Split Air Conditioner

I have two split air conditioners; I don't know if they still work or not. They were working perfectly with me, then I moved and left them disconnected for about 3-4 years, so I haven't tested them. One is small, 12-ton capacity, and the other is larger, 18-ton capacity, weighing one and a half tons. I'm selling them at negotiable price starting from 700. Reason for sale: I moved and couldn't install them in the apartment. Price reached 1000. Please complete the deal if you're serious. If you're not committed, do not negotiate.
