Any recommendations for a portable A/C, about 8000 BTU (the kind with a
flexible duct that goes into the window)? I don't need heat from it -- just A/C and dehumidification. The names Soleus and Amcor pop up a lot. The familiar names like Friedrick don't seem to have anything at all. -- Reply in group, but if emailing add another zero, and remove the last word. |

PC Richards carries Amana, and occasionally another brand.
I have two. So far so good. About $350. Newspaper ads show others, about the same price. But even the salesguy was hemming and hawing, as they supposedly get a lot of returns, due to high expectations. The EER is very low, the BTUs proly not what the label says (about 8K), but, for excellent dehumidification (buckets of water, also will throw the condensate out with the heat (a misting process--nice), which might even help efficiency), and passable A/C, if the space is not too big, or enclosed, like a basement. For winter, get a standalone dehumidifer--which also acts as a 600-800 watt heater. -- ------ Mr. P.V.'d (formerly Droll Troll), Yonkers, NY Stop Corruption in Congress & Send the Ultimate Message: Absolutely Vote, but NOT for a Democrat or a Republican.

A dehumidifier would remove humidity, and add the full heat load initially. After the dehumidifier ran for a while, wouldn't the sensible heat be lower? R |

The names Soleus and Amcor pop up a lot. The familiar names like Friedrick don't seem to have anything at all. Don't waste your money on one. I had an 8000 BTU model. It was a worthless piece of junk. They have a *very* serious design flaw - the air the gets blown across the condensing coils (high side, the hot part) on normal a/c units comes from outside, blows across the high side, and is vented to the outside. Works great. With the portable units, the air that blows across the condensing coils comes from the room your are trying to cool, and is vented to the outside. This causes a relatively high volume of air to be vented to the outside - and hot air to be sucked into the room. IOW, it is constantly sucking in a lot of hot air from outside, and trying to cool it along with the hot air that is already in the room. Because of this, they will not cool as much space as a window mount 8000 BTU unit will. Bite the bullet and get a window mount unit. |

your far better off buying several window units, more efficent, no
moving hassles, quieter, since at least some of the noise is outside. and small window units are cheap. |

My 2 cents on a portable AC: 1) Get a model with two hoses - the two hose models use outside air to cool the condenser and will be more effecient. You will not be sucking the cooled air out of the room to blow it outside - this is what the models with one hose do (the condenser air comes from somewhere. 2) Be prepared to have a real drain (ie hose going somewhere) on the unit unless you want to be emptying condensate all the time. They seem to be able to blow some condensate out the air hose, but unless you are in a dry area you will probably get more condensate than what it can evaporate out the air hose. (If you want to pump water out the window you will probably need a condensate pump and some 3) They are for the most part pretty quiet. It seems most of the noise is what you can hear through the thin walls of the air hoses leading to the window (these hoses connect to the area the condenser fan and compressor live in - most of the noise is in there).
