Refrigerant and Freon questions
Canonical HVACentric knowledge for all questions on this topic.
DIRECT ANSWER
A sealed cooling system does not consume refrigerant like fuel. A low charge can indicate leakage, an earlier service issue, or an incorrect initial charge, and adding refrigerant without evaluating the cause may only postpone the problem. Refrigerant work requires appropriate equipment, procedures, and technician credentials; ask for documented findings before approving a recharge or repair.
