When the weather starts cooling down, homeowners count on their furnaces to deliver steady warmth. So when that comforting heat turns into a blast of cold air, it can feel both frustrating and concerning. Understanding why this happens helps determine whether you need a quick adjustment or professional help from Spokane furnace repair experts.
Common Reasons Your Furnace Blows Cold Air
Cold air from your furnace often signals a problem that needs attention before temperatures drop further. Typical causes often involve thermostat malfunctions, limited airflow, or problems within the furnace’s internal components.
1. Incorrect Thermostat Settings
Sometimes the issue is as simple as your thermostat being set to “on” instead of “auto.” In this mode, the fan keeps blowing even when the furnace isn’t producing heat, which sends cool air through the vents. Changing it to “auto” ensures the fan runs only when warm air is available.
2. Clogged Air Filters
A clogged filter blocks proper airflow, making the furnace strain to circulate warm air efficiently. When air can’t move freely, it might feel cool coming from your vents. Regularly checking and replacing filters keeps your system efficient and prevents strain that could lead to bigger repairs later.
3. Pilot Light or Ignition Issues
For gas furnaces, a weak or extinguished pilot light is a frequent reason for cold air. Electric ignition systems can also fail due to sensor or wiring problems. These components should always be inspected and repaired by professionals to ensure safety and reliability.
4. Overheating Safety Shutoff
If the furnace overheats, safety mechanisms automatically shut off the burners while keeping the fan running to cool the system. This safety response may cause blasts of cold air until the unit resets. Overheating often results from restricted airflow or mechanical malfunction, both of which require attention.
When to Call a Professional
Some issues can be corrected easily, like adjusting a thermostat setting or replacing an air filter. However, persistent cold air usually points to deeper mechanical or electrical problems that need skilled attention. Pace Plumbing’s technicians have the training to safely inspect, diagnose, and restore heating performance before the situation worsens.
