Why is my furnace blowing cold air?

When the weather gets cold outside, there is nothing more frustrating than going to turn on your furnace, only to be unpleasantly surprised by the sensation of cold air coming from your vents.

So many of us rely on our heaters to stay comfortable in our homes during the winter, and cold air blowing during this time can be devastating. Here are some reasons why your furnace may be blowing cold air, and what you can do about it. The first thing that may be causing your furnace to blow cold air is a clogged air filter. Over time, your air filter can become oversaturated with dirt and debris, which can make it difficult or even impossible for your HVAC system to properly circulate the air throughout your home, and this can possibly cause your furnace to overheat, and safety mechanisms will cause them to turn off. Most HVAC professionals recommend changing your air filter every 30-60 days, especially if you have pets. Another reason why your furnace may be blowing cold air is because your pilot light may be out. Check with your owners manual before attempting to re-light a pilot light, but occasionally, these flames can be put out by buildup in your gas lines, or swift changes in air pressure. The best way to make sure that your furnace won’t blow cold air when you need it warm is to have regularly scheduled maintenance and inspection of your HVAC system by a licensed professional. Your HVAC provider will be able to identify problems before they arise, ensuring that you have a hot furnace all winter long.
