the mere sound of the air con when tuned to the max freaks me out
never ever that i tune it to the max

air cond temp turned to the max lah.....not the fan.....

the sound comes from the fan....which is controlled by the fan speed knob....

TS was referring to the temperature knob......

they myth depends on how to look after the air-con. just like your engine, it needs periodical service and maintenance. so compressor oil and air-con flushing and freon maintenance should be kept maintain all the time. if your compressor is running low on lubricant, it will breakdown early. if there is no frean gas due to leakage, then the compressor will have trouble working properly. and if there is blockage on the airway. then the compressor will work so hard that it will get faulty soon. for me, leaving on to the max is a need, cause i prefer not to sweat while the air con is working either.

if not mistaken, the air-con works accordingly to the timing of the engine. when the compressor is working, the timing of the vehicle will increase. correct me if i'm wrong

agree....just turn on the air cond and uselah....otherwise.....buy car without air cond loh.....

regarding the service thing....i do not fully agree......

nowadays air conds are designed to last long......just use only....once the air cond not cold enough....then start to service it like changing the spoilt parts......

i have 4 cars at home and I can't remember when was the last time I serviced my car air cond.....never got leaking or the air cond not cold yet.......iswara already 5 year old, hyundai 3 year old, kia 3 year old, kenari is 6 year old.....and the last wira before sold, changed when it was 5 year old (the cooling coil spoilt) and sold it at 10 year old without air cond problem.......

air cond service is not really necessary like changing the gas for example.....if the system is working properly...no need to change gas....the gas will not deteriorate in the system.....if have to often add gas meaning the gas is leaking so just change the spoilt part......plus once you start to change, better do a full inspection on the whole system and change any other parts that looks spoilt too.....else....the good parts will start to spoil faster as it needs to work more to compensate the not so good parts......

err...nolah....it won't affect that much....the air cond turned on with max and without max makes little difference.....most difference in petrol comsumption is when you don't on the aircond at all....

anyway.....i have never turned on my temp settings to max before because my car no need to do so also cold enough already thumbup.gif

Old cars have the hot water of the engine flowing into the AC system as a heating system. The compressor is on all the time and the hot water is used to control the temp. If you crank it up, the hot water actually gets cooled by the AC so the engine can get frozen (so to speak).

Also, there is no timing change when you turn it on. The throttle is increased to compensate for extra load sorta lke you tekan a bit more yourself every time the compressor is on during idle

Fuel consumption figures will increase but then how much depends on a few things.

- the car - cos different car have different engine output so it will affect the consumption differently

- the guy who put the gas in - cos if the guy was being a bit cheeky that day and didn't use the meter relying n the windows to check for bubbles then most likely he over pressured your system causing your petrol bill to go up.

Take note though maxed temp and low fan can cause the AC system to ice up. The cooling coil is so cold cos the fan is slow enough for the temp to continue dropping that it becomes a solid block of ice. It will slow and make the air coming out warmer. The only solution is to of the AC but leave the fan at full blast so that the air can melt the ice.

well said.....probably the most comprehensive explanation in this thread.......
