I bought this on July 7, 2024 specifically to use in my 2 car garage.  My garage gets quite hot during the day, especially, as expected, after parking a hot car in it.  It takes this unit about 20 to 30 minutes to cool down the garage to the point where it is comfortable to work in.  The only negative is that the remote signal does not travel through objects so I have to use it when standing close to the unit.
