Not fully T CROSS related but perhaps valid nevertheless. I found this question/answer in Honest John column this morning interesting,

QUESTION: Can a car sitting around stationary cause the air con to break?

ANSWER: Most air conditioning problems in cars are caused by lack of use, usually because the driver has switched the system off during the winter/colder months. Air con systems in cars are not designed to be used in this way. They should be switched on 100% of the time, otherwise the joints dry out and allow the refrigerant gas to escape. In the worst cases (if the air con has been switched off for a very long time) the compressor will seize and fail.

I always thought it was ok to run air con occasionally to keep everything lubricated in the belief that running it on every journey could considerably increase fuel usage. I must admit, I always turn Air con on nowadays owing to infrequent use of car.

I have been running mine once a week to keep any seals lubricated. My understanding is once the car is on a straight stretch of road the extra fuel consumption is negligible, just uses more in stop/start traffic.

Interesting comments..!... I must admit that I only switch air con on occasionally ,say, once a week, and then only for short periods..!.. Mental note " must use more often"...!

I have had air conditioning in every car I have had over the last 45 years and never switched it off, and also never had a problem with them. Admittedly I know people whoh have had problems with seals leaking, however I don't know anybody who switches them off either. In the winter a/c stops the windows fogging up so makes driving safer, and obviously in summer time we have them going all the time. I know if we have our temp dialled down to about 19 in the summer, the a/c is working a fair bit, but that's why they are there. Any time we get in the car after a shopping stint in the summer, it would be around 60 C for a few minutes before the a/c pulls the temp down. That's when your a/c would affect you MPG while it is working that hard. We might hav e v a slightly bigger compressor and condenser on our models over here to help cool a bit more gas to handle the higher summer temperatures. I am not sure how much the MPG varies with or without the a/c, I never worry about it. The only time I touch the switches is to close the inlet and go to recirculate if there is a smoky car just in front.

On my Mk4 Golf with Climate Control, I could see no significant difference in mpg on my standard 30 min commute - mixed roads - with it on or disabled.
Of course its never that hot up here in the North !
