Got my Honda City AC checked from HONDA Township. The mechanic checked through guage and physically touching the pipe, told me the AC is okay. However, I insisted on checking the refrigerant weight. Upon connecting with the vacuum machine refrigerant weight came out as 350grams (450g is recommended).
Checked the circuit in engine side for leakages, no issue observed during pressure test, held pressure for 15mins. No abnormality found, so refrigerant was once again made up through the machine to 450Grams. Didn't attach the cylinder for makeup and used the recovered gas. However, after gas makeup I am feeling the cooling has decreased.
Is it possible the gas added was contaminated (chinese gas recovered from other cars)?
