Greetings from Tassio Temperature Control! San Fernando Valley winter is in full swing, and there’s nothing worse than discovering that your heater is blowing cold air when you’re in need of a cozy, warm environment. Before you start piling on extra layers, let’s explore some common reasons why your heater may not be doing its job.
Why is My Furnace Not Blowing Hot Air
There are many reasons your furnace may not be blowing hot air; from power supply issues to airflow interruptions many aspects can affect the health of your furnace. We will explore issues in both gas and electric heaters to explain why furnaces may not blow hot air.
Verify Your Power Supply
A lack of hot air could be as simple as a tripped circuit breaker or a blown fuse. Check your circuit breaker or fuse box to make sure your heater is getting the power it needs.
Check the Pilot Light/Ignition Issues
For gas heaters, a malfunctioning pilot light or ignition system can be the culprit. If you’re comfortable doing so, check the pilot light to ensure it’s lit. If it’s an electronic ignition system, there may be an issue with the ignition itself.
Is Your Gas Supply On
Ensure that the gas supply to your heater is turned on. Check for any issues with the gas line that could be preventing proper fuel flow.
Dirty or clogged air filters can restrict airflow, reducing your heating system’s efficiency. Regularly check and replace air filters to maintain optimal performance.
Your Thermocouple is Broken
If you have a gas heater, a faulty thermocouple can prevent the pilot light from staying lit, leading to cold air blowing through your vents.
Replace or Recalibrate Thermostat
A malfunctioning thermostat may not accurately sense the temperature, resulting in incorrect signals sent to the heating system. Consider replacing or recalibrating the thermostat if needed.
Inspect the ductwork for blockages or leaks. Damaged or poorly connected ducts can lead to heat loss, causing your system to blow cold air.
Problems with Heating Element/Heat Exchanger
For electric heaters or furnaces, malfunctioning heating elements or heat exchangers can result in cold air circulation. Regular maintenance can help prevent these issues.

Regular maintenance and attention to these common issues can ensure your heating system continues to provide a cozy environment to your San Fernando Valley home.
