im stupid. what now?

josh870 · May 18, 2015

i just recharged my A/C, there was zero pressure, but me being a genious i forgot to shake the can. it only says "shake vigorously" a few dozen times on the can... should i take it somewhere that can drain it or just leave it be?

I would just shake it (vigorously) then hook it up and see what happens

josh870 · May 18, 2015

but it is full now, if i do anymore it will be overcharged

Shake vigourously is there because they added in a corresponding amount of oil in the freon. Your can could of blown all the freon out and left the oil. The oil is easy and cheap to introduce if you wish, If you did not do a solid evac and vacuum of the system the amount needed is slight if any...depends on what got blown or sucked out previosly. And dont worry, im stupid too, and I like good company

You could have oil injected at a shop. they can inject oil without evac/recharge. I wouldn't run the compressor too much without oil. Im assuming r134 and oil is whats in the cans?

The amount of oil needed depends on why the system was at zero pressure. Too much and you reduce your cooling capacity. Too little and the compressor runs too hot. Slow leak over the winter, no traces of oil on any of the fittings, and no changed parts, I say run it.

If it only took 1 can you are probably okay

That right there is signature material! :roflmao:

alright i guess i will run it for now. how long does it take to work? it still blows hot air. probably needs more than just the recharge

ehall · May 19, 2015

Did the gauge pressure go up any after adding the can? Has the compressor kicked on yet?
