Can I keep an AC I buy for a rental?

I'm moving to a rental house soon with no aircon. Checked with the agency and they say its ok for me to install my own air conditioner. My question is, when I decide to leave, is the AC just a lost purchase, do they reimburse me a part of its cost, or is it cost-effective to pay for it to be uninstalled and reinstalled somewhere else?

Thanks.
