Im new on here and this is my first post. Im looking forward to learning much from you guys.
Im new in the HVAC field, just about finished with school.
My question :
What is the most reliable way to find out how much refrigerant is in a residential system ?
I would think recovering the refrigerant and weighing it will obviously be the most accurate. Then you know how short or overcharged the system is, right ?
My instructor said the only way it should be done is by taking superheat readings
Can you please advise ?
