A landlord should be able to continue to add the freon to help you stay cool as long as he wants. The only caveat is that if you continue to suffer long delays between his ability to add freon, he may then be violating his contract to provide you a livable condition.
Landlords are not required by law to provide air conditioning, so they are never legally required to turn it on. During cold weather, however, landlords are required to maintain a minimum temperature (68ºF is the usual minimum).
Signing a lease is a binding contract. The landlord can choose to allow you out of it if they wish, but they are not legally required to do so.
No, the lender can not legally penalize the landlord, the borrower, if the landlord chooses to rent to tenants with low credit scores. Consult an attorney for details.
Sure, lots of leases say that. However, it should go both ways - the landlord should be required to give 60 days notice if the want to terminate the tenancy.
Yes, no matter if your lease states it or not, the landlord can legally do this if you're behind on rent.
A landlord cannot legally harass you for rent if your rent is not in arrears.
it all depends on the landlord.
Absolutely.
With a legally binding tenancy then no.
Your landlord is not required to provide air-conditioning, per se. But this is probably not the issue here: the issue is, is your landlord required to fix appliances that have been provided, including the air-conditioner? That answer it is: yes. If your air-conditioner was working when you moved into the apartment and it is not working now, then your landlord has the obligation to fix it. If he doesn't and you provide adequate notice, you can have it fixed and take the cost of repair off the rent. The procedure to do this is as follows: at least seven days before the next rent is due your landlord must receive the letter from you stating that the air-conditioner is broken and that you demand that it be fixed. It must also state that you reserve the right to have the air-conditioner fixed and to offset the rent by the amount of the repair. Keep in mind, however, that your landlord can still try to file an eviction against you. If this happens then you need to go to court and fight your case: you will win it likely.
No. The problem was not caused by the landlord.
Depending on what your lease states, they may be able to.
