How can I turn my central Air Conditioner into a heater also?
No it isn’t just installing a heating element. You will have to add on a furnace or replace the air conditioner with a heat pump. The furnace would replace a piece of equipment you have inside called the air handler. It could either be electric or gas depending on your choice. If you go with a heat pump it will both cool in the summer and heat in the winter and it will be electric. There may be some other slight modifications needed with a heat pump depending on the age of your current a/c.
