Great point. I need to check on that. A builder friend of mine mentioned that most garages lack insulation in the walls. We are having new, high-end, insulated garage doors installed in May. Also just had spray foam insulation put in the attic and knee walls above the garage.
it's still going to get very hot and cold in their
A buddy and I installed a Mr. Cool 12K BTU mini split in my garage and it works great. It took about 2 hours to install.
If the east, west and north facing walls (at minimum) aren't insulated, don't waste the expense on a unit as the results won't be very desirable.
I'll ask this: If all the walls in your house were insulated, do you really need A/C and Heat?
I'm sure there are and they will probably tell you they sweat their asses off playing in the garage, especially in the South.
well noted. thanks for adding perspective.
The garage overhead door is going to be your biggest loss of condidtioned air. The unit would probably be able to keep up with this loss, but the cycle time would shorten and cause the unit to run double time thus shortening the life of the unit. If the walls are not insulated, it is not to bad of a process to have insulation blown into each cavity between the joists. The ceiling is also easily blown as a diy job from equipment rented from the big box hardware stores.
And most importantly, "how do it know?"
I got my table in the garage… it’s only been set up since last fall though. I got through the winter with a space heater. Im not sure how hot it’ll be in there this summer. I live in Charlotte NC.
