Furnaces and other heating systems may have a lot of complex mechanical components, but the basic premise of how heat is created is simple to understand: fuel is burned to generate heat. Or, in the case of electric furnaces, electrical resistance generates heat energy. But “cool” is not something that can be produced or generated: it’s not an energy.
While electricity is used to power an air conditioner, this cannot magically produce cool air with the help of a fan alone. It’s refrigerant, a chemical blend you may call Freon (a brand name), that does the job. So if it cannot simply create a cool energy to chill the air, how does refrigerant work? We tell you a few facts homeowners should know about refrigerant in today’s guide.
