Air Con Gas

I put my car in for air con and apparently I have to have evaporator replaced which is a common thing so my question is can it be replaced with something better so I don't have to replace in another 7 years thanks Phil

Is it a common failure?

Mine's 15 years old and touch wood is still ok.

And my 2004 just had its evaporator replaced so that's about 13 years.

i replaced mine earlier this year, i mean last year.
they corrode and clog up over time.

not sure why you quoted me LuckyLes,,
maybe my inference wasnt plain,,
I am going to actively pursue LPG based air-con gas for my next refill,, (using a qualified person)
the last line was a pun on me ALREADY carrying around 130 odd litres of lpg,,,



as for the amount in the air con going bang [bigrolf]

It works fantastically and seeing there is only 220CC in there, you would be unlucky for it to burn.

Seems a losing argument about catching fire considering the D3s High pressure fuel pump blow ups and the flammability of coolant.

I would like to see some evidence of numbers of aircons exploding in real life vs fires from fuel and coolant , batteries in Rangers and DPFs in Rangers etc.
Also all domestic fridges now use LPG based gas and you don't hear of many house fires vs unattended heaters etc..

I am a trade qualified MM and it was going to cost $880.00 to get licensed to get HCF gas or should I say to just be able to by it. The Hychill way is the way to go. Anyway most fridges and new cars now have HC gas in them. Even better for the environment so they say and not as hard on the equipment as well so also less chance of leaks in the first place . As to catching fire , every can of deodorant , fly spay, WD 40 etc uses the same or similar gas.

A dirty evap can be cleaned, corrosion depends on the environment.

Refrigeration evaporators can corrode badly depending on the type of stock being cooled, I've had an aluminium finned, copper coil evap corrode through in 18 months in an abattoir. (Hide room + guts)

AIr con ones have far less issues, generally lasting up to twenty years, or until the system is replaced.

it still worked, just was below efficiency. i dont bother cleaning, cheap enough to buy a new one and know its super clean.

Hi Rick,

For my education, how much work is involved in getting to the A/C evaporator, in order to clean it?
Does it require removal of a fair part of the interior dash-panel (beneath the windscreen, on the inside).

Quite apart from any corrosion or refrigerant leakage (which I don't think I have), it seems likely that dust, fluff and insects etc would gradually clog up the heat-absorbing core.
So, depending on the effort involved, it might be worthwhile maintenance every, say, 5 years or so.
Or is the system arranged so that this is not actually a problem?

Cheers,
AndrewMilne

Andrew, I've never pulled the D2 dash apart and never really want to!!

I'm a refugee from a Defender, and I removed the a/c in that years ago!

I'm in the business where we regularly (mostly I try and get the apprentices to do it) clean coils, both condensers and evaporators.

We use pretty aggressive chemicals on the condenser, and food grade ones on the evaps.

If we can't wash them out with a hose we use CO2 to blow them out.
The chemical I favour for evaps is spray on and leave.
The condensation rinses the coil of the detergent and drains the dirt away too, unless it's really packed with filth.
Then we spray them out.
