Commercial Lease Dispute | landlord won't fix broken heating

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?

This happened to me too. Have you tried filing a complaint with the relevant agency? In my case they investigated and it got resolved without needing a lawyer.

I've dealt with this before.

In my case, it took about 3-6 months to resolve. The key was having everything documented.
