Hello, it is possible that too much refrigerant was added, however in order to tell I need to know what sort of configuration you have, there are a few dozen,

Does the entire unit sit outside? or is there an inside furnace or air handler in a closet, attic or garage about the size of small refrigerator as well?

Is the noise similar to what can be heard when banging to heavy cast iron pots together? or two forks? Describe the sound in detail.

Stand as close to the source of the noise as you can, try inside, and try outside and tell me which is loudest.

We can go from there, if I miss you tonight I will pick up your response first thing in the morning.
