outrageously high nat'l grid bills

Thanks for all the feedback – I do rent, and I do understand that I signed a lease saying I was responsible for paying heat. But, yes, the lease does obligate the landlord to provide a functioning furnace, central air, whatever and I don’t consider this furnace – a big box that looks like it came from the 1970s – functioning. I keep it on medium to keep my bill down to $230 – but under those circumstances, it’s really only the kitchen that gets heated, and even that room is a little cold (and I don’t think I’ve ever lived somewhere where the landlord picked up heat). If I turned it up, I’m guessing the kitchen would get unbearably warm and the rest of the apartment would still be cold. I don’t know my square footage, it’s a rectangular place divided into three-four small rooms. It’s not big and there are no hallways or doors. I did contact National Grid – they said it’s not an estimate, it’s an actual reading and that my bill did sound high for a one-bedroom. They said most landlords have a service contract with the utility for I guess repairs and cleaning and that if the landlord wanted to have someone come out to look at it, they need to call 1-877-600-4743. So, my landlord is sending their own super to look at it. I’m not confident that will end will. I await springtime.
