7 Reasons Why Your Furnace is Blowing Cold Air & How to Fix It

When you start to run your furnace and notice it is blowing cold air, this could mean a variety of things including gas supply, filter issues, flame detector or just an issue internally. You might think that this means your furnace is broken, but determining why it is blowing cold air will be the first step in how to fix it. Here are 7 common reasons why your furnace is blowing cold air and how to fix it: 

Pilot Light is Damaged 

The pilot lights on some furnaces, lights the burners to establish heat. When the light is damaged or blocked, it cannot heat up the burners, thus blowing cold air through your home. The way to fix this is to first locate the pilot light. Once you locate it, you can repair it accordingly. You may also need to reset the pilot light, which is located on the furnace, near the light. If you cannot fix it, you may need a furnace repair or maintenance service to come out and take a look. 

Flame Detector has Dirt or Grime 

On gas furnaces, they rely on flame detectors to ensure the system is heating completely. If the flame detector has dirt, it can cause the system to not stay warm or cold blow air. This can simply be fixed by removing any dirt or grime on the flame detectors. 

Air Filter is Clogged 

Just like with air conditioners, the filter is extremely important. When the filter gets clogged with dirt, debris and pet hair, it can restrict the airflow. You may have a clogged filter if you experience overheating cycles and long heating cycles that just blow cool air. To fix this issue, it is recommended to have a free air quality test and to change the air filter once a month.  

Low Gas Supply 

If you have a gas furnace, you may have low gas supply. A furnace pulls gas in order to heat up. When it does not receive the correct amount of gas, the system automatically deactivates. However, if this seems to be the issue, there is no effective way to fix this on your own. The best thing to do is to call the HVAC experts. 

Ductwork Damage

Ductwork is a collection of pipes and passages that deliver the air all throughout the home. If there are cracks, holes or damages in the ductwork, it can cause the air to not reach the desired room or cause the air to leak out. By doing a ductwork check, you can locate if there are any blockages and you can seal them. This will allow the air to flow freely throughout the home. 

Thermostat Issues 

Most people have their thermostat on auto, but this could be the reason for the cold air. When the thermostat is set on auto, it will constantly blow air, regardless if it is warm. Set the thermostat to the desired setting and this will slow down the system to heat up, then blow the warm air out. It is also a good idea to upgrade to a Lennox smart thermostat. It provides an accurate reading of heat in your home and allows you to access the dials via wifi. 

Condensate Lines are Blocked 

Condensate lines are designed to remove excess moisture from the system. When these lines are blocked, it can cause the furnace to deactivate and not heat up, resulting in cold air. When you see the condensate lines, make sure that there are no blockages within the line. 

Bottom Line

The bottom line is that if your furnace does not work properly, you should schedule an expert at The Chill Brothers to ensure your system is accurate. Call us today: (832) 478-7777
