I am considering terminating my apartment lease 6 months into my a year lease. The lease says that I am responsible for rent and damage in case of early termination. My landload failed to provide habitable environment when the air conditioning stopped working in the certain units of the whole building in the middle of the summer. (They took about 2 weeks to fix the problem.) Isn't this considered as bleaching the contract on the landload side, therefore am I responsible for the penalty fees in this case?
