A new air conditioner for sale.

Hello. There is a brand new air conditioner for sale, used for one day only, as shown in the invoice photo. Reason for sale: the room is too large and the air conditioner is not suitable for it. The air conditioner has a capacity of 18,000 BTU, both cooling and heating functions. It is brand new and has been used for only one day—the ad was posted the same day it was used. Selling for 900.
