Air conditioning and jerking

Hello, I am now driving the Crv IV 2.0 four-wheeler as a petrol engine since the end of October last year and am more than satisfied with the slightly rough switch from the first to the second gear. But now I have noticed what and wanted to ask if this is also the case with you. If the air conditioning is running, the car drives more restless, just in the load change area, if you give only slightly gas and then go off the gas. When I speedily notice through a jerk at the accelerator pedal that the compressor turns on. Feels like the Vtec switching. The compressor switches when it is warm about all 20 seconds. At the same time, one hears a hissing in the interior, sounds like one blows into a straw. If one drives without a climate and switches the one feels the first moment as if one pulls the handbrake lightly. Am I only sensitive because one could not notice this with my old diesel, or is there a defect on the air conditioning. In winter I hardly used the air conditioning system, because it is difficult to say hello to the dealer.
