It seems at the wrong times, your home heater starts to blow cold air. There are many reasons why your furnace is blowing cold air instead of nice warm air to heat your home. Majestic AC will go over the more common issues that can cause your heater to not work properly and some fixes.
Top 5 reasons why your home heater maybe blowing cold air.
1. The pilot light is not working.
Many times when your heater is not warming your home, the culprit is a faulty pilot light that starts up your burners. If cold air is coming from your vents when the heater is on, check the pilot light on your gas furnace system. If the pilot light is not on, follow the instructions for your furnace to reset or light the pilot.
There maybe more complex issues regarding your pilot light not igniting your furnace like a dirty ignition sensor or malfunctioning part. This usually requires turning gas off to your furnace. Many people find it uncomfortable at this level of work. Feel free to call Majestic AC to service your furnace.
2. Dirty air filter restricting air flow.
Just like in the summer, you must replace your air filters regularly in the winter. A common sign that your air filter maybe restricting air flow include longer than normal heating cycles and overheating which causes your furnace to blow cold air. Based on your lifestyle like pets, smoking, and other issues change your air filter every 90 days or less. Those with pets should take a look every 30 days. Keeping your air filters are one of the easiest things you can do to make sure your furnace is running at its most efficient.
3. Gas supply to your furnace is not optimal.
If you have an issue with the gas supply to your furnace, many systems will deactivate to protect you and your home. The furnace may cut off the gas supply and blow normal, cold air. This is a problem that should be addressed by professional HVAC technicians. Call Majestic AC to look at your furnace and repair issues regarding your gas line and furnace.
4. There is an issue with your thermostat.
First, let’s check to see if your thermostat is set to heat. Many times, if the thermostat is on AC or cool, it will run and blow normal, cold air as it cycles. Ensure that your thermostat is set to heat and the temperature is set higher than the air temperature in your home. If all this is right, see if your smart thermostat has any error codes. Some of these may be easily cleared. Your thermostat might be actually malfunctioning. In this case, contact Majestic AC to troubleshoot your thermostat.
