3 Reasons Why Your Furnace Is Blowing Cold Air

There is nothing less frustrating than sitting inside on a winter day only to find that your furnace is blowing cold air. This can happen for a couple of reasons but it is usually safe to assume that cold air blowing from your furnace is indicative of a problem. Take a look at these 3 reasons why your furnace may be blowing cold air so you can call a certified HVAC technician to come and take a look at it and get you back to the level of comfort that you are used to. 

What Does Your Furnace Do?

Your furnace is the component of your HVAC system that is responsible for heating your home. It functions when some fuel source such as natural gas or oil is ignited via a pilot light. This ignition then heats the air in the burner, which travels through your ductwork and makes your home nice and warm. 

Reasons Why Your Furnace is Blowing Cold Air 

While your furnace can blow cold air for a multitude of reasons, here are the three most common that could indicate a problem. 

Your Pilot Light is Out 

Your pilot light may be the reason behind why your furnace is blowing cold air. Your pilot light provides the ignition source for the fuel in your furnace. If the pilot light is out, there is no source to ignite your fuel, leaving only cold air to be blown out. If you notice your pilot light is not lit, give your HVAC technician a call so that can identify the problem and have it fixed quickly.

Your Ductwork is Damaged 

If your ductwork is damaged, hot air can be leaking out and cold air could be rushing in through holes or cracks. This can be a simple fix. All you need to do is get duct sealant and ensure that your ductwork is air tight. Make sure you call the experts at Ellis Air Conditioning and Heating so they can perform a thorough inspection of your ductwork. 

You Have a Low Gas Supply

Most furnaces are programmed to deactivate if there is an insufficient gas supply. If your furnace is blowing cold air, then you may have low gas. If you suspect this may be the case, you should have a technician come and inspect your gas supply.

Before you do anything to your HVAC system, you should always have a trained professional help you so that you can avoid making an expensive mistake. Make sure your HVAC providers are experienced, knowledgeable, and eager to help you with any of your HVAC problems.
