How Do I Properly Vent A Portable Air Conditioner In The Attic?
I have a small work room up in attic that is insulated, wired, and completely sealed from the rest of my attic. I bought a portable air conditioner. There are no windows. Should I exhaust the a/c into the rest of the attic or vent it through the roof? Also, what should I use for an intake to bring in fresh air from the outside....just a second vent with a good screen and a fan to draw air in? Any help would be greatly appreciated.
Answer:
Thru the wall or window unit .... would be the proper way to describe a unit. So I am not sure what your are talking about. The type units I mentioned need to be installed just as the names imply. Safety First. You should never vent anything into your attic. It will cause excessive moisture and eventually mold. If you can get the duct work to it somewhere in your soffit would be a good place to place the vent Something like a screened dryer vent should work. A good screened vent is all you need to draw air in. The a/c will pull in all the air it needs with no help needed. Make sure you figure a way to block off the vents during the winter or you will have a cold room. You should vent the hose from the portable air conditioner to the outside.You should do this through a side wall. Place a bird blocker screen over the vent. Also, cut the hole lower than the vent hose so rain won't get in. Yes, 1 more vent hole with a bird blocker screen and a fan would work great...
