When winter arrives in Springfield, IL, your furnace becomes one of the most important systems in your home. So, when you switch on the heat only to feel cold air blowing from the vents, it’s more than just an inconvenience; it’s a disruption to your comfort and a sign that something could be wrong. At Bormida Heating & Cooling, we understand how frustrating this issue can be. With over 14 years of experience in HVAC repair and maintenance, our certified technicians have helped countless homeowners restore warmth and peace of mind during the coldest months. If your furnace is blowing cold air, there are several potential causes. Here are five common reasons and how our experts can help resolve them.
Thermostat Issues
A common and often overlooked culprit is the thermostat. If it’s not set correctly or is malfunctioning, your furnace may not receive the right instructions to produce warm air. For instance, if your thermostat is set to “fan” instead of “auto,” it will continuously blow air even when the furnace isn’t actively heating it, resulting in a stream of cool air. Alternatively, a faulty thermostat may fail to signal the furnace to generate heat at all.
Resolution:
Our HVAC professionals can assess your thermostat settings, recalibrate or replace the unit if needed, and ensure it communicates properly with your furnace. In some cases, upgrading to a programmable or smart thermostat can offer better control and efficiency for your home heating system.
Dirty or Clogged Air Filters
A dirty air filter can restrict airflow, causing the furnace to overheat. When this happens, a built-in safety mechanism may shut off the burners, preventing the system from producing heat but continuing to blow air, resulting in a cold breeze rather than warm comfort.
Resolution:
Routine maintenance, including changing your air filter every 1–3 months, can prevent clogged air filters. If your furnace is already blowing cold air, Bormida Heating & Cooling technicians can inspect and replace the filter, reset the system, and check for any further damage caused by overheating.
Pilot Light or Ignition Failure
If you have an older gas furnace, a blown-out pilot light or ignition issue can keep the system from heating air. Without a consistent flame to ignite the burners, your furnace can’t warm your home, and cold air continues to circulate through the vents.
Resolution:
Our certified technicians will safely inspect your furnace’s ignition system or pilot light. If it’s out or showing signs of damage, such as discoloration or irregular flame, our team can clean the components, relight the pilot, or replace a faulty ignition sensor as needed. We will carry out any necessary furnace repairs and ensure your system is operating safely and efficiently before completing any service.
Leaky or Disconnected Ductwork
In some cases, your furnace might produce warm air, but it’s not making it into your living spaces. This can happen if there are leaks, holes, or disconnected segments in your ductwork. Cold air from unconditioned areas like attics or crawl spaces can mix with the heated air or replace it entirely.
Resolution:
The professionals at Bormida Heating & Cooling offer comprehensive ductwork inspections to identify leaks or damage. We’ll seal or repair any problem areas to restore proper airflow and improve the efficiency of your entire heating system. This not only ensures comfort but also lowers your energy bills.
Lack of Routine Maintenance
Like any mechanical system, your furnace needs regular maintenance to operate at its best. Without it, wear and tear can build up over time, leading to issues such as restricted airflow, inefficient heating, or malfunctioning components—all of which may result in the unit blowing cold air.
Resolution:
Our team provides professional maintenance services that include a full system inspection, cleaning, and tune-up. We catch small problems before they become expensive repairs and help extend the life of your furnace. Enrolling in a regular maintenance plan with Bormida Heating & Cooling ensures that your system is always running at peak performance.
