I have a central ac unit system. The cooling works but the heater doesn't run.
I have a central ac unit system in an apartment. Heating doesn't work,(NOT GAS OPERATED). Just hear a click sound on the inside part of the system when I switch the thermostat to the heating position but nothing happens.I also switched it to fan position but just air comes out but no heat. I wonder what and where the problem could be. The Unit outside on the balcony is new.Where is the heating element, on the outside unit or on the inside part of the central air where the filter is at. Thanks.
