The Role of Copper in Air Conditioning Units

As an expert in the field of air conditioning, I have been asked numerous times about the importance of copper in these units. Many people are surprised to learn that copper plays a crucial role in the functioning of air conditioners. In fact, the amount of copper in an air conditioning unit can vary depending on several factors, such as the type and size of the compressor. However, on average, a three-ton unit contains about three pounds of copper, while a window unit can have anywhere from 3 to 5 pounds.

Let's take a closer look at why copper is so important in air conditioning units and how much you can expect to find in your own unit.
