When we moved into our house the cement was very dark, and it really made the room feel a lot smaller. It's hard to find any stains that will make the cement lighter. We ended up just putting down carpet over it.

Hi Karflan, you have received a lot of great information so far. Definitely get the units looked at by a good A/C company (let me know if you need a rec). If they are still functioning correctly, you may just want to provide an allowance in the negotiations.
If you want to help your house stand out from everything else out on the market, you may want to get a pre-listing home inspection. I added a link to how it may benefit you at the bottom.
