So we are in the summer and I noticed that when I turn off the AC it doesn’t take more than a few minutes, sometimes even less than that (especially in the car but also in the house) to feel that the house/car is warm again. why does it get warm so quickly?

Because heat transfer. You have a pocket of cold air in your house/car surrounded by a large mass of hot air. The overall temperature has to balance out. It’s the same as if you were to unplug your fridge, it won’t take long for the ice to start melting and for the cheese to smell bad.
That’s the rate that heat has been entering all along. The AC has just been countering it by removing heat at the same rate. As soon as you turn off the AC and stop that heat removal, the heat keeps streaming in at the same rate it had been all along. Except now none is being removed so the temperature goes up. If it seems to be warming up quickly, that just goes to show how much work the AC had been doing for you all along!
Heat comes through windows. Think of an ant with a magnifying glass. No cold air. Cold air go bye bye. Because now heat in car and house. With proper insulation the coldness will stay longer. Blocking windows will keep hot sun out
It could be that just the air is just cold but the furniture and the walls are still warm. Especially with the car. So when you turn off the air conditioner all the items in your room warm up the room air very quickly.
Now if you continuously air condition your home it probably won’t do this because everything in the home will be cold.
