Got it out of the box and let it sit upright overnight as recommended. Hooked it up, turned it on. Compressor and fan are working but it is blowing 84 degree air out. Called Customer Service. No help. Taking it back to the store.

Read the fine print!!! The heating unit will not work if the outside temperature is below 41 F. Could have bought something that actually heated and cooled for a lot less.

The difference to the bedroom with this air conditioner running was wonderful.. We could actually sleep at night!!!!!

Decent sized unit. The packaging makes it easy to roll around, really not much assembly required other than connecting the 2 hoses (intake/exhaust) to the back of the unit and to the pieces that go in the window. Double hung setup seems like the...

Unit AC worked fine, but you will need a drain hose. Unit ran 4 hours in non-humid conditions and unit shut off. Drain plug is at bottom of unit and near impossible to reach. You will have to undo the hoses & connections (cheap) to move the unit to...

As a senior adult I have seen much & purchased plenty! This portable fast cooling unit is a real gem! My 58 year old niece installed it for me since I have cancer. It was so easy for her & wow can I enjoy my sunroom finally! Love this cool fresh air!

The window-kit didn't fit my particular window, but that's okay, I had read that it doesn't fit anybody's window really. Also, the air conditioner is unable to cool a 400-square foot room if I have the window so much as cracked. But when it starts...

It does not seem to be that energy efficient-electric bill went up about $70.00 over our last portable ac and it was 3 years old. We used the old one just prior to purchasing this new one and noticed the signifcant difference when our bill arrived....
