I've had several people tell me to recharge my A/C as a liquid by turning the cans upside down (engine off) and filling into the High and/or Low side.
Can someone give a more detailed explanation of this procedure. Are there any benefits? I was told it is much faster. Can all cans be filled in this manner, or only the first one? Any ideas?
I know nothing...seriously
Do not fill as liquid into the High side. First: recharging from replacing some part in the system? Was the system evacuated and does it hold vacuum? Always post vehicle information you are asking about
At 2, I went home with a 10. At 10 I woke up with a 2 !!
You can charge one or more cans into the high side as a liquid WITH THE ENGINE OFF. Engine running and compressor engaged, you have to charge as a gas through the low side. It is indeed faster to charge as a liquid, and this method is better for the compressor since it is running with a greater percentage of the total charge, thus better oil return. I've never been able to get more than part of the first can in as a liquid, but then again, none of the systems I've dealt with held more than 2.5 cans.
