General Electric 5,050-BTU Mechanical Control Window Air Conditioner, White but its from walmart, brand new is $109, we used for 3 weeks while waiting for our new AC/Gas system to be installed. I use the term loosely because it was only on at bedtime and only a few days where it actually got hot enough to turn it on.
I believe this could cool a living room as well, in a small/normal sized house (our house is 1400sqft, i have faith it could have cooled the main level) but it worked well since we used it in an enclosed room. It wasnt terribly loud.
PICK UP ONLY Hilliard
Basicly brand new. Would like $95
Its a basic AC, no frills. Worked REALLY well for our needs. Great for if you only need to cool a small area like a bedroom.
