Switching the thermostat off could account for the two-minute delay
while the display flashed. The subsequent click shows that the
compressor was getting the "start" signal.
My guess that it was a bad contactor was ignorant. It's usually the
capacitor. They can lose capacitance over the years. If the compressor
starts sometimes but not others, the capacitance is probably marginal.
Replacing a capacitor seems like a DIY job. Buy the right size and
switch off the breaker.
delay in starting the indoor air circulating fan and the outside
compressor and cooling fan, I don't remember now how long. If I go from
off to heat for a couple of seconds and then quickly go thru off to
cool, the compressor and fan and indoor air circulating fan all start up
immediately. I have been doing this for years, that's why I don't know
how long the delay is when going directly to cool mode, but it hasn't
seemed to have harmed anything.
Try this -- about 2pm tomorrow, turn on the heat, then walk over and
stand in front of the fan. Let us know how it works out.

I guess the confusing part is that every thermostat I've owned, the only
time there was a delay in turning on the compressor is if the compressor
had shut off within the last 5 or 10 mins. Then it delays to give the
system pressure time to equalize. Otherwise, whether you go from off, or
heat or just lower the thermostat, the compressor starts up right away.
I now have an electronic thermostat (which enforces the delay), powered
by the indoor unit. When I open the cover to clean the filter, the 24VAC
is cut off. No matter how long it takes to clean the filter, there will
be a A/C start up delay.
BTW, It's actually cooler outside right now (66F). I have the A/C off
and back door open. That's unusual for summer in east Texas (where
September IS a summer month).
