Permalink Reply by Bud Poll on July 31, 2012 at 3:05pm I thought some of the portable units used a coaxial vent so they could pull in outside air and then vent the heat right back out. I looked up the unit mentioned and was surprised to see no such description.
Thanks for the heads up Ken as I will be sure to avoid this in my future suggestions.

The portables use a simpler window panel which allows them to move the unit as needed. BUT, I've never installed or used one so I will do a bit more research before I make any more suggestions. Amazing how a mfg can mess up something so simple.

For the cost of one of those portable units you can buy a 5,000BTU window unit for 4 rooms. Then the seniors wouldn't have to worry about moving anything.

says this:
A window vent kit and dual hoses are included, and the AC can be easily installed through the wall or paired with an optional ceiling vent kit."
Doesn't that mean you exhaust the old air out one hose and get the replacement air through another hose?

My greatest concern is that these are sold withour EER's. As no one on this list has dealt with that aspect of my post, I'll take it to LBL
Stay tuned-----------

Without knowing the temperature of the air entering to replace the air exhausted from the condenser there is no way to know what the net BTU output is. I suppose they could use 95F, same as OD temp for standard EER tests.
