The last thing anyone wants on a freezing cold day is to turn on their heating system, only to discover it is blowing out cold air. You may immediately panic and wonder why this is happening. There are actually many reasons why this could be, and some are less problematic than you might think.
You, therefore, don’t need to call a professional right away when your furnace is blowing out cold air. However, in the event, you try the following troubleshooting tips and it doesn’t seem to do the trick, Ambient Edge can take a look for you and see what all the trouble is about. Simply give us a call at (888) 240-8283 to schedule your service call.
Dirty Air Filter
Hands down, one of the most common reasons why a heating system may be blowing cold air is because it is suffering from a dirty air filter. A buildup of dirt can certainly impact whether air is able to reach the chamber that warms it up. And so, while the air is able to come through, it doesn’t come through the right channel, and it comes out cold. Changing the unit’s air filter should set the system back to normal.
You can also prevent this problem from happening again in the future by signing up for a preventative maintenance contract. With preventative maintenance, Ambient Edge keeps an eye on your heating system so you don’t have to, making the necessary cleanings and adjustments to keep it running in tip-top shape for the duration of its expected lifespan.
If you don’t live alone, then it’s possible someone else in the home adjusted the heating system’s thermostat, either accidentally or on purpose. For instance, the thermostat may be set to cool, or even “Fan,” so, of course, colder air is going to come out. This is particularly true if you have a touch thermostat, which is so easy to accidentally reset simply by bumping into it. Check your thermostat to ensure it is set to the right temperature.
Lack of Oil/Gas
When was the last time you had an oil or gas delivery? The problem may be that your heating system has run out of its designated fuel, and so it is unable to heat up the air that is coming through it. Most furnaces will also shut down for your safety, so if you run out of gas or oil it may not run at all. Be sure to check your supply before calling a professional.

Flame Sensor or Gas Valve Issue
If your furnace isn’t blowing out hot air, then there may be an issue with the flame sensor or gas valve.
If the issue is your flame sensor, you’ll notice that your furnace starts out doing the right thing, heating up the air, but suddenly the air will turn cold again. If your flame sensor is worn out or has a buildup of dirt and grime, this can cause your furnace to keep turning off and on again.
If the issue is your gas valve, you’ll know because the furnace’s pilot light will refuse to come on. The gas valve can become compromised if you haven’t had your unit serviced in a while, as this can cause dirt and buildup to cause the valve to stick. If your gas valve is the problem, you’ll have to call an HVAC technician to come in and take a look.
If you have a heating system that relies on gas, you may be suffering a lack of service due to disconnection. Double-check that your payments are up to date on your gas bill, as even automatic payments can suffer a technical glitch sometimes. There could even be a problem with your gas line, so it wouldn’t hurt to call the gas company, both to check on the status of your account and to send out a technician to come to your area and check the line.
