Why is My Heater Blowing Cold Air?
On a chilly day, you look forward to the warmth provided by your heating system. It can be startling to encounter cold air coming from your vents. You can take some preliminary steps to evaluate the situation before you contact your heating professional to come out and answer the question, “Why is my heater blowing cold air?”
Temperature Settings and Fuel Supply
The first stop is at your thermostat. Make sure that it is properly set for heating your home and that the temperature setting is appropriate. If the settings seem to be correct, you can try turning your thermostat off and on again to see if this prompts action. It’s also worthwhile to test your thermostat batteries if you have a digital unit. A failure of the batteries could lead to unpredictable system performance.
If you have eliminated this source of concern, you can move on to verifying that your gas supply hasn’t been interrupted. If you have a gas-operated stove, you can check to see if a burner ignites. This should alert you if there has been an outage or disconnect. Contact your utility company for more information in this case.
If gas is still available to your property, you may want to verify that the pilot is lit. You can also check to be sure that the valve to your furnace hasn’t been shut off. You may need to press a reset button for a modern pilot. If you aren’t sure about proper protocol for lighting your pilot, you should consult your owner’s manual or talk to your HVAC company about the procedure. You should also verify that your heater filter isn’t excessively dirty. Additionally, look for open panels, shutting any that may seem to be out of place. At times, sensors can be affected by very simple issues, and you may be able to forego a costly repair visit.
