There are other problems besides the lower stability, as it will shift the COG up and reduce overally stability of the boat, as it heels, the 100 lbs. of the AC unit essentially cancel out a part of the righting moment generated by your keel.
The biggest of these is the fact that the AC unit will be a weak point in heavy seas or in the case of a knockdown. If the AC unit shifts, breaks or falls out, it will allow a lot of water to come into the cabin, and if you're on a ballasted monohull, downflooding is a strong possibility.
Also, the unit is probably not designed to resist the corrosive effects of a marine environment. There is a good reason that WM sells carry on units, rather than permanent installations. Most people do not have a sufficiently large battery bank to support running an AC unit, except under shore power—so why carry the weight when you're sailing??

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
