Default 2010 Civic EX: A/C temp control adding heat to air

I've got a 2010 Civic EX.

When I start the car and turn on the A/C with the temperature control
set to coldest temperature setting, I notice that the air coming from
the vents still isn't cool enough.

But if I then turn the temperature control up to the hottest setting and
then back to the coldest setting, maybe cycle that a couple times back
and forth, it seems to "trick" the system into producing the coldest air
again.

Any idea what could be causing this?

It may well be,
But I would still like to know what the problem might be, so that I can
tell if the dealer's repair shop is fixing it properly.

Actually, you want to avoid the usual dealer finding -- cannot duplicate the
problem. That changes once the warranty has expired.

If you aren't sure if it's still in warranty, you may have bigger issues.

Take it to the dealer. CDP? Take it to an independent and ask for an
estimate. Take it to the dealer. CDP? Take it to another shop for
another estimate. Dealer. CDP? Lemon law.

An object's desireability to a dog is directly
proportional to its desireability to another dog.

a) have you just tried waiting a bit? If you're using re-circ, the
air it's taking in to cool will still be hot, maybe even hotter than
outside. b) how hot is the outside temperture. The A/C can only cool
so many degrees below either the intake or the ambient. The shop
manual should have those numbers. It's usually like 10-12 degrees F
below interior (assumes re-circ) or about 15-18 below ambient. This
is due to the magic of entropy and the ability of your heat engine
(A/C compressor/condensor) to shed heat.

I've noticed this even on mild days. And even after having the A/C on
for 20 minutes. But after those 20 minutes, if I do this trick of
cycling the dashboard temp control to hot and then to cold once or
twice, the A/C air gets definitely colder. Somewhere I imagine that a
little bit of hot air is being mixed with the cold air, and that cycling
the temp control shuts off all the hot air.
