Keystone12,000 BTU Window-Wall Air Conditioner with 11,000 BTU Supplemental Heating and Dehumidification, 230V, Window and Wall AC Unit for Living Room, Apartment, Medium Sized Rooms up to 550 Sq.Ft.

Replaced ancient unit in small Florida home. Works as advertised to cool nicely & warm home! Works great! Thanks 👍

We are using this for a guest room that doesn't get heat or air from our main unit in the house This is perfect as the our guest can regulate the temperature to their liking, and the noise level is low so they get a good night's rest.

I ordered this unit quite a while ago. It’s been sitting in the box until I could have someone install it. It is heavy and I am disabled. First of the bottom side of box was broken. Didn’t look like it affected anything. I was present the whole time it was opened and installed. The right side of the instrument panel was broken just a clip. He said it shouldn’t affect anything so I went ahead with it but when I went to clean the filter, the whole instrument panel is not connected to the unit. Therefore it wants to fall out when you open to clean your filter. it looks as if two screws were not attached to it. I am 58 and disabled. I do not know about such things and because the person that I had install it never looked at it we had no idea! As far as working? The unit doesn’t get very warm it Has to be set almost at 75 in order just to feel any warms in a very small area about 450 ft.² to be exact? Then it doesn’t want to shut off once it starts running. I have to shut it off and on through the remote? Overall paid over $500 for this unit it is installed. I cannot do anything with it but I do want to warn people it is not as they say, and I’m very very upset with this purchase I’m afraid to see what it’s going to do when the weather turns warm will it work as an air conditioner? Or is it just gonna blow air? Very, very dissatisfied

keeps my small house pretty toasty. when in heater auto mode....when it's about to shut off it goes into almost an AC mode? i guess it needs to cool down before shut off. But, it doesn't seem affect to overall warmth in the long run.Nice unit, & the heater actually works. I bought an 8000 BTU unit for my bed room....but heater NEVER seemed to get warm?? It was like a fan blowing.

If your perimenopausal you'll love this AC.Keep my room extra cold.

We bought this unit to replace the existing ac only unit in our house addition. It was fairly easy to install. We did have to replace the plug receptacle to accomodate the plug. Not a big deal, though. Overall, extremely happy with the purchase. The unit is easy to operate. It came with a remote,which is a bonus,because the description said there wasn't one. the air is nice and cold and is sufficient for the 2 bedrooms and bathroom that it serves. Terrific for summer in Southern Mississippi. The unit is a little on the louder side, but not obnoxiusly noisy. I haven't tried the heat yet, but for the price, that option was a bonus.

Just got the 18K model and installed it. I did some things to secure it without drilling into my vinyl window (as they direct), but made it secure. It blows cold air as expected, yet not had a great heat wave yet to really put it to the test.My one gripe is before purchase I ask in Q&A “Is the heat function via heat pump?” which I wanted for the energy saving benefit (having other heating when needed for freezing temps that others ask about). I got “Yes it is heat pump” and the product details of “Supplemental heating when temps out are above 45” hinted such as well (I have used portable AC units with heating that depend on outside temps being above freezing). Yet when sliding out the main assembly from the “sleeve” frame for mounting, I instantly noted a rough wire diagram with heating elements shown that connect directly to 240V power via relay contacts. I unplugged one of those wires to disable the elements and see if it did ANYTHING without them for heating, but it doesn’t (besides blow air with the fan going). So this (like most others with the heating function) gets heat ONLY from heating elements (NO HEAT PUMP feature). Some may think “It’s not their fault you expected something it doesn’t have”, but I did my homework, tried to ask (where they failed to respond), and I don’t understand the advertising “…heating when temps above 45 outside…” statement when outside temps don’t matter with heating elements. So that’s why they lost rating with me (making me decide to return it and get one with the features I wanted). I'm sorry for the hassle to Amazon etc, but hope they'll edit the product details to not hint features it doesn't have.

My central a/c was not cooling adequately, within 30 minutes, the room was cool, I no longer use the central unit. It's quiet, thermostat works perfectly.
