What is a periodic loud thumping noise coming from the air handler during the air coindioning phase?

AWOL cat in the blower wheel. LOL. You need to check inside the fan compartment and look into the fan to see if a piece of insulation or debris got in there and makes it off balance. The blower wheel could also be loose or damaged.

Or too much clothing in the dryer sitting next to the air handler.

Could be the blower wheel is loose on the motor shaft. or the wheel could be out of balance.

while not quite a thump but sheetmetal "pops" or bangs sometimes. Large panels do an oilcan action when pressurized and then when the pressure stops sometimes.

Yuri is most definitely correct.

If I may expand on what he has already stated: All it takes is for a small piece of paper to be stuck either in side the blower wheel or the outer surface of the wheel.

It could cause an intermittent knocking of the blower. Or it could become stuck in the wheel and make a continous noise.

I gotta go with nap on this one, a periodic thump says sheetmetal expanding/contracting to me. Debris or offset blower would be more or less continuous, right?

I would agree with the possibility but the OP described a "THUMP" not a "BANG" which is how I am used to hearing sheet metal expansion and contraction.

Last year I almost needlessly changed an inducer cause of an intermittent thumping.

But I wasn't 100% positive so I killed the power and pulled the inducer and put the stat to "fan on". The thump kept coming and going.

It turned out to be a cellophane cigerette package stuck to the outer surface of the blower wheel.

Hell, he charged him extra. He did clean out the ducts after all.
