Charge

Term from Air Conditioning Services industry explained for recruiters

A "charge" in air conditioning services refers to the process of filling an AC system with the correct amount of refrigerant (cooling fluid). This is a crucial task that HVAC technicians perform during installation, maintenance, or repair of air conditioning systems. When someone mentions "charging" or "recharging" in their resume, they're talking about their ability to properly fill AC systems with refrigerant, which is essential for the system to cool effectively. This process requires specific tools, knowledge of safety procedures, and often certification due to environmental regulations.
