Common Reasons Your Furnace May Be Blowing Cold Air
Experiencing cold air blowing from your furnace can be concerning. Here are some common reasons this happens, along with potential home remedies and explanations of the equipment involved. However, if these issues persist, you might consider having a professional take a closer look.
Thermostat Issues:
Sometimes, the thermostat may be set to “cool” instead of “heat,” or it might be malfunctioning.Ensure your thermostat is set to “heat” and adjust the temperature to a few degrees higher than the current room temperature. If it still doesn’t work, it may be time to replace or repair your thermostat. Our furnace repair services include comprehensive thermostat diagnostics and replacements.
Home Solution: Check the thermostat settings. Ensure it’s set to “heat” and the desired temperature is higher than the current room temperature. If it’s an older model, consider replacing the batteries or upgrading to a more modern, programmable thermostat.
Tools Needed: A screwdriver (to access the thermostat) and new batteries or a replacement thermostat if needed.
Functionality: A thermostat regulates the temperature in your home by signaling the furnace to turn on or off. A malfunctioning thermostat can lead to improper heating.
Dirty Air Filters:
Clogged filters can restrict airflow, making it difficult for the furnace to operate efficiently.
If you haven’t changed your air filters recently, check them now. A dirty filter can significantly limit airflow. We recommend changing your filter every 1-3 months during heating season. If you’re unsure how to do this, we can help with a professional furnace
Home Solution: Check the air filter and replace it if it looks dirty or clogged. This is typically recommended every 1-3 months during the heating season.
Tools Needed: Replacement air filter. You might also need a vacuum or damp cloth to clean around the filter area.
Functionality: Air filters trap dust and debris, preventing them from entering the furnace. Clean filters ensure better airflow, improving efficiency and indoor air quality.
Pilot Light Problems:
If the pilot light is out or the electric ignition isn’t functioning, your furnace won’t heat.
If your furnace has a pilot light, ensure it’s lit. If it’s out, follow the manufacturer’s instructions to relight it. If the light won’t stay lit, there may be an issue with the thermocouple or gas supply. Our team is equipped to handle these repairs quickly and effectively.
Home Solution: For furnaces with a pilot light, carefully relight it according to the manufacturer’s instructions. If you have an electric ignition, check if the switch is turned on and look for any obvious issues.
Tools Needed: A long lighter or match (for pilot light) and possibly a multimeter to check electrical components.
Functionality: The pilot light is a small flame that ignites the gas in a furnace. If it goes out, the furnace won’t heat. Electric ignition systems perform a similar role, starting the furnace when heat is needed.
Ductwork Issues:
Leaks or blockages in the ductwork can prevent warm air from reaching your living spaces.
Check for visible signs of damage or blockages in your ductwork. If you suspect leaks, our duct sealing services can enhance your furnace’s efficiency by ensuring that warm air reaches its destination without losses.
Home Solution: Inspect visible ductwork for any signs of leaks or disconnections. You can use foil tape to seal small leaks temporarily.
Tools Needed: Foil tape, a flashlight for inspection, and possibly a duct cleaning brush.
Functionality: Ductwork distributes heated air throughout your home. Any obstructions can disrupt this airflow, leading to uneven heating and cold spots.
Furnace Size:
If your furnace is too small for your home, it may struggle to heat the space effectively.
If your furnace is undersized for your home, it may be time to consider an upgrade. We provide consultations on the best options for your heating needs, ensuring your space remains comfortable.
Home Solution: Monitor how the furnace performs. If it runs continuously without warming the space adequately, it may be undersized. In such cases, consulting with a professional for sizing recommendations is wise.
Tools Needed: None for this solution, but keeping a note of your heating needs may be helpful for future discussions.
Functionality: A properly sized furnace ensures efficient heating. If it’s too small, it can’t keep up with the demand, leading to cold air blowing.
Mechanical Failures:
Issues with the blower motor, limit switch, or other internal components can prevent proper operation.
If none of the above solutions resolve the issue, your furnace may have a mechanical problem. Our furnace repair services cover a wide range of issues, including repairs to the blower motor, limit switch, and more.
Home Solution: Listen for unusual noises or check for error codes if your furnace has a digital display. If you notice problems, it’s often best to stop using the furnace and contact a technician.
Tools Needed: A multimeter for checking electrical components, and possibly a user manual for troubleshooting guidance.
Functionality: The blower motor circulates air through the ducts, and the limit switch controls the furnace’s temperature. Malfunctions can lead to inefficient heating or safety hazards.
