4 Reasons Air Isn’t Flowing From Your Furnace

It’s a freezing winter night in St. Louis, MO, and you’ve cranked your furnace up to stay warm. An hour later, you’re still shivering, and nothing is coming out when you check your air vents. What gives? If your furnace isn’t blowing hot air when you need it to, there could be some problems you need to address. In this article, we’ll discuss why your furnace isn’t blowing any air and what you should do about it.

1. Dirty Air Filters

A common reason your furnace isn’t blowing any air could be dirty air filters. When your air filters are covered in dust and dirt, the heated air can’t get through to warm your home. This can also make your HVAC system inefficient, making your energy bills spike. You can change your air filters to fix this problem, or you can schedule an appointment with a local HVAC contractor who can change them for you. Make sure you have the right air filter size for your HVAC system.

2. An Unlit Pilot Light

If your furnace’s pilot light isn’t lit, the furnace won’t turn on or blow any air. Go to your furnace, remove the front panel, and check whether you can see a pilot light. If you can’t see the blue flame, there’s a problem. If you see a flame with a different color, you need to reach out to an HVAC company.

You can relight your pilot light by yourself using the instructions on your furnace or in the manual. If you feel uncomfortable relighting it yourself, contact a knowledgeable HVAC technician for help.

3. Low Gas Supply

A low fuel supply could be one reason you have no air flowing from your furnace. If you have a gas furnace, it needs a constant supply of fuel to run. If it runs low, it may turn off automatically. A qualified HVAC technician can determine if you’re low on fuel and add more to your furnace.

4. A Damaged Blower Fan

Your furnace’s blower fan pushes the heated air throughout your home. If it’s not working, you won’t feel air coming out of your vents, even if your furnace is heating properly. Sometimes blower fans stop working due to motor issues, or sometimes it can be caused by the furnace’s circuit breaker. If you put your furnace in fan-only mode and still don’t feel air coming from your vents, reach out to an HVAC technician who can repair your blower fan.
