Why is 68 degrees on a heater seen as normal, while 78 degrees is normal on an Air conditioner?

I think it’s because the air conditioner doesn’t heat up the whole room as efficiently as a thermostat, so the air near the air conditioner may be close to 78 so it will shut off, and the middle of the room will feel perfect and the other side might feel colder

Heaters are on when the outside is cold and people are typically in warmer clothes – so a comfortable ambient is cooler so that folks don’t feel hot.

Air conditioners are on when the outside is hot and people are in less clothing – so a comfortable ambient is warmer so that folks don’t feel chill.

Also, both devices use a lot of power. It costs a lot to heat up things when it is cold and cool down things when it is warm. If there was a “perfect” setting for temperature, it would cost a lot to maintain it. So a compromise is slightly less heating when it is cold and slightly less cooling when it is warm and this saves energy.
