The last thing that you want to happen in Thornton, Colorado is to wake up on a cold Saturday morning and find that your furnace is blowing cold air. Find out a few reasons why your furnace is blowing cold air from Cozy Comfort HVAC in Thornton, Colorado.

Why is Your Furnace Blowing Cold Air?

There are many reasons why your furnace could be blowing cold air. Below are a few quick ways to troubleshoot the issue before you contact an HVAC professional. 
  1. Air Filter: If you skip replacing your air filter your furnace could blow cold air. If the filter is clogged you are definitely blocking free airflow. A good rule of thumb is to replace your furnace filter every 30 days. Set a reminder or event on your cell phone and your phone will never let you forget another furnace replacement.
  2. Check Your Thermostat: Check your thermostat and ensure that the heat is on. Kids...especially teenagers get much hotter than adults and when you're at work they could flip the furnace off or even worse switch on the AC or the fan to blow cold air.   Regardless of whether the unit is heating the air or not, the fan on a heater will keep on blowing as long as the thermostat is set to ON.  So check your thermostat setting. Ensure it is not set to ON. But if it is, you only need to flip the switch back to AUTO. Once you’ve restored the correct setting, your furnace should blow warm air.
  3.  Pilot Light or Ignition Issue: If your gas furnace seems incapable of blowing hot air, the problem could be with the ignition system. In such a case, your heater is not lighting the fuel, as a result of which it cannot heat your home. Confirm whether the pilot light is out.
