    Air con - needs regassing after 9 months 11th Mar 17 at 12:12 PM
    Had air con regassed last June. Just tried to use it again and it is not getting cold. Could this be an issue with how to regassing was done or does it mean we have a leaK?

    If it was regassed without any repair, then it must have had a leak.

    They operate much the same was as a fridge/freezer, gas can't get out unless there is a leak.

    Manufacturers generally recommend that you should run the air con for a bit every couple of weeks, presumably to prevent parts seizing up. Could that be what's happened here over the past nine months?

    Have you not used it since last summer? If not, I'm not surprised it's not working now. Use it all the time, all year round. The system contains coolant and a lubricant that lubraictes the seals. If you don't use the aircon for a long time, the seals dry out and coolant escapes.

    If you never use it, the gas leaks out gradually through the seals at the pump, you should use it all the time*, even in Winter, it simply stops working when the temperature is below freezing.

    However, you could have a leaky pipe, as for all you know, the gas all escaped in October.

    A regas at the fast -fit chains will test for a big leak, then see how it goes if you use it all the time.




    *All the time if you have "climate control" it helps keep the windows demisted, at least every week if you have the manual "press snowflake button for cold air" type.
    I want to go back to The Olden Days, when every single thing that I can think of was better.....

    How "cold" are you expecting it to be? It's not exactly sweltering outside.

    If you want to confirm whether it has a leak or not then take it someone who knows what they're doing, eg, not kwikfit.

    Fridges and freezers are welded or brazed closed with the motor inside. We have a fridge and a freezer which are both around 40 years old and run permanently in an outbuilding. Car a/c compressors are driven by a belt off the engine and so feature a seal on the shaft - that's the usual source of a leak especially if used infrequently. Many drivers are worried about the effect of a/c on fuel consumption but it's pretty trivial compared with driving style.

    My AC isn't used that much, once a week usually in winter. It doesn't affect the fuel consumption much at all, but it does make the engine noticeably less responsive.

    People saying about fuel consumption when using air con what about this one, my in-laws live in Spain and years ago someone told them about air con and fuel so they never use it you ride round in there car covered in sweat it's like sitting in a oven. It can be 40c outside but your glad to get out of the car because it's cooler outside than in.

    Generally, I don't use the air con when in the Med or Australia. I find that it stops you getting acclimatised to the ambient temperature. After a couple of days, the sweating stops and you don't really notice the heat.

    When I spent time in Australia with friends, they had the AC on "lo", which is basically shoving out freezing cold air constantly, rather than setting it to a reasonable temperature. You get out of the car into 40C heat and it's like walkng into a wall. The thing is, just like with heating, people think changing the thermostat to extremes will make things heat/cool faster.

    The other factor to consider is that, in the UK, aircon is actually at its most useful in winter weather. It dries the air, as well as cools it - the dried, cooled air is then passed over the heater matrix, so you can have warm, dry air. That's, very simply, the fastest way possible to demist windows and keep them clear.

    Mind you, given the number of people you see driving around in what looks to be a mobile sauna with a tiny porthole wiped in the condensation, people don't seem to understand that airflow is necessary, either...

    Yes, that's right if you turn the boiler thermostat up to an extreme it definitely heats up a lot quicker.

    Thanks everyone. We have used it during the winter but obviously not on a cold setting. Assume we must have a leak. Many thanks.
