Whirlpool 8,000 BTU 115-Volt Portable Air Conditioner with Heater, White, WHAP13HBWC

Excellent compact relatively quiet machine. Cools well. I predict a long life.

I was very impressed with this portable air conditioner. Once installed, it puts out some really cold air and fast! I did an experiment on a really and humid NC day with the temp at 98 degrees outside (felt like 100 degrees). We keep our air a comfortable 74 degrees and use our ceiling fans in all the rooms to distribute air (blinds are tilted up to reflect UV and heat) and overall, it's very ice. But, I decided to see just how cold and how quickly this air conditioner would cool a 12x14 master bedroom. I closed all the doors off (closet, bathroom, hall door and closed the blinds). Now, here is why I am giving this 4 stars instead of 5. The manual is not very clear as to exactly what tools one would need to make the window attachment fit correctly (ie. it should say: you will need tape measure, saw, a bucket for drainage, and rubber seal strips, etc). I had to cut mine with my miter box saw. Also, the manual shows that there should be rubber seals/strips to fit along the edges of the window attachment to keep from leaking out but there were none. I had to use bubble wrap along the edge for a makeshift seal. And the slide window attachment has a hard time staying in place so you can shut the window down on it before it folds in on you. After several attempts I got it to work. The hose also comes off the window attachment too easily and that took a few trys. However, it took less than 30 minutes at 64 degrees and it was super chilly in that room. I went to another room to see the difference and it was much warmer in the rest of the house. Overall, a good product but needs but instructions and maybe better user friendly.parts. Oh, one more thing...unless you are a power lifter, this thing weighs a ton so use the rollers and get help if you must lift it!
