The short answer is that it's what it was designed to do. It is so designed in order to keep an indoor area at a constant, comfortable temperature.
Inside of the thermostat is a coil. The coil expands and contracts with the temperature. When the coil expands to the point it's supposed to, it makes contact with an element detached from the coil, thus allowing an uninterrupted circuit to be made, which in allows power to get to the HVAC system.

In a central heating unit why does heating element keep coming on when the heater is not on?
Sounds like the thermostat is set too high so the unit is calling for heat... If the thermostat is set normally then the unit has a fault. Repairing an air conditioning unit is not a Do-It-Yourself job. The best advice anyone should give you is to call a licensed Heating Ventilation and Air Conditioning (HVAC) technician to check the unit for you. If it is faulty it can then be decided if it is worth spending money to repair it or if it makes more sense to replace it with a new one.
