Hypothetical question

I'm dealing with a situation in Maryland and need some guidance.

landlord won't fix broken heating. I've been dealing with this for about 3 weeks now and the situation isn't improving.

I have been in this property for 5 years. My monthly rent is $4,242. I have a written lease.

What are the risks if I pursue this? What's the likely timeline?

Illustrative response

NAL, but from what I've read, you should document everything. Every situation is different so YMMV.
