Hypothetical question

I've been trying to resolve this on my own but I'm stuck.

landlord won't fix broken heating. I've been dealing with this for about 2 months now and the situation isn't improving.

I have been renting for 5 years. My monthly rent is $3,353. I have a written lease.

Am I overthinking this or is this a real legal issue worth pursuing?

Illustrative response

This is exactly why I started documenting everything from day one.

Have you checked with a local real estate attorney? State laws vary a lot on this.
