filled a few weeks ago and just turned on my furnace today. It is set on heat and only cool air is blowing out. Filters are clean and I have daycare kids coming shortly. What can I try to get my furnace to blow hot air?

The pilot light might be out
check it to see if the burner is lit
is the pilot light working?
is the fan set on auto ?
thermostat set at 70 deg or more ?
If it is a standing pilot model furnace, make sure the pilot is lit, and the thermostat is set to “heat” not “cool” and you have the temperature set higher than the current room temperature.
If it’s a newer electronic ignition type, try moving the thermostat all the way to its coldest setting and then back up to full heat. This will make the furnace go through it’s ignition cycle. You should hear a fan come on then you may hear a snapping sound several times. That is just the ignitor trying to light the fuel. If it it has a hot surface ignitor you won’t hear the snapping. If the fan shuts off again after 20 seconds or so, then the furnace is not lighting. Don’t confuse the fan that pushes air out of your vents with the venter motor on the furnace itself.The circulation fan may run all the time, but there is a fan on the furnace that pushes the spent combustion gases out of your house if it is a newer furnace. You can try this 2 or 3 times, but if it doesn’t light don’t keep doing it. There is several things that can cause the furnace to not light, but none of them are something you should be playing with yourself. Call a technician if these things don’t get you going… Good Luck with it!
Check the valves to ensure that they are in the right manner. Propane fireplace are sensitive and dangerous if they are not handle in the right manner.
