Love the heat feature!
on March 24, 2026

[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!

Cool and heat you house all with one unit!
on March 31, 2026

[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.

This unit works well

[This review was collected as part of a promotion.] This AC unit works well and produces minimal noise. The unit is mounted in our living room and it doesnt disrupt our enjoyment of our space at all. The unit is very heavy for me so I had to have my husband install it but he said it was fairly easy. The size is perfect for our large windows too!

[This review was collected as part of a promotion.] Good size & design. Hopefully it keeps both ac’s running and doesn’t break the electric circuit. Summer essential for indoors to survive the heat

Weird plug situation
on April 4, 2026
Posted by: RachelR
[This review was collected as part of a promotion.] The air conditioning and heat on this unit work well. But it wouldn’t replace an entire heating system. Works perfect for us when we use our garage as an added living space though. The major downside is that it requires a specialized outlet which is not easily accessible in most homes.

Great & Powerful AC Unit
on April 7, 2026
Posted by: JamieT
[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!!
