R22 Charging question

Postby tekgrl79 » Fri Sep 30, 2011 8:50 pm

I had a friend help recharge my system which is a 3 1/2 split unit, however I noticed when he did he would tip the jug upside down and fill liquid on the low end, the question I have is we have noticed since then it loses alot of freon, and shiney oily residue on the bottom 5 coils on left and right side of tend to get that way before it starts freezing up and causing it to be low again, could the liquid on the low end cause this? if so would pumping the system empty and recharging it the right way help? Someone told me you dont put liquid in the low end and I was wanting some advice or help.

Yes, charging with bottle upside down is prefered. This does not mean he actually put liquid into the compressor. The liquid flashes as it goes through the guages, the hoses, the shraiders, etc..... That bug of a leak is something he should have found though.

Seems to me that with R22 he should not have done that. He could easily have got liquid to the compressor where the compressor could have caused an intermittent pressure spike thus causing a leak. R22 should NOT be filled with the tank upside down ie. with liquid.

yea right, if you do it right it won't hurt anything. You are just trying to quote you textbook.

hmmmm its my understanding that if the system is low then you leak check with soap bubbles before you add more , and when you find the leak you fix it first then add more . just saying

well mti it is wise to charge with r-22 vapor if you have the time and there is enough pressure in the bottle. Also, I charge with liquid when the system requires a lot of freon then when I get to where it needs to be I change over to vapor that way I can zone it in just right.

Ahh how life is perfect when you read the book. In reality most leaks are difficult to find let alone fix. In some cases yea you can find them but what if the leak is in the evap or condenser coil where it's very difficult to repair. Maybe the people can't afford new equipment or labor to repair hard to find leaks. In most cases fill er up get paid and wait till next year to either do it again or replace the equipment. You can clean my truck now.

try doing it in an attic on your side with no breathing room. Plus that coil in class has been leaking for the past ten years. everyone knew where the leak was.
