Sooooo helpful!!
[This review was collected as part of a promotion.] This AC unit was such a gift to us trying to cool a small upstairs room in the summertime! Note: the plug doesn’t fit a standard outlet so you do need to make sure you have the correct outlet for this machine to function

Heat and air all in one
[This review was collected as part of a promotion.] I have sent in a ticket for this because I haven't had anyone available to install it. I didn't notice how hard it would be getting this window off to put it on and I need help and so I'm trying to get someone over to help but haven't been able to yet. I know these work well because I had one similar to this back years ago.

[This review was collected as part of a promotion.] The keystone window air conditioner was a little difficult to install definitely a two man job to get installed and placed correctly. However the air it blows is definitely sufficient and cools down extremely.

Great
[This review was collected as part of a promotion.] This air conditioner until looks very nice and has worked very well for us. It does weigh a lot but we were able to move it around and pick it up to put in the window. The installation was very easy and it seems to be great!

Great & Powerful AC Unit
[This review was collected as part of a promotion.] This Keystone 8000 BTU 115V window air conditioner with 3500 BTU supplemental heat capacity is a fantastic powerful unit that anyone would be proud to own! It's specifically made for rooms 3505 SQ ft with a window with a Ht 16.5 in & a W 26.8 inches . The adjustable , pleated window mounting kit is included making installation a breeze. It's a very quiet unit with 3 cooling speeds, 3 fan speeds & 1 heat speed. An adjustable 4 way air-flow direction allows you to control the direction of the cool air with 4 way louvers. Electronic controls with LED display allows you to easily select options with the touch of a button. A temp sensing remote allows you to control temp from across the room . A programable 24 hr on/off timer cools on your schedule. In the event of a power outage an auto-restart feature saves your settings for when the power is restored. There is even an easy clean , tilt-out mesh filter with a check filter alert on the unit for easy maintenance . The 7 ft power cord uses the standard 115V electrical outlet. The installation of the unit is easy & took no time at all. The unit produces a great amount of cooling but is not meant to be used as a primary heat source. I was provided the opportunity by Influenster to install & use this air conditioner for free in exchange for an honest review. I can honestly say this Keystone AC unit is a fantastic little unit that provides a tremendous amount of cooling for such a small unit & it is also very quiet . Great AC & a great buy!!

Cool and heat you house all with one unit!
[This review was collected as part of a promotion.] I love how this unit doesn't just cool our house, but it can warm it up too! I frankly never heard of an air conditioner doing that before. It's very nice looking and has every option I can imagine needing on it, including heat and a remote! This is a bit heavy for 1 person to lift by themselves, but not impossible. Attaching the louvers was super easy. Then, we just putting it into our window, closed the sash down and opening the louvers the width of the window. This comes with a manual for installation, use and troubleshooting. The manual appears to cover every necessary subject you can imagine encountering. The front panel opens easily so you can remove the filter for cleaning. The led control panel makes it easy to see what the settings are from a distance as well as in the dark. You can really tell the thermostat on this is very precise when you hear the motor kick up or down a notch, as well as the fan along with it. The remote control makes it easy to operate from a distance. We love the heat option on this right now as it's a bit chilly in the morning. It quickly gives us a little added warmth without turning on the house furnace. We are very pleased this is able cover a good portion of our house. The unit is relatively quiet too, so it won't disturb anyone while they're sleeping either. We are extremely happy with how easy this is to use and all the options it has on it. This has made our home more comfortable no matter what the temperature is outside.

Love the heat feature!
[This review was collected as part of a promotion.] This Keystone air conditioner with supplemental heat has been a great addition to our home. It cools the room relatively fast and keeps it comfortable. The supplemental heat feature is a huge bonus too, it’s perfect for those chilly mornings or evenings so you don’t have to turn on the main heat. Installing it was pretty straight forward and easy. It also comes with a handy remote control, which makes adjusting the settings and temperature super convenient from across the room. It seems to be reliable, efficient, and does what it’s supposed it!

Good unit with both heat and AC
[This review was collected as part of a promotion.] It is a solid unit. Not too heavy. Easy enough to install in window. The best is that it is an AC but in winter can give heating capability. Too cold to turn on AC right now but excited to try the AC part of it

Works really good!
[This review was collected as part of a promotion.] This unit it great for smaller to medium size rooms. It easily cools the room without taking long to cool it. I tried the heat option as well to test it and it works really well too but feel like it takes a little longer to heat up the room. It was easy to set up and easy to figure out how to use it.

It's so great and works so amazing!
[This review was collected as part of a promotion.] Installation was so easy, and it took less than 10 minutes! Seems to be very quiet as well. i can hardly tell it's running unless im in the same room. it's on in. It works so well and cools my entire 900 square foot house! Even on the 89-degree day we just had! I love being able to set the temp, and when it reaches it, it turns off! It's such an amazing unit!

Easy to setup.
[This review was collected as part of a promotion.] This a/c unit was a snap to get installed. It did take two of us, just to take pressure off the window ledge. I ended up putting it in my office about 5ft from my desk. Customers comment how quiet it is, and ask me where to get one. I love that it has a remote. My other ones have not came with one. I am thinking about getting a few more units for the office.
