Air conditioner and heater 240 volt

I bought this unit at the Folsom flea market in May 2023 with plans of installing it in my garage. Now I decided to wait and save up till next year and get a mini split. This needs a 240v outlet to run this AC .any issues bring it back I'll give you a refund but I was assured by the vendor that I have known for years that is working air condition. This is a good size AC and it should be able to cool down a living room. I can't find the model number on this unit but I found one on home Depot that's very close to the dimensions of mine. It should be at vey least 12,000 btu here are the dimensions again 26"X 22" X15
