What do I about the fact that the heat doesn't work in my apartment and my landlord is not fixing it?

My lease very explicitly states that water, garbage, and heat are included in my rent. My heat doesn’t work (and according to the building manager – who has been here for 10 years – it has never worked) and I have been promised that it would be fixed but it still has not been. He has come here to “work” on the steam radiators a few times (you know, at like 830pm on a Sunday night) but there hasn’t been a solution that has stuck.

I’m sick of it. It’s effen freezing and I’m never someone who is cold!! I am tired of bringing this up to him only to be lied to. I’m pretty sure that a. this is illegal and b. I am not responsible to pay my rent in full considering I am not receiving the services I am paying for.

Additionally, I have been using my OVEN to heat my apartment. Should I request to be partly reimbursed for my pg+e bill? Not to mention that this is a fire hazard.

I’m angry and I don’t know what rights I have as a tenant. Any suggestions on who I can turn to or what I can do at this point??
