    Warm/Cool air is only coming out of my furnace.
    Now that fall is here I tried to turn on my gas furnace.
    However it is only pushing out warm air.
    My boyfriend and I checked the fans, they appear to be working. We checked the pilot. That is working fine as well. Also per the light on my furnace everything is working normally. Is there any remaining reason why it would only be pushing out warm air? Please help.

    Warm air is what you want to heat but not enough warm aie can be a different problem. Is the thermostat turned to heat and the temperature set high enough for it to come on?

    The thermostat was turned up to 80 and was on heat.

    If the main power is on and the thermostat is set to heat it should turn on as long as you have gas being supplied to the unit. Do you have a working knowledge of electric and a meter to test voltage with? Also what is the brand and the EXACT model number.

    Test 115 volt power to make sure it is getting to the furnace from the main electric panel. Then check the transformer and make sure it is putting out about 24 volts.

    If the unit has a ignitor that glows to light off the pilot check it to be sure it is good and also make sure the circuit board is supplying power to the ignitor when there is a call for heat.
