5 Reasons Why Your Furnace Blows Cold Air

Be it a residential or a commercial heating system, all types of it are extremely complex. No matter how well-maintained or old a furnace is, it can still be subjected to heating failures.

In the case of furnaces blowing cold air, there are a few explanations. Here are the following:


Wrong Thermostat Setting

The most simple possible reason your furnace blows cold air is when your thermostat’s setting is incorrect. Make sure that your fan is set to the “auto” mode rather than the “on” mode. This will prevent continuous blowing of air when your furnace is recycling, resulting in cool air.

One thermostat problem that can also affect your furnace’s performance is its battery. While most modern thermostats don’t need batteries, there are still some that utilize a battery pack. If this is the case, make sure you regularly check and change its batteries.

Dirty Air Filters

If you can’t remember the last time you’ve changed your air filters, then it’s time to do so. One major factor that can affect your furnace’s heating performance is a dirty air filter. Dirty filters will impede proper airflow that could lead to overheating. So, be sure to change your filters at least once a month regularly.

Fuel Source Issues

Several types of furnaces utilize different fuel sources, such as oil, electricity, and natural gas. If your furnace is having issues with any of the fuel sources, your burner won’t turn on, resulting in cool air.

For instance, if your furnace runs on oil, regularly inspect if there is enough oil in the tank—this goes the same to other fuel sources.

Blown Out Pilot Light

Older types of furnaces or any other heating system with continuous pilot light could indicate that there’s something wrong with your system. When this happens, chances are there is an issue with your gas valve.

Some pilot light issues are best left to the professionals for safe and proper proceedings.

Burner Sensor Problems

Your furnace’s burners or flame sensors are susceptible to dust and dirt accumulation. If you fail to maintain them regularly, fuel won’t get through the system to be heated. Aside from dirty burners, wear and tear on these components can also affect your furnace’s heating power.
