Having a portable Ac is so efficient, it can help cool off your home with out the need of a window unit. 
It definitely is. It also helps flush out the heat and cool down a room very quickly, which I appreciate.
And when they get to the temperature of choice they have an Auto shut off, which is so cool.
Yeah, it helps conserve electricity! I think that's a really neat feature.
Is yours the one where you have to add water and ice and keep an eye on the level indicator light or it doesn't need anything added?
Nope, I don't have to add anything. I'd be pretty frustrated if I had to add water and ice every once in a while.
Yes it would be very tedious to add water and ice constantly. Do you only need one for the whole house or need multiple ones?
I have a larger AC that's supposed to be for the whole house, but I've got this smaller portable one just for my room.
Oh well that is amazing that is can cool down so much. And yes a cold room is a must.
For sure. I can't work in hot environments.
