Keystone 8,000 BTU Window Mounted Inverter Air Conditioner with Supplemental Heat and Remote Control, KSTAW08INV-HC

Exactly the type of unit we were looking for at a modest price! it is in an area that is not used often, but needs to be temperature controlled when in there. we have not yet tried the heating unit but the air works just fine!

[This review was collected as part of a promotion.] This air conditioner is great! It was very easy installation. Everything needed to install came in the box. We have central air but our son's room always stays hot, so we added this to his room, and it made such a big difference! Low level noise, energy efficiency, plus dehumidifier all wrapped up in one with a remote control added on top of it all! Great product

[This review was collected as part of a promotion.] The unit works like charm. My master bed is hotter than the rest of the rooms in the house. This AC definitely helped cool down my 470 square feet room quickly. It runs smoothly and quietly during the operation. It came with everything you need to install. It has a remote control and comes with batteries as well. It is the first time my husband set it up. It took him about 30 minutes to finish the job.

[This review was collected as part of a promotion.] Received the air conditioner and immediately installed. It was packaged very well. It took about 30 minutes to install. I live in the south and this time of year it's warm enough for air conditioning but the nights and mornings are still chilly. As soon as it was installed I turned on the cold air. First, great air flow and super cold air. Second, it is very quiet. I have had window units before and they were very loud. This unit does have supplemental heat. Meaning it's meant to be operated when temperatures outside are between 41 and 75 degrees….it's supplemental and not primary heat source. But, it's perfect for knocking off the chill in the mornings and I could not be happier. The unit also dehumidifies…that is also a plus here in the south! It has a washable filter and comes with a remote. I'm impressed!!

Works great! I love how quiet and efficient it is, would choose this one again.

[This review was collected as part of a promotion.] Positive Review of the Keystone 12,000 BTU Inverter Air Conditioner I am extremely satisfied with the purchase of this 12,000 BTU Keystone air conditioner. From the moment I unpacked it, I could appreciate the quality of the materials and the solidity of its construction, which gives me great confidence in its long-term durability. The ease of installation was a pleasant surprise. The instructions were clear and concise, and I was able to have it up and running in no time without the need for professional help. Once turned on, its optimal performance was immediately evident. It cools the room quickly and evenly, maintaining a comfortable temperature even on the hottest days. But what really impressed me is its energy efficiency. I have noticed a significant difference in my electricity bill compared to my old air conditioner, which is a great benefit for both my wallet and the environment. In short, this Keystone air conditioner offers an exceptional combination of durability, quality, optimal performance, ease of installation, and energy efficiency. I highly recommend it to anyone looking for a reliable and economical cooling solution.

I purchased it for the heater, and it has an issue that I did not understand on real cold nights it will not come on it reads LO until you warm the room up with another source of heat. AC works great.
