how can you tell if you have low refrigirant?

[spyghost]

hi,

are there any other ways of telling that you are running low in refrigirant besides loss of cooling?

in my case kasi, i do not feel any loss in cooling, but here's the observation...

whenever the a/c engages (the compressor turns), the engine would idle erratically (even though its running at 900 rpm). no noise in the compressor. as for the frequency of clicks (engagement of the a/c clutch), i can't tell.

try to look at the dryer. usually it has a clear glass on top of it in which you can see the refrigerant. if the refrigerant is somewhat bubbly while the a/c is running, it means that you are losing refrigerant. hope this helps

for how long should the a/c be running? or should it be evident as soon as i turn it on?

Pag walang refrigerant sa system, the compressor wont turn on

sa window sa dryer it should have a clear to a few bubbles it means ok pa ng freon level. pag puti na sa sobrang dami ng bubbles bawas na ang refrigerant mo.

mga sir is it normal na pag naka idle hindi masyado malamig ang a/c for diesel engines ..?

sorry double post...

pag low na po ang freon yung A/C clutch nagpapatay sindi and yung idling up and down din sumasabay sa compressor. and pag totally wala ng pressure sa A/C sytem, d na mag e-engage ang clutch dahil wala ng contact sa pressure switch.

ang nagcocontrol naman sa idling whenever u turn your A/C on is either vacuum on old model na car and sa newer model naman yung IAC (iddle Air Control).
