Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics. It's 100% free, no registration required.

My Co-workers and I are trying to figure this out, but can't think of a logical answer. It's probably an easy one, but I'll ask anyway- Ok, the heater is set at 73 degrees. The a/c is set at 73 degrees. Why does it feel warmer with the heat on if they're both 73 degrees?

1) Maybe it's your imagination
2) When the heater is on, its cold outside, so maybe it feels relatively warmer inside (and conversely for when the A/C is on)
3) Maybe the cold air from the A/C has more of a chilling effect than the warm air from the heater has a warming effect, thus making it feel colder with the A/C
4) Maybe something about the aerodynamics in your building i) increase the draftiness when the A/C is on (or its warmer outside), or ii) cause the thermostat to measure a lower temperature when the heat is on
5) Maybe the system is designed to over-heat more than it over-cools
6) Maybe something else
