First time I've come across these units--

vents with 5" hose thru window , exhaust only !
located in 2nd fl bath of 1.5 srory with can lights in ceiling, unsealed.

All that air going out the window was being replaced thru the can lights with 150* air from under the roof deck- !

In the manual and on the website www.edgestar.com there are no efficiency ratings.
How is this legal to sell ??? I thought all HVAC equipment had to meet standards ?

Thanks for your thoughts

Yup, portable A/C units really don't makes sense. One room gets cool at the expense of hot air leaking in other parts of the house.

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.

I've never seen a a coax hose. I've seen 2 hose systems, but they are rare. If you need cooling for one room get a conventional window unit or a mini-split if you have the cash.

For seniors I have suggested the portable units as they can't manage moving a traditional window unit.  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.

Doesn't surprise me, they are more interested in sales and cooling one room than total energy use. 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.

Well, the first unit I looked at on the vendor's website 

AP14009COM - EdgeStar Server Cool 14,000 BTU Portable Air Conditioner - Silver)

says this: 

"Exhaust Options:

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?

That's the commercial unit--I'm dealing with the AP12000.  Exhaust only.

 

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-----------

The manufacturer cannot provide an EER even if they wanted to. 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.
