I don't know of any state whose statutes require A/C.
If the AC is part of the rental agreement and is not excluded from that agreement YES
Landlord needs to fix it unless tenant damaged it. If the Landlord doesn't fix it call Code Enforcement.
If the air conditioner came with the apartment, then No, the tenant is not responsible. It is up to the Landlord to fix it. I know this because I am a landlord myself. If the Landlord refuses to do so, call a repairman, get it fixed, get a copy of the bill and deduct t from your rent...however make sure you let the landlord know that you will be doing this if he still refuses to fix it and again, make sure you give him a copy of the bill when you pay your rent.
==Who's AC is it?== I think so, if it's not yours. If the AC unit was there when you moved in -- IOW, if the landlord provided it -- then you should send him the bill for the repair. Of course, he might have wanted an opportunity to use his own guy to do the repair and give you a hard time about it.
I call an AC engineer.
Yes, you can break your lease if your landlord refuses to fix things, as long as this is specified in the lease. Your landlord is liable for keeping the home in working order and safe. Contact an attorney to help you with the lease.

Yes i'm sure someone can fix an AC. Try a phone book smart stuff.
The three day notice is also called "Fix or Quit". Which means in 72 hours you need to fix the breach, or quit the lease. If you pay the rent and the landlord accepts it, your leasehold continues. If you attempt to pay the rent and the landlord refuses it, keep a record of the date, time, and place (you may even wish to bring a witness with you). Refusing the rent, shows the landlord did not follow through properly on the 3 day notice to fix or quit. You chose the option to fix the breach but the landlord rejected it. While this may not fix the eviction, it will look better for you in housing court.
The landlord is responsible for anything needing done to make the property suitable for decent living. AC and heat, hot water, roof leaks, good plumbing ect. are all on the landlord.
If you damaged the drywall, then you should fix it. If the damage was caused due to a water leak or something that is unforeseen at the time a rental agreement was formed, then the landlord should repair the damages.
It depends on your lease agreement.
Sure. He just has to fix them before he rents it.
