compressor clutch motor engages/disengages every 20 seconds

is this the normal cycle of the compressor clutch motor while idling? just had the aircon system cleaned and recharged with refrigerant. (RA134)
thank you in advance,

No. Check baka overcharged. High pressure yan. Nung nagkakarga ba ng refrigerant, binasa ba nila condenser? If yes, overcharged nga yan

Is "what" normal?

If you have a friend or officemate who has the same car, have him/her start the engine of their car and turn on the AC. Observe the on/off cycle of the compressor.

thank you in advance,

as they said, "high pressure".
either they put in too much refrigerant, or you have a blocked tubing in your system.
bring it back to the shop. the solution might be easier than you imagine.

I believe it's normal. My Civic does it... as well as my Innova.

The cycle time gets shorter and shorter when the climate control has achieved the preset target temp.

On the Civic, it can go as short as 5-10 seconds on and/or off.

thanks... i guess it varies due to ambient temperature. when it is operating at high noon, the time the compressor clutch engaged is longer and shorter time when it is disengaged. early morning it is in the reversed order.

i just adjust the temp setting to the cooler temp.
in a non-defective system, this usually results in less of that engage-disengage clicking.
in a defective system, it won't change.
