5 Reasons Why Your Furnace Is Blowing Cold Air

Heater Repair in Lincoln, NE

During winter, we all appreciate a pleasant, warm space. Imagine the disappointment when you find out your furnace is blowing cold air. Here are the five common reasons why this is happening.

1. Thermostat Is Set Incorrectly

When you notice your furnace is blowing cold air, you should check the thermostat setting first. Sometimes your thermostat fan may have been switched from AUTO to ON, causing the fan to run continuously without producing heat. In this case, simply change the setting back to AUTO, and your furnace will start heating the air.

2. Low Battery

In case you’ve had your furnace for a while and have never changed the battery, it might be blowing cold air because the battery is low. In this case, we recommend that you change the battery then restart your furnace.

3. Furnace May Have Run Out of Fuel

If your furnace is oil-fired and your fuel runs out, the blower will continue circulating cold air even if the burners don’t produce heat. Check the tank to rule out this possibility. We recommend that you call us if the oil has run out, and we will fix that for you.

4. Furnace May Have Overheated

If you have been using your furnace for a while without changing the filter, the airflow may have been compromised, overheating the furnace and causing the burner to shut down. Changing the filter can resolve this.

5. Incompatible Thermostat

If you recently installed your thermostat yourself, you may have chosen one that’s incompatible with your current heating system, and you may need to call in a professional to check that.
