Aircon Compressor problem

I have a Toyota car having problem with it's aircon. The aircon compressor does not automatically works when I open my aircon. It will take minutes of driving before it works. This causes my rpm to soar during the initial driving. What can be wrong?

Im not that familiar with cars, but if this is a new (90 or newer) then the RPM going so high is because the fast idle switch. It does this to compensate for the extra power being used by the compressor, which isn't coming on at first. Is the electric fan coming on for the condenser coil at the same time as the compressor? You should have 2 fans, one is for the radiator water, the other is for the A/C. There are temperature controlled sensors for these fans on some models. Its possible that may have something to do with it.

Too hot little cold


Very possible your condenser is extreemly dirty and is turning off on a high pressure cutout. suggest you clean out condenser with compressed air. Brushing is not enough. also, check if condenser fan(at the compressor) is working.

Not heating. The fan blows, but no warm air. RHEEM RCGA-60A1AS24


Please check if the compressor is running, if not, then
there is no warm air generated. Please contact the RHEEM dealer about it. Aircon compressors are run
with a thermostat. So, you may try setting the aircon
thermostat to maximum, so that the compressor run,
and you can have your warm air. May this info help you.

I have a honda civic esi 93 model,when i turn on my aircon the idle drop down,there is no problem with the idle when the aircon is not running,do i need to replace/check something to my aircon system?


As long as the engine doesn't die that is pretty normal for those cars. earlier a/c systems had much heavier compressors and took an extremely large amount of energy to turn. that is what causes the idle to drop. If you do experience anything other than that then i would have it looked at. If it makes the engine pull way down then you could be having compressor issues. hope i helped and good luck.

Noisy Aircon


Your compressor ismounted or rubber feet. If one or more of these rubber spacers is gone or loose you need to come up with some more. If these are still n place its possible that the compressor (which is mounted inside the black oval or round case) may have a broken spring. In this case its compressor time Im assuming your fan is ok as you say its only when the cooling is on. Only 4 things move on the AC 1= inside fan 2= outside fan 3= fan motor and 4=compressor& compressor moptor which are in 1 case. 
If you need to know more add on more information but I believe if youve gave me all you can thhin of its something to do with the compressor. 
OH yes FYI if the outer case of the compressor is round you have a rotary compressor and they arenatorious for being loud and viberating even when new. If you decide its inside the compressor Id suggest replace the whole thing cause the compressor viberation causes tyhe copper lines to become hard and can crack eaisly.  Hope this helps. PLEASE Grade me ACCORDINGLY and good luck.
