibitive for your liking. It wants to move. It s a thermodynamic principle that hot air will rise in order to try and escape an enclosed space like your home. Thus hot attic air is moving through this space heating the floor of the room and rendering the insulation useless.

And when it s hot outside they prevent more hot air from entering. There s some attic space above the front half of the garage and two bedrooms over the rear half of the garage both of which get very warm during the summer. Alternatively install passive vents such as gable soffit and ridge vents which are openings in the roof that allow hot air to escape. This can happen in the ceiling areas too with the insulation against the underside of the roof decking but leaving an air gap to the back side of the dry wall of the ceiling of the bonus room.

When it s cold outside these treatments keep more warm air inside the room.

Pedestal fans box fans or even better a higher powered shop fan will get the air in your garage moving. That way hot air in summer and cold air in winter can t enter the room as easily.

Install electric ventilators and attic fans which remove hot air from an attic. The garage attached to my townhome gets the full afternoon sun.
