Your landlord cannot increase your unit during a tenancy. So if you have a one year lease, and repairs need to be made (based on needed repairs that did not occur because of you), your landlord will need to make repairs but cannot charge you for them. If you are still in an enforceable active lease, you need to inform your landlord that he cannot increase your rent during your lease term. Keep in mind, read your lease carefully. If your lease allows you to automatically renew your lease (giving you the option) and the landlord has to accept it, then make sure you can renew at the same rental price. Otherwise, think about the following. If you don't have such a lease provision, and your landlord must keep the rent the same until the lease expires, you may be forced to move after your lease ends.
