Question: How long is the electric cord?
Document: I live in Arizona and my garage gets outrageously hot in the summer. I use to have a large fan installed but it was difficult to get enough ventilation to accomodate it. This little ac does a great job of keeping it reasonable in there. Yes, i lose the air when I open and close the door but it manages well in spite of this loss of cooled air. I havent noticed a significant spike in my electric bill.
Also, while 4,000 BTU may be adequate for some, 8,000 BTU reduces energy costs by not having to run constantly (even in power saving mode), when both temps and humidity exceed 90 F or 90%, respectively. I've also noted that the power cord, which has its own built-in circuit breaker, doesn't get hot like the 4,000 BTU's typically do.I did make some changes to the mounting bracket on the bottom, to account for my casement style window.
it is all that i expected! the unit cools a large room and also the stairs and hall way going upstairs. the price together with amazon's discount made a real bargain!
Upon further inspection of the box, down in the styrofoam there it was hiding all wrapped up in blue plastic. I proceeded to take it out and mount it on the top of the unit and immediately there was something wrong. In fact big time wrong. What threw me off was that this metal rail was painted perfectly even though it was all twisted up at the one end like the mighty Hulk grabbed it and twisted it.
This unit cools my second floor bedroom that would otherwise literally be 100 F very nicely but in order to sleep it is pretty much required to have the fan on low. I do have another a/c unit for the living room which is 10,000 btu and it is a little more quiet that this unit. Having said that I would still recommend this unit if you're using it for a small room and you don't mind some noise.
The window mount I also purchased is more than sufficient, and I even recommend getting it for ANY window mount application (three screws, that's it).The unit, as mounted, has thus far withstood severe summer weather (high winds, heavy rain), and performs like no such weather is occurring without any problems.I suggest saving the box and packing materials for winter storage.
The keystone window AC is a very good working air conditioner and I would request for anyone to buy it . !
The AC is not lowering the temperature of any of the rooms but is taking out the humidity which makes it feel cooler. The remote is also fancy, unfortunately, 2 functions on the remote do not work but not the end of the world, the main thing is that the AC works and does what I want it to do. Final note, from the 1st day that I called customer service to the day I actually received the part I needed, it was a total of sixteen days.
So while we were on the phone he took my E mail address and looked through his E mails and found my 2 and opened them up for the first time. He proceeded to make a copy of my receipt and apologized and told me that my order would be processed today and go out tomorrow. But it would still be 3 to 5 days for delivery. And then he told me that that had been flooded with calls and this is their busy season.
Obviously this told me that there was no quality control inspection for this company for this would have never slipped through. I called the 800 # and left a message as the office was closed til Monday morning so I had all weekend to stew. I waited a couple of hours Monday morning and decided to call and get the ball rolling. I talked to an older gentleman that was real friendly, took care of my warranty while on the phone and took me a lot about this company.
