Triple evacuation is performed in HVAC systems primarily to remove:

Air
Contaminants
Moisture
Refrigerant

The correct answer is: Air

Triple evacuation is a critical process in HVAC systems to ensure the removal of any air present in the system. Air inside the system can lead to several issues such as decreased system efficiency, potential contamination of the refrigerant, and increased likelihood of system malfunction. By conducting a thorough evacuation process, technicians can effectively eliminate any trapped air, ensuring optimal system performance and longevity. This is why removing air is the primary purpose of performing triple evacuation in HVAC systems. In regard to the other options: - Contaminants: While it is important to remove contaminants from the system, the primary focus of triple evacuation is to remove air. - Moisture: Although removing moisture is crucial to prevent corrosion and ice formation, it is not the primary reason for performing triple evacuation. - Refrigerant: Triple evacuation is not primarily performed to remove refrigerant from the HVAC system.
