Product details
At Keystone, we prioritize your family's comfort. Our heat/cool 230V window air conditioner is designed with versatile supplemental heat when outdoor temperatures exceed 23 degrees Fahrenheit. Please note that this mode is meant to complement your primary heat source and should not be relied upon as the sole heat source. It is important to have a special 230-volt/25-amp electrical outlet for optimal operation, as this unit does not function with standard 115V household outlets. Our window air conditioner is equipped with money-saving features such as an energy saver mode, sleep mode, and a programmable 24-hour timer. With the convenience of our Follow Me LCD remote control, everyone can easily adjust settings and enjoy the blissful comfort provided by our unit.

Awesome air conditioner/heat it works great!!!!
[This review was collected as part of a promotion.] I received this product from # Influenster and #Keystone for my honest review. I love this air/heat unit air conditioner! It was easy to install and is perfect for these cold spring mornings for heat then later when it’s hot just switch over to air conditioning. It wasn’t too heavy but did have to have a helper to lift it . It has a remote control which comes in handy. It has 4 way air direction a energy saver feature an auto timer start stop feature it has dry mode to help dehumidify it has fan only setting it is just loaded with options it keeps my house crisp and cool I absolutely love it!!!!

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
