Love the heat feature!

8 days ago
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

24 days ago
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
