I just topped the aircon up with one of those bottles from Halfords. I already have the connector with the gauge though so it cost me £34.
My aircon is now fine. But I was able to check mine first with the connector I have and I could see that there was gas, just not enough.
Thanks
But how much. You can't tell. That's one reason why these refills are a waste of time.
If the refrigerant has leaked out over time, something else will have replaced it, and this needs to be removed before refilling with refrig. That's another reason why these refills are a waste of time.
TBH, the money spent on these is better spent on getting specialists to do it - unless you have the correct equipment, which isn't the refill adapters that Halfords sell.
I can tell as the connector I have, which I never said I got from Halfords, has a pressure gauge. This told me that the system had gas in it and it was just below the required amount to make the system run.
If it had told me anything else then I would have either done nothing and lived without aircon or taken it to a specialist which I don't have time for.
Guess what, I put some gas in, not the whole bottle by any means, and now I have ice cold air conditioning.
Here was me thinking this was a friendly site....
