How Do You Handle It If Your Furnace Is Blowing Out Cold Air?

October 26, 2021

Your furnace should provide you with plenty of heated air to keep your Neptune City home warm. When you have a furnace blowing out cold air, it’s important to figure out why this is happening and what to do about it. Keep the following tips in mind if you have this heating problem.

Check the Filter

Your HVAC filter should be clean in order for your furnace to work properly. A filter that’s covered in dust, pet dander, and other debris can result in your furnace blowing out cold air instead of heated air due to airflow problems. Replacing a dirty air filter with a clean one should stop this from happening. Remember to change your air filter regularly to prevent this problem from occurring again.

Check Your Thermostat

Problems with your thermostat could result in your furnace blowing out cold air. You should first check the setting on your thermostat. If the fan is running continuously, change the setting to “Auto” rather than “On.” When the thermostat is set to “On,” cold air blows through your vents. Changing it to the “Auto” setting means it should run in heat cycles. If you’re experiencing any other problems with your thermostat, this can also cause your furnace to blow cold air only. Replacing a broken thermostat or having it repaired should fix this problem.

Check the Pilot Light

If you have a gas furnace, check the pilot light. If the light is out, your furnace will only blow cold air through your vents. If you’re not sure how to safely light the pilot again, have an HVAC professional do so for you.

Check the Control Panel

Problems with your control panel can lead to your furnace blowing out cold air only. You can try resetting the panel to see if this fixes the problem. If not, you should have HVAC technicians inspect your furnace and make repairs as needed.
