[NSRCA-discussion] Air Conditioned Shop

[Keith Hoard]

"When you are a man, the world is your urinal." - Unknown 

I have a roll-around air conditioner, it works but a 240V Window unit will serve you better. This is from a good flying buddy who owns an HVAC company. 

The roll-around units use air from inside your garage to blow over the coils to cool the freon, which is then vented outside. This creates a vacuum inside your garage which is relieved by sucking in hot, humid air from the outside which now has to be cooled and dehumidified by the roll-around.  When you turn on the unit, you can see and hear your garage doors moving due to the vacuum. 

Yes, this system works, but a window unit which uses outside air to cool the coil$ and keep$ your cool dry air in$ide the garage i$ more efficient.  Al$o, if you can get 240VAC to run that big motor, you'll $ave $ome money in the long run. 

Luckily I have two windows in my garage for the vent tube, but plan on installing a window unit.

Seriously, I have rolling steel cabinets, heat, refrigerator, Stereo, TV, Roku, padded flooring etc; but, no urinal. I haven't told about the A/C yet. I'm thinking this is one of those "Beg Forgiveness instead of asking permission" types of things.

I cut between two wall studs and ran it behind the dryer and up to the window.  It is probably less than 7' total hose length.  Then, I sealed the hole with the tube sticking through it with spray-in foam and everything worked well.  I considered cutting through the brick and making a nice exit but that hurt my brain.  I'm a computer guy not an architect Jim!

After looking at different possibilities, I wound up cutting a hole for the tube and exhausting it out the laundry room window as designed.  It worked perfect and cools down the 22' deep garage  from regular closed garage temperatures in Southeast Texas (read freakin hot and humid) to 75-78 in a few hours.
