Should I change ceiling fans for my tenant?

[A.J. Simmons]

My tenant wants to take down one of the ceiling fans that was in place when she moved in. I don't mind because the fan was missing a blade, so she'd be doing me a favor. She asked if I could remove the old one for her, so she wouldn't have to pay someone for removal and installation. I tried and failed. Should I let her pay for removal and install, go half on the cost with her, or get back in there and figure it out myself? We have a good relationship. She helps me, I help her. She's never been late on rent. Am I going too far by considering to help (since it was her idea and it's not a critical issue? Or am I just being a good landlord? After all, it should've been fixed before she moved in.
