My sister has been living in a house for a few years now. She has never signed a lease.The air conditioning has been out for some time. She has purchased window units for the house. She had asked if the price of the units could be taken off the rent and his response was lets wait and see. She has offered to have the air fixed in leu of paying the rent . His response to that was excuses of wedding bills, college, graduation... blah blah blah. It is now almost June and it is hot in southern Bama. Does she have any avenues to exhaust ? She can't afford to move with deposits and such. Thanks for any input!
