NAPERVILLE, IL — Bob Forty knows all about condensing coils. In fact, he knows a lot about everything in the world of heating and air conditioning. As president of Energy Services Air Conditioning and Heating Co. here in Naperville, and a 30-year self-proclaimed student of the hvac industry, Forty has seen a lot of trends come and go.
One of the trends he’s not happy about at all is condensing coils that are made from aluminum (aluminum tube/aluminum fin). He notes that copper tubes with aluminum fins, which are the usual choice for condensing coils, are superior to aluminum because of copper’s superior strength, reliability, ease of maintenance, and excellent heat transfer characteristics.
