How to Fix Your Furnace Blowing Cold Air: 7 Causes

Advantages of HVAC Preventive Maintenance

If you have a furnace blowing cold air, the problem may be that your ductwork is clogged or something is wrong with your thermostat. If you notice that your furnace is blowing cold air in the winter or hot air in the summer, there are a few things you can try to fix by contacting a heating service in Magnolia, TX.

What Causes My Furnace To Stop Blowing Warm Air? How To Prevent It?

  • The Pilot Light Is Damaged: Pilot lights are responsible for igniting the main burner and ensuring that your furnace has a constant supply of gas—so if it’s damaged, you won’t be able to heat your home. To test if this is the problem, turn off the thermostat and turn on the furnace. If there’s a pilot light but no heat, it’s likely that the pilot light is damaged.
    To Fix This Issue:
    1. Check whether any wires leading to the pilot light have been disconnected or damaged.
    2. If disconnected or damaged, reconnect them and test your furnace again.
    3. If everything seems fine, but there isn’t any heat from your furnace, call a heating service in Magnolia, TX, for help.

  • Flame Detectors Have Dirt Or Dust: The flame detector is another important component of your furnace because it prevents gas from being released into your home. If dirt or dust builds up on this component, it will prevent it from working properly. To clean the flame detector, remove it from your furnace and gently wipe any dirt or grime off its surface with a damp cloth.
  • The Air Filter Is Clogged: The air filter is likely clogged if your furnace is not blowing warm air. To solve this, you need to clean or replace the filter. First, remove the cover to expose the air filter. You can vacuum if the filter is dirty but not completely clogged. If there are large particles of debris in the filter, you’ll need to purchase and install a replacement filter.
  • Low Gas Supply: If your furnace is blowing cold air, it could be because your gas supply is low. This can happen for various reasons: maybe someone turned off your heat without telling anyone else in the house or accidentally turned off their gas. Regardless of what caused the problem, you’ll need to call the heating repair the Woodlands, to repair it before you can turn on your heat again.
  • Thermostat Issues: The thermostat that controls your furnace might be set at too low of a temperature or broken altogether. To avoid this issue, ensure every room in your home has a separate thermostat so you can control each room temperature independently.
