De-gasing A/c

[shotter]

Has anyone done this at home? Or know how to do it?

[TiTAN]

strictly speaking you are supposed to get it degassed using the proper machines so it doesn't vent to atmosphere. the elcheapo at home method is to just losen off one of the lines and wait for it to all leak out

[lachlanw]

yeah its kinda a major no no . like big fines . really big . like 5 figures big .

there will be a nipple on the pipe somwehere that has what looks like a tire valve cap on it . or one of the lines off or unbolt them

legal way: drive to local aircon place. ask them to degas aircon. hand over keys. come back after however long they tell you.

the job itself should only take about 5 mins, but depends on how busy you are. as to how much they charge i wouldn't know, but it shouldn't be too much.

make sure you stand back!!

Crack fitting... walk away, crack open a tinny of your choice... come back later!

[shotter]

Cool thanks guys. Thats what i was thinking but after the misses just got up me for thinking about doing it myself.... i will take it somewhere to get done.

shouldnt cost much, they will suck it out with a recovery pump into a bottle of waste R134a Refrigerant.... if your planning on removing air con lines and such you will need a new reciever drier when you put it all back together

[shotter]

ok cool. whats the receiver drier do for ya?

[89CAL]

ahhh shit lol.... it been to long since ive been taught air con systems

I googled it for you cause I wanted to remember what it does as well...

RECEIVER-DRIER

The receiver-drier is used on the high side of systems that use a thermal expansion valve. This type of metering valve requires liquid refrigerant. To ensure that the valve gets liquid refrigerant, a receiver is used. The primary function of the receiver-drier is to separate gas and liquid. The secondary purpose is to remove moisture and filter out dirt.

Air Con Information

So basically its for the secondary reason that you must replace it because it will absorb alot of moisture from atmosphere when it is disconnected from the system.

Oh cool. Thanks for that mate.

install high mount manifold...

let said manifold rub on air-con pipe while doing a skid = big bang + flame + bonnet lift = degassed

that way does sound more fun...... but more expensive as well lol
