AC leakge 一般怎么解决？ 下面是诊断书

Refrigerant pressure low on both sides. A-coil freezing where TXV connects. Got hits with sniffer. Would require in depth diagnostic to pinpoint exact location of leaks.
Refrigerant pressure: 71/270 psig

 

Option 1: recharge unit. May produce cooling for short term but does not fix leak.
Refrigerant: $99/pound. System holds 10 pounds factory charge. Some additional may be necessary to adjust for long line set.
*No guarantee how long refrigerant will remain in system.

Option 2: Internal diagnostic. Regular $240, Club member $216
Refrigerant: $99/pound. System holds 10 pounds factory charge. Some additional may be necessary to adjust for long line set.
Plus cost of repair or replacement of faulty component. Cost dependant upon results if diagnosis.
*Added 1 pound refrigerant for diagnostic purposes. Pressure barely changed. Indicates that large portion of refrigerant charge is missing.
*Freezing on coil also indicates low refrigerant
Customer chooses to take no action at this time. Will consider options first.
