After having the condenser replaced and the refrigerant charged, it takes a lo-oong time for the cabin to cool off. The air blows cold, but not icy cold like all my other cars. Is this normal?
AC Condenser Replaced/Recharged... takes forever to cool down!

What do the gauge pressures indicate? Was it a modern parallel flow condenser that got installed?
Are the fans working correctly?

There's a lot of things that need checking. All the aforementioned first and then check the recirculate actuator commanded and actual positions with a bi-directional scan tool like a Snap-On Solus or GM MDI2 and a laptop running the GDS2 software.

Aye that, laddie
Yes, dealer did it. Don't hear/feel clutch being overbearing.

To nobody in particular, these aren't 1980s pickups. They are way more sophisticated with loads of creature comforts and lots of little computers and more enduring too because of all this technology. A DIYer cannot work on these things without a dealer level scan tool. Without it, folks waste time and enormous sums of money guessing as to what the problem is when a scan tool could have told them or at least put them on the scent within a minute. Mine has saved me thousands of dollars and sharing it with others has saved lots of other folks money as well.

Yup, a good scan tool (I have Autogenuity w gm enhancement) and access to the full-service manual, they have enabled me to fix all kinds of stuff that would have cost thousands of dollars for a mechanic or dealer to fix... I've also needed to buy a variety of other tools, so occasionally, for a specific fix, it may get close to costing about what a mechanic would charge, but then I also have the tool to use down the road.

Yes, that is very precisely a good reason why your AC system under performs. But I've never heard a clutch fan make an odd noise. It just "does" its thing.

I probably called it wrong, but when your AC is on, shouldn't you hear some tick on the engine bay like something is cycling? Tick or click every so often?

The compressor clutch makes a little noise when it turns on and off.

Yeah mine stopped making noise. So looks like I found the problem

Thanks for all the input. The dealer thinks a dirty cabin air filter may be the culprit. It was only 6 months old but it was really clogged. We'll see over the next few days if this does the trick.
