    Goodman furnace not enough heat
    My goodman furnace will not keep up in cold temperatures. Can I increase the amount of heat it puts out. Seems like air coming from vents is not that warm.

    You cannot increase the firing rate of the furnace but a properly trained HVAC person with the proper tools can check and adjust if necessary.

    The furnace runs for 15 minutes and is only off for 5 minutes. Can this be a problem with my thermostat?

    Drafty house in the cold weather will do this. Mine is the same. I don't worry about it as long as I have heat. We went down to l5 degrees below celsius two days ago so didn't worry when I heard the furnace come on and off. (the old one would go off entirely!)It is a new high efficiency furnace installed this last summer. A new thermostat. It is a drafty old bungalow built in the 40s pretty close to Lake Ontario. What can I say. I live with it and thankful I can pay the gas bill.

    Yes it could but you said the furnace would not keep up in your first post? So why is it a thermostat problem now?

    The thermostat could be located in the wrong area.

    The thermostat could not have the wires sealed behind it with caulk or DUM DUM compound. This allows the cold wall air to have its way with the thermostat.

    The thermostat heat anticipator may not be adjusted correctly or the setup selection was improperly done during the install.

    Now I must ad this. Years ago it was acceptable for a gas forced air furnace to cycle up to 6 times in an hour but the real problem here is that you offer no other information. If it is 20 below zero your furnace is going to cycle differently then when it is 40 above zero.

    What is the brand and EXACT model number of your thermostat?
