Turn your thermostat to something crazy like 90F and go look at the A/C condenser unit outside. If it is running and cold air is blowing out of it then you have a heat pump. It is also common for it to get some ice on it.

If it is super cold out like below 30 you probably have backup heat and the outside unit may not work so it is best to try this on a day above 35-40.
