Why Is Your Furnace Blowing Cold Air?

You expect your furnace to keep you warm and comfortable throughout the winter months, so it can be unsettling if your furnace is blowing cold air. 

Common Reasons Your Furnace Is Blowing Cold Air

There are several reasons your furnace may be blowing cold air, some are very simple to fix, and others may indicate serious underlying issues.

The Fan Is Set to “On” Mode Instead of “Auto” Mode

When your furnace fan is in “on” mode, it is blowing air continuously all day, even when the furnace is not generating heat. If this is the case, it may feel like cold air is coming out. Switching the setting to “auto” means that the only air blowing out of your furnace will be warm air.

The Pilot Light Is Out

If you have a gas-powered furnace, your system will not be able to produce warm air without the pilot light. It is natural for the light to go out from time to time, and it just needs to be re-lit. It is best to call in a professional for this task, as it can be a dangerous job if not done correctly.

Damage to Ductwork

The hot air produced by your furnace will only make it to where it’s supposed to go if your ducts are sealed. If you have damaged ductwork, the warm air can escape before it ever reaches the vent. Damage to ductwork needs to be addressed by a professional who can detect and repair the issue.

Does Cold Air Mean It’s Time for a New Furnace?

Cold air does not necessarily mean your furnace is bad and needs to be replaced. In fact, in most cases, the underlying cause for cold air can be repaired by an HVAC technician

However, there are always exceptions, particularly if you have an old furnace. Sometimes repairs make less sense than replacing the entire unit. 

How to Get Your Furnace to Blow Hot Air

If your furnace is not blowing hot air, there are a couple of minor troubleshooting things you can try, such as allowing your furnace time to heat up and adjusting the settings. Beyond this, it is best to call in a professional. 

DIY attempts to repair your furnace could end up causing more harm than good. An HVAC technician will be able to quickly identify why your furnace is not blowing hot air and make the necessary repairs.
