Customer Question

Hello, I have a 2003 A/C system. Basically a friend attempted to recharge the A/C system with refrigerant with just a can. I turned on the A/C system while he was doing this it just blowed hot air. The question I have is someone told me that I should have used a can and a half for this?

Ok to properly charge the a/c system you MUST evacuate the system and apply vacuum for minimum 30 minutes. Then you must charge it by weight which is printed on the label under the hood. Just adding a can or a can and a half will NOT get the a/c to the proper level. If there was already some refrigerant in there, you will need to check the charge level by using a/c gauges and the charging level chart below..

If the pressures and temperatures are in the range according to the chart then the system is fully charged, If out of range high or low, you need t adjust the charge level accordingly..

Keep me posted and let me know if you have any additional questions...

Thank you,
