It means there's a leak, and filling the system with refrigerant just means it'll leak out again. So, what's supposed to happen is that the leak is located and repaired.

What is a vacuum in physics?

A system is said to be at a partial vacuum if it is at a negative pressure (pressure less than atmospheric pressure). When you use a straw, the partial vacuum created inside the straw is what causes your drink to travel up the straw and into your mouth.A perfect vacuum would be a space with nothing in it and a temperature of 0 degrees kelvin. Practically, however, we can only achieve and work with partial vacuums or pressure differentials. Even what we call outer space is only a partial vacuum. Rule of thumb: Nature hates a vacuum.
