Why is My Furnace Blowing Cold Air? Bartlett Heating and Air Has the Answer

Did you wake up or come home to your furnace blowing cold air? If your furnace has cold air coming out and then it turns to warm then you are fine but if the cold is constant then it is an issue. Your furnace can be blowing cold air for various reasons and means it needs service. It could be something simple and easy to fix or it could require a tech like Bartlett Heating and Air to fix it. Here are some of the reasons your furnace may be blowing cold. Check your thermostat and make sure it is on AUTO not ON. When it is on the ON position then it will blow constantly even when the furnace doesn’t have warm air to blow out. Turning the thermostat on AUTO will only have it blow when the air is warm. Your furnace may have overheated so now it will blow cold air. There is a safety device in your furnace called the limit switch that protects the furnace by shutting off the burners. The cold air will continue to blow because it needs to cool the furnace down. This can be caused by a dirty filter so make sure you check that the filter is not clogged. If changing your filter does not solve the issue then you need to call Bartlett Heating and Air right away to fix it. Another possible cause of blowing cold air is your pilot light being out. You could have a dirty flame sensor that is causing the furnace to blow cold air. These are some of the reasons your furnace may be blowing cold. If your furnace continues to blow cold air, call Bartlett Heating and Air!
