How can the aircon be at the same temperature for both heating/cooling modes and feel different?

If its cold and you want it to be 21c its blows hot air

If its hot and you want it to be 21c it blows cold air

A) It’s either blowing hot air or cold air until the room reaches the temp you wanted. Not 23°c air or whatever you’ve set it to.

B) in cooling mode, the evaporator providing the cooling doubles as a dehumidifier. So you get cold dry air vs warm possibly damp/humid air.

Neither the heat nor cooling blows air the temp its set up… that temp is the target temp. Let’s say both are set to 72 degrees. When the temp in the room drops below 72, then the heat blasts hot air, about 100 degrees, into the room to mix with the ambient air until the overall air mixture reaches 72 degrees. For AC, when the temp rises above 72 degrees, then cold air, around 40 degrees, blasts out to mix with the ambient air until the overall air mix drops to 72.

When you’re cooling, the thermostat is one of the warmest things in your house.

When you’re heating, the thermostat is one of the coolest things in your house.

So any room with good airflow that isn’t close to the thermostat probably has 10 degrees of difference between summer and winter even with the thermostat set the same.
