Reasons Why Your Furnace Is Blowing Cold Air

We know that winter in the Metro East can be brutal, and the last thing any homeowner wants is to find their furnace blowing cool air despite the temperature rating on their home’s thermometer. Thankfully, C&K Heating & Cooling in the Metro East area has over 25 years of experience in the industry to help! There are several reasons why your furnace is not running properly. For professional help, call our friendly staff today and schedule an appointment. We guarantee that your furnace will be fixed in no time! Keep reading below to learn about the most common reasons as to why your furnace is blowing cold air.

You May Have an Issue with Your Pilot Light

If you own a gas furnace, one of the most common issues, when cool air is blowing throughout your home, stems from the pilot light. A pilot light is a small blue glowing flame that is used to ignite the burners within your furnace. If there is an issue with the pilot light, a color change, or it has gone out completely, the energy needed to heat your home cannot be created. To check if your pilot light has gone out, review your furnace’s instructions manual and try relighting the flame with a standard lighter. If you try this and the flame still burns out, we recommend immediately calling our technicians at C&K Heating & Cooling in the Metro East area for expert furnace repair services.

Your Air Filter May Need to be Changed

When was the last time you changed the air filter on your furnace? If you can’t seem to remember, it may be overdue! Oftentimes when homeowners leave their furnace filters unchanged, dust and debris buildup are collected from the ventilation system traveling throughout your home. Eventually, all of those dust particles end up in your furnace’s air filter and clogging it over time if not taken care of regularly. If your air filter desperately needs to be replaced, the lack of ventilation can restrict

the airflow throughout your home, forcing your vents to blow cold instead of hot air. Try inspecting your furnace’s air filter! If you are unsure of how to replace the filter yourself, give our experienced technicians a call C&K Heating & Cooling at (618) 537-8888 in the Metro East area. We are always happy to help!

Your Furnace Could Be Overheated

Another common issue as to why your furnace could be blowing cold air is that your system is overheated. Over time with excessive use, your furnace’s heat exchanger can begin to fail if you do not regularly clean your air filter, or there is a manufacturing issue with the part. Once your heat exchanger fails, there is no way for your furnace to accurately disperse heat throughout your home, making it continuously run cold air through your air ducts. If your furnace has been running too long with too dirty of an air filter, the entire system begins to overheat, causing cool air to run throughout your home. Contact C&K Heating & Cooling today for expert HVAC repair and maintenance services in the Metro East area.

You Could Have Issues with Your Air Ducts

Your air ducts are what push the heat from your furnace throughout your own, keeping it warm and cozy all winter long. If there is a hole or leak in your air duct system, the heat flowing in from your furnace will not be able to travel within your ducts, pushing cool air out of your vents and into your home. Thankfully, this means that your furnace is working great, however, repair issues will need to be made by a professional technician to get your ventilation system working again. C&K Heating & Cooling has 
been one of the leading HVAC repair companies in the Metro East area for over 25 years. Contact us today and schedule an appointment to have your furnace and air ducts inspected and repaired at an affordable rate.
