if your AC is working fine other parts of the day, its not likely
there is anything wrong with it.

This statement is totally wrong. there are several ways an a/c can
fail and only partially cool

No, that statement is totally true. If the AC cools the house some
of the time, but not when the sun is high in the sky, then the house
isn't very well insulated.

Wrong!

If the A/C is undersized, it may be able to cool the home when the load
is low, but not when the load is high. The same result would occur if the
unit was properly sized, but air flow was restricted, or it was not working
to full capacity for other reasons. There are many possible reasons.

Frankly while insulation is important and should be up to standard, if
the installer did a proper install, he would have known the insulation was
substandard and increased the size of the unit (also informed the
homeowner.)

Give me a big enough unit and I can cool a un-insinuated airport hanger.
