Why Is My Furnace Blowing Cold Air?
Although you may have recently had a furnace installed, it doesn’t necessarily mean that you wouldn’t have any furnace problems to deal with. You might be able to fix the minor issues yourself. However, you must know when to call in a professional for the job. Their expert solutions can help you avoid spending an unnecessary amount of time in cold indoor spaces.
We at QUINNAIR Heating & Air Conditioning are one of the frontrunners in this industry, and provide our clients with high-quality and reliable services. Here are a few of the most common reasons why your furnace is blowing cold. We also give you some tips on troubleshooting cold air issues:
Common Reasons for Cold Air from the Furnace
Incorrect Thermostat Setting
Someone may likely have turned the thermostat setting from AUTO to ON. This causes the fan to run non-stop without providing any heat. All you have to do is turn the setting back to AUTO, and it will start heating again.
Issues with the Computerized Controls
Consider resting the entire system if you have one of those newer furnaces that have an electronic control panel. Hold on for a couple of minutes and then restart it. It’s similar to when you reboot your computer to fix a software glitch. Consider calling in a professional for troubleshooting cold air issues, if they persist.
Issues with the Valve
A faulty gas valve can mean the pilot light won’t come on. Sometimes, the valve gets stuck because of dirt and debris accumulation. Consider getting your system cleaned and have it inspected by a professional.
No Oil in the Tank
In case you have an oil-fired furnace and the system isn’t heating, chances are it’s out of fuel. When the burners don’t light, they fail to produce heat, which means the blower continually circulates cold air. Refill the fuel tank and try to restart the system; it should start blowing hot air.
Blocked Oil Filter
Similar to a gas-fired system or an air filter system, dirt and debris can result in blockages in your oil-fired furnace. A clogged filter causes problems with the ignition. You can clean or even replace the filter yourself; however, it does get messy. Consider leaving such furnace problems and service in the hands of skilled professionals.
Furnace Is Over-Heating
The most common cause of over-heating is an obsolete air filter. This compromised airflow results in overheating, causes the burner to shut down, and the system blows cold air. Consider having the air filter replaced, and restart your furnace.
No Pilot Light
The pilot light on your furnace may have turned off if you have an older model. The reason for this might be a gust of air from someone working with air pressure tools, near it. You can relight it if you know how to. If not, call in a professional to fix the problem.
