    Heater not blowing hot air
    My heating unit is about 14 years old. Earlier in the week the weather was 70 degrees, today it's down to 26 degrees. My heat is on however it's blowing cool air as I have the thermostat set around 66 degrees. When the auxiliary heat kicks in, it gets warm. Also, it seems to run constantly. I don't remember this happening before when it was this cold. Once the house reached a certain temperature, the unit would kick off. So far it's ran all night and all morning. Please help! I don't want to call someone out and get ripped off. Thank you!

    Did the problem start when you installed the new thermostat?

    What brand and model number of thermostat?

    I don't have a new thermostat. The model is American Standard. I was saying I usually keep it set at 66 degrees. However, this time it seems to be blowing cool air and constantly running. When the axiliary heat kicks on it's warm air. It's like the heating and cooling unit is trying to get the house to a certain temperature but it can't.

    Something is failing or has failed on your outside heat pump unit. You might check the circuit breakers on the inside of the home and the disconnect outside near the unit.

    Also if the temperature out side is cold enough the heat pump capacity will diminish.

    What would checking the circuit breakers do? Thanks for your help!

    If the breaker has tripped to the off position the outside unit will not run.

    It would tell you if the power(electric) is on to the heat pump,

    If your heatpump is not working you can set your thermostat to emergency heat. This will lock your heatpump out and you can heat with your electric heat strips in the fan coil until you get your heatpump back up and running. Yes it will use more electricity to run but your heatpump is not working the way it should and they are coming on any way.
