In this day and age, appliances and electronic devices are most likely to make use of aluminum components. The primary reason for this is that aluminum is the most easily sourced material for electronic components, and so it’s the ideal go-to metal for most manufacturers.

However, even though that is the case, recent discoveries have shown that instead of aluminum, copper is the better option for electronic devices, particularly HVAC systems. This is primarily because aluminum is prone to bacteria and molds. And when the HVAC system is affected by bacteria and molds, it’s incredibly difficult to get rid of them because they are most likely to be found in the areas of the system that are dark and hard to clean. This would then lead to more accumulation of bacteria and molds, which would eventually lead to the breakdown of the system.

Fortunately, copper seems to solve this problem of bacteria and mold growth. Research has shown that copper surfaces actually hinder the growth and multiplication of microbes. In other words, copper helps keep the unit safe and in great condition for a long time. And because of that, copper components are recommended to be used in HVAC systems.

With all of that said, it is then your duty as an HVAC professional to equip the HVAC systems you’re offering to your customers with copper components, especially insulated copper tubes. This is because an insulated copper tube will help prevent the loss of heat or cool air that is necessary for any HVAC system.
