Re:FFRS1022R1 Frigidaire 10,000 BTU Window-Mounted Slider / Casement Air Conditioner. 
Purchased the unit in May 2020 to provide supplemental  AC to a house that does not have central AC. Finding a quality unit for a casement window is difficulty, but this AC was the ideal unit a it surpassed all the others in features and quality. The unit was relatively easy to install and heavy, but we added a wood frame  for extra support (see pic). The unit produces continuous cold air with a mighty force. It even feels like we central AC! The control features on the unit and remote are simple in design and easy to understand.  You can set the desired temperature and this unit will come on/off as needed. This AC unit works as advertised and is a excellent product for the cost.
