It's still winter, but I'm prepared for the sweltering summer that hits my workroom each year, thanks to this TCL air conditioner.  Ready out of the box and installed within minutes using the included window expanders and foam seal. While I haven't run it for long since it is still cold here, the air conditioner put out quite a bit of cool air for the time I have run it to test it. For some reason the product did not have a remote in the box as indicated, but no worries because the app was easy to download and makes remote control of the air conditioner simple by phone or through the Google smart speaker. The included accordion expander adds 3"-11" on each side of the window and fit the dormer perfectly in this room. Looking forward to a cool summer!
