If you live in a colder climate, then your furnace is crucial to your family’s comfort, which is why it can be so frightening to turn on your furnace on a freezing morning, only to discover that instead of warming your home, you are only getting freezing air out of your vents.
There are a few proper reasons why your furnace could be blowing freezing air.
Here are some reasons why your furnace may be blowing freezing air, plus what you can do about them. If your pilot light is out, your furnace may be blowing freezing air. If your pilot light goes out, then your furnace has no way to provide heat to your home. Some heating systems have pilot lights that can be lit by the user, while other pilot lights need to be lit by an Heating plus A/C professional. Check out the side of your Heating plus A/C plan for a diagram on how to find your pilot light. If you have an airflow problem, your furnace may be blowing freezing air. An airflow concern can be caused by leaks or gaps in your air duct. Over time, the metal in your air duct will expand plus contract with the heat, plus it can cause gaps in your air duct, resulting in a loss of air flow. Having your air duct checked by an Heating plus A/C professional is the best way to ensure that your ducts are in proper working order. Airflow troubles can also be caused by a plugged air filter. Your cooling system filter works to unattach dirt, dust, plus other debris out of the air in your home, plus can become plugged over time. Most Heating plus A/C professionals recommend increasing your air filter every 30 to 60 days, especially if you have pets.
