I have been very disappointed with this air conditioner. The fan function is not working properly…it blows the same at each level, no matter if it's high or low. It doesn't cool well either. Currently the temperature outside is 75 degrees and my inside temperature is 80…and I have it set at the lowest cool temperature, which is 61. It will not cool down to that temperature until around 2 or 3 am. By the way, my house is 336 square feet, so there should be no problem for that. I was hoping for better for that kind of money. That's a hit my income couldn't afford, and to have it no cool/blow properly is heartbreaking and extremely disappointing.
