Need some advice. I am building a small 2-channel room in my garage (my man cave). It is a 1-car garage that is also shared with a laundry room so space will be tight. The final inner dimensions are going to be somewhere around 10’ x 9’ with a 6.5- 7’ ceiling. Not an ideal space but it is all I have.
Living in FL, humidity is high so this room will have to be constantly under climate control. The room will be built with double sheetrock, staggered studs and completely isolated from the existing garage walls or ceiling. A rubber industrial mat was used under the room frame.
I am struggling with the climate control part of the room. I have a central air system in my house and I ruled out hooking this room up to it mainly because it will be a nightmare running a/c and return vents into the room the way it is situated, and doing so will allow the sound to travel the whole house.
My only option is a portable A/C unit with the exhaust vent running out the front of the room towards the main garage door. This room will have no windows and 2 industrial weather-stripped doors as the only access. My question is – would 12”-18” of space between the room and the garage door be sufficient for the exhaust to effectively remove the hot air from the room. This 12”-18” of space would be the only non-air conditioned space left in the garage for the exhaust to go. The only other option I see is to try to run the exhaust under the main garage door to the outside, or punch a hole in the door or wall.
Can anyone think of other options? Sound proofing and A/C is a pain. Thanks,
