So my A/C is hot, and I was going to pic up a can of the 134a refil crap. Till I read about this online, and in another thread.

Reccomends that you vaume the A/C system to remove air and moisture before putting a 134a can in.

What do you guy think? Anyone use this method?

 

TTT

 

when you expose the drier to the atmosphere it absorbs moisture. this will make the air smell funny. other than that, it should be ok to reuse driers.

the other concern is mixing oils. some dont like to mix and others are ok. it's best to keep it one type, but ive done 2 retrofits without vacuuming out the insides and havent had any problems.

if you are adding just r134a to an existing r134a setup, i dont think there is any need for concern.

Sounds good, any other opinions?

 

Any refrigeration system works better when there isn't any air mixed in with the refrigerant. Moisture is even worse - that's why they put a dryer in the system to trap & hold moisture.
