Why Is My Furnace Blowing Cold Air?

A furnace breakdown can be a real nightmare in the dead of winter. The last thing you want is for your heating system to blow cold air when the temperature is in the single digits. After all, a working furnace is critically important to your comfort and your well-being!

There are a few issues that could cause your furnace to blow out cold air, but how do you know which one you’re facing? Thankfully, our HVAC specialists at Air Experts can help you figure that out, and can help you get your furnace functioning normally again as soon as possible.

Reasons Your Furnace May Be Blowing Cool Air

The Thermostat Is Set Incorrectly

Cold air can be emitted by a furnace for a variety of reasons. Most of these problems require the expertise of a seasoned HVAC professional. However, there is one thing you should check on your own before calling Air Experts: whether the thermostat is simply set to a low temperature. Perhaps you accidentally bumped the “cool” button, or maybe a family member or co-worker likes it cool even during those chilly winter months. It may sound silly, but we see it more often than you’d think! Be sure to check the thermostat setting before taking any other action. Also, if you have recently installed a thermostat, it might not be compatible with your current heating system. Or, maybe the battery is low and needs to be replaced.

The Valve Is Dirty

Your furnace’s cool air could also be the result of a valve issue. Malfunctioning gas valves can prevent the pilot light from lighting and remaining lit. Maybe the system hasn’t been cleaned out in years and a valve is jammed due to a buildup of dirt.

The Pilot Light Is Out

Homeowners who have an old furnace should check the pilot light to see if it is lit. If it is extinguished, the furnace will not generate warm air. A strong air gust can easily extinguish a continuous pilot light. Perhaps the oil filter is clogged on your oil-fired furnace. Anything from stray debris to a buildup of dirt can jam the oil filter and forcing the system to generate cool air. Replacing the filter is not a clean and easy job so don’t hesitate to reach out to the professionals here at Air Experts Heating & Cooling.

The Furnace Overheated

It is also possible that your furnace overheated. A failure to replace the furnace air filter has the potential to alter air flow to the point that the furnace overheats. The burners of an overheated furnace will shut down. Or, maybe the electronic ignition no longer functions as designed. A slight adjustment performed by an Air Experts furnace expert might be necessary. If a part has completely failed, it must be replaced.
