My central heating unit is blowing out cold air

What do you want to do?

Turn the stat from ac to heat,, and fan on auto


What was the question

I think it's a trick... I'm suspicious...

More info. Do you have hot water, is it cold outside, is it warm inside, does your car start. Have you been eating more than usual? Does your dog howl at the moon. Can I get fries with that shake. How many blondes does it take before I go brunette. I just can't say, without more info. Just way to many options.
