AC slow to turn on

I had my thermostat on the upstairs AC unit replaced as it was slow in turning on when we lowered the temp. After one month, the new unit is doing the same thing. It took 4.5 hours for the ac to turn on. I turned the unit off and then on again and after 45 min it finally turned on.

It could be several things by that description.

Remove the stat and jumper R+Y+G and see if it comes right on. Then undo them and wait a few minutes and put them back together and see if it comes back on.

Do you have a multi-meter and know how to use it??
