Trouble with tenant during repair

[Jared Tillery]

I had an AC clog causing a water leak in the ceiling. The area has been demo'd and water mitigation is running dryers. The unit is able to get Dow to 75 degrees with the AC running. I have already given her $250 off her rent for the month, said will work with her to cover the extra costs of utilizes. She is claiming her dogs have asbestos poisoning and the unit is to stressful to live in. (Tests for asbestos came back negative) My insurance and water mitigation disagree. She has renters insurance but they said they won't cover it. She says she is going contact an attorney. She posted signs on her door saying no one may enter without giving her notice which I have already told her daily repairs are needed and we will give her as much notice as possible to when they will show up. Her father tried to call and have the dryers removed prematurely. The dryers are a little noisy and large but do not prevent anything. I need some help. I have lost all patience with the tenant. If I need to do repairs do I have the right to enter as I need? What can I do to make her cooperate and quit harassing my wife and me?
