Frigidaire Window Air Conditioner, uses the modern 410A refrigerant, standard 115V power supply, is rated for 12,000 ETU, which is a high output capacity, its Energy Star Rated, so its high efficiency, with minimal power consumption for the output. It’s about 10 years old and it’s been great,. My condo AC wore out about 10years ago and bought this for temporary use until I could replace the condo one. And has worked so well that it hasn’t been a problem. Recently I got a good deal for a new furnace and Air conditioning system so I am no longer needing this unit and it worked to well to see it get recycled. If you want a high output Air Conditioning that is reasonable quiet then come and see this before someone else buys it. Text me for details, thanks
