  • GREAT AC!
Should've wrote a review long ago. I will make it short. This AC does all it claims to do and it is great! Blows out very cold air and has for over a year or more now! It is so worth the money and even in the extreme southern heat where I live it's GREAT!

  • Awful Customer Service
Keystone customer service is atrocious. The unit came damaged and missing parts (the AC Wings). This made it impossible to install. Customer service was inflexible with the required documents it needed before they would even acknowledge my inquiry. Then once they had the invoice, they refused to replace the missing parts, or even allow me to buy the missing parts! They wouldn’t even tell me what ac wings would be compatible. All they could say was “sorry no manufacturer’s warranty on a used product.” Absolutely infuriating. All I wanted was to know what parts I would need to be able to install my AC. I haven’t tested it yet, but wouldn’t be surprised if the AC doesn’t work. All in all, the customer service for this company is abhorrent. Buyer beware. ... show more

  • works great
It works, fit's and looks great. The screws for the top rail were not matching at all . We had to improvise but managed to get it to fit tight. The air directional louver was also broke on one side. We also managed to improvise and got it to stay in place. It works really great.

  • Good a/c unit
Had to replace a two year old a/c unit because the coils on the outside got plugged up. It sits under a cotton wood tree. After putting this a/c unit in, I would fine screen on the outside to protect the coils that are exposed to the elements.

  • Attention to detail
I haven't been able to use this unit yet it takes a 3 pong funky plug, but outside of that it calls for 4 screws and I was only sent 2 and the bracket holes are much smaller than the holes on the unit.
