Air Conditioner on & off every 5 seconds?

Hi. My air conditioner goes on & off every 5 seconds when the inside temperature and outside temperature are close? Most noticible at stoplights. But I just sat and listened to it go back and forth 8 times every 5-10 seconds. Is this normal? Why would they have it kick in & out like that, couldn't they limit the shutting on and off by mixing hot air w/ cold or increase the temperature spread that triggers the unit? Something seems a little off here. It was 68 outside this morning with the climate control set to 67.

From October ServiceNews:

To provide adequate cooling for its high-performance,
turbocharged engine, the ’07 RDX
comes with a huskier A/C condenser fan than
what’s used in other Acura models. Service clients
may complain that the A/C runs loud, it cycles a
lot while the engine is idling and, when it cycles,
the lights flicker a bit. This is all true, but it’s
perfectly normal for this model and well within its
design specs.
The RDX’s condenser fan uses a 160-watt motor
with a 120-watt motor in the subfan. The TL’s
condenser fan, by comparison, has just an
80-watt setup. The RDX’s condenser fan runs at a
higher speed and decibel range to do its job, so it
sounds noticeably louder. And it cycles more
often than other A/C condenser fans to handle the
RDX’s high-efficiency evaporator requirements.

Great info. The thought crossed my mind also. Thanks.
