PA landlord tenant law, landlord's responsibility to separate utilities

Another Apartments HVAC Wired To My Electric: Our lease states we are responsible for the gas and electric in the house we are renting. There is an apartment on the first floor with its own gas and electric meters. When looking at the wiring of the HVAC units in the basement I noticed the apartments air handler and outside air conditioner condenser is wired to my electrical panel. I informed the landlord but did not get much of a response. What is my recourse. The utilites are presently in my name. The electric used for the central heat is negligible, but the air coinditioner condenser is a major electrical draw.
