If your furnace in your New Orleans, LA, home is blowing cold air, there are a few things you can do to fix the problem. But first, you need to figure out exactly why your furnace is malfunctioning. Typically, this is a problem caused by incorrect settings on your thermostat, a dirty air filter, or an error with the pilot light. Keep reading to discover the solution to each of these issues.
Thermostat Is Set Incorrectly
If you have ever walked past a vent and felt air blowing that was cool, the problem could be as simple as adjusting the thermostat setting. It’s important to know the difference between having the thermostat set to “on” and “auto.” You want to have it set to “auto” because the “on” setting will cause the furnace’s fan to blow even when the air isn’t getting heated.
Air Filter Is Dirty
When you have a dirty filter, the heater’s airflow gets inhibited. When this happens, your furnace can overheat. This will start the furnace’s safety control, which shuts the burners off. When the filter is dirty, the heater works longer and harder to get your home warm, which makes it more likely to overheat. You want to replace your air filter, so the heat exchanger of the furnace does not get damaged. If this should happen, you should call a professional.
Pilot Light Is Out
Another reason you might be receiving cold air from your furnace is that the pilot light is out. Try to relight it and see if the flame stays on without flickering off. However, if you cannot keep the pilot light burning or it doesn’t want to light, look to see if the gas valve switch of the furnace is on. If gas is not flowing, the pilot light might be dirty.
