Is there any bleach-like odor when using these tablets, or any odor at all?

per the manufacturer--is biodegradable, non-toxic, and non-corrosive. i have not experienced any bleach odors. if there was it would not be applicable for the pump mechanisms that the water flows threw.

Can this be used with a window unit and where do I place the tablet? Thanks!

I do not use those tablets in a window A/C unit because like you said in your question, where do I put them. Those units have no drip pan that accumulates a lot of condensation, that condensation is released immediately to the outside. So, if the unit has a drip pan I would use them.

Where exactly do I put these tablets? Where is the condensation pump located?

A tablet like these will only be completely effective if placed in the drip pan itself. This usually requires removing the panel where you can access the coils. If you only place it in the drip line then it will just pass through quickly and any line before where the tablet is placed will not be kept clear. The drip line can even clog where the overflow shutoff valve should stop the AC from working (to prevent flooding) which will prevent the shutoff from doing its job and allow your ac condensation to backup and to overflow into the cabinet and anything below it.

Do the tablets have any specific shelf life?

There is no expiration date on the packaging.
