Routine furnace maintenance is key when it comes to reducing the risk of a breakdown and staying warm throughout the winter season. But, even with proper care, problems can still occur. If your unit is blowing cold air, it’s important to address the issue right away to determine whether you need a professional furnace repair. Below are a few helpful steps to try first.

How to Troubleshoot Your Furnace

1. Inspect the Thermostat

When the furnace is blowing cold air, the thermostat is the first component to inspect. If the fan setting is turned on, your system will continue to emit cool air from the vents even if the unit isn’t currently in use. To fix this problem, switch the fan setting to auto mode.

2. Change the Air Filter

If you don’t change the air filters routinely, they will collect the dust and debris circulating throughout your home. Over time, this restricts the airflow and forces the furnace to overheat and turn off. You can fix this problem by changing the component when it gets dirty, or at least once a month.

3. Check the Pilot Light

Cold air may also indicate a problem with the unit’s ignition system. Turn on the pilot light. If it doesn’t stay lit, contact a furnace repair professional to replace the thermocouple, which detects whether the component is on.
