when I turn thermostat to heat cold air is blowing. What could be the reason?

I'm a first time home owner and now that its turning cold here, I flipped the button on the thermostat from OFF to HEAT. I am in manual mode and set the temperature to 68F. What I see is that cold air starts blowing through my vents making the rooms even colder. I also hear the outside compressor also running - which I thought runs only when the air conditioner is turned on summer


Could the whole heating and cooling system be working opposite? Cools when HEAT is on and heats when COOL is on?

It's possible there's something wired incorrectly or a malfunction.  What happens if you try setting the switch on the thermostat to cool?


There are two types of basic heating systems.  The first burns fuel (natural gas, propane, fuel oil).  The second is a "heat pump" and essentially works like an air conditioner in reverse.  If you have a heat pump, it would be normal for the outside condensing unit to come on.
