I get a blast of cold air when my heater turns on, is this a safety part of my heater? Is there a way to start the burner before the fan kicks on?

Need more info here What is the furnace? When you have a heatpump with a gas back up. there should be an outside tstat that will turn over to gas at a set temp. So now when you are on gas Id say its up to the gas furnace to say when the blower comes on so you get warm air not cold. If all is wired right then look for the fan control in the furnace . On the furnace board or fan limit control and see how it is set to come on. The burner should come on before the blower does.

Thanks Ed for the quick response. My T-Stat has "Heat" "Cool" and "Emer Ht" on the controls. My builder said just to use the "Emer Ht" setting for my heating needs. The outside A/C units don't come on. It appears to work like a regular Gas Heater, but I do get a blast of Cold air, about 2 minutes worth, before I hear the burners fire up. I'm not very savy on these things, hope this additional information helps.

Something is not wired/controled right. In emergency heat the burner(s) should fire before the fan comes on.

:wall: Sounds like there is a wiring problem, would it be a miswired problem, like wiring backwards.

How long does it take for the ducts to start producing warm air? If it's just a minute or so there's nothing you can do. It's just the air that's been sitting in your ducts getting blown out and replaced with warm air.

Now you said something though about the builder telling you to just use emergency heat all the time?? Why?? If the builder put in a heat pump and you paid for it then you should be able to use it.
