Why Is Your Furnace Blowing Cold Air?

Why Is Your Furnace Blowing Cold Air?

November 7, 2017

A furnace that blows cold air is the last thing you want when the weather gets cold in Apex, NC. If it happens more than once or lasts longer than one or two minutes, it’s time to take action. Heater problems like this can pose a dangerous fire hazard to you and your family. Fortunately, while that blast of cold air indicates a repair is in order, many issues can be resolved quickly and affordable.

Simple Problems with Easy Fixes

To diagnose a heater that’s blowing cold air, start with the components you can easily access:

  • Check the thermostat to make sure that the fan setting hasn’t been switched from “on” to “auto.” If the thermostat is powered by batteries, replacing them might do the trick.
  • Examine the air filter for signs of dirt. A clogged or dirty filter restricts airflow, which can cause the heater to shut down to protect it from overheating.
  • If your heater has a continuous pilot light, verify that it’s still burning. If it’s out, but you don’t feel comfortable igniting it, call in a reputable technician.

Note: A pilot that won’t stay lighted doesn’t always indicate a serious problem. The culprit may be the thermocouple, the component that controls burner ignition. An HVAC technician can replace this quickly and safely.

Repair or Replace?

Blower components include safety devices that monitor the temperature of the heater. When something goes wrong, the sensors turn off the burners to safeguard you against a fire. If an inspection reveals a major problem like a cracked heat exchanger, replacing the system might be a better option. Other factors to consider include the age of the system and its overall energy efficiency.
