Since it's new, call the installer/service provider.
Tell them that you have a concern and that you'd like it checked out
before something goes bad.
The call should be covered under the warranty. At a minimum you'll
have your concern documented in case it gets worse later.
Since most of us have a hard time hearing "clunking sounds" over the
internet, and your idea of "slight" might be very different from ours,
I suggest that you get a professional to come listen to it.
A *slight* clunking noise on startup and shutdown must be the low voltage
holding coil in the contactor doing its job - nothing to worry about. Two
pieces of metal clasp together by an electromagnet, as they were designed
to do, and make that sound.

yOU HAVE all MISSED IT. tHE COMPRESSOR UNIT IS RUBBER MOUNTED, AND
THE STARTUP TORQUE MAKES IT JUMP IN THE RUBBER MOUNT - MAKING A
"CLUNK" - AND WHSN IR SHUTS DOWN ALL THE ROTATING MASS STOPS AT ONCE
AGAINST PRESSURE, MAKING IT ROCK IN THE MOUNTS AGAIN - CAUSING A
"CLUNK". nOT AT ALL OUT OF THE ORDINARY - PARTICULARLY WITH THE NEW
Excuse the mixed caps - I hit the shift lock instead of the shift
and I',m too lazy to retype it all.
