Why Is My Furnace Blowing Cold Air?

You rely on your furnace to heat your home, especially in the depths of winter when the temperatures in Indiana can drop well below freezing. This is why there are few things more frustrating–or more uncomfortable–than a furnace that is blowing cold air. If your furnace is blowing cold air, it’s important to troubleshoot the issue quickly and call a repair professional if you can’t fix the problem on your own. At Naughton Mechanical LLC, we are here to help. Call us directly to learn how.

Common Reasons Why Your Furnace Might Be Blowing Cold Air

There are a few common reasons why your furnace might be blowing cold air. Check the following, and then call our team for trusted repair services if you need more help–

• Your thermostat is broken or needs new batteries. It sounds obvious, but you’d be surprised how many times the problem isn’t with the furnace but with the thermostat. If your thermostat is old, it may be time to replace it. Start by replacing the batteries and see if that doesn’t do the trick.
• Your air filter needs to be replaced. If your air filter is especially dirty, the movement of air through the filter will be impeded. This can result in the temperature within the furnace rising, which will trigger the limit switch, which shuts down heating so the furnace doesn’t overheat. Replacing your filter is an easy and inexpensive fix.
• The pilot light is out. This is a common problem and one of the first things that you should check if your furnace is blowing cool air. To fix this, turn off the power to your furnace first. Then, turn the pilot light to “OFF” and wait for 10-20 minutes for any gas to clear the area. Then, switch it back to “PILOT,” light the pilot light, and then turn the setting back to “ON.” Finally, turn the power back on to the furnace.
• Damaged ducts. If it’s especially cool outside and your ducts are damaged and leaking, that hot air will escape, and in its place, cold air will enter. This means that by the time the air reaches the room you’re in, it could feel quite brisk.
