It’s freezing inside your house, and you turn to your furnace for some much-needed warmth. But instead of hot air, the furnace starts blowing cold air. If this happens to you, don’t panic. There are a few things you can try before contacting a professional furnace service in Paradise, CA. First, inspect some of the components that might be causing the problem,
Reasons Why Your Furnace Blows Cold Air
Here are some most prevalent reasons that explain why your furnace is beginning to blow cold air:
• Bad Thermostat
When the temperature inside your house reaches the desired temperature on the thermostat, it signals your HVAC system to stop the cycle. It begins the cycle again if the room temperature drops. Sometimes, loose wires or old thermostat sensors may cause the thermostat to function improperly.
How to Fix:
1. Check the temperature on your thermostat.
2. Check that it is not turned on.
3. If it is, return the switch to the auto position. Your furnace should blow warm air after restoring the proper setting.
4. Replace the batteries if the screen is invisible.
• Dirty Air Filter
An air filter is a necessary component of any HVAC system. When these filters are clean, they give clean, fresh air to your home. However, a dirty air filter might cause airflow problems, and the furnace might not get enough air to continue the combustion process.
How to Fix:
1. If you’re unsure about the state of your air filter, inspect it visually.
2. Replace it if it appears to be excessively dirty and clogged. Ensure to clean it weekly to avoid airflow problems.
3. Contact us so we can provide a furnace service expert in Yuba City, CA, to assist with your issue and determine which air filter is compatible with your furnace system to fit your home.
• Ignitor Malfunction
An older furnace may have a pilot light to start the combustion process. However, modern furnace models use an electric igniter to ignite gas for combustion. If the pilot light fails or the ignitor fails, the gas will not ignite, resulting in improper airflow from the furnace.
How to Fix:
To properly relight the pilot, follow your furnace’s owner’s manual instructions. You can also contact us for furnace repair in Yuba City, CA, to replace the damaged component and relight the ignition system.
• Dirty Flame Sensor
Once started, pilotless ignition furnaces employ a flame sensor to ensure the gases are burning. If the flame sensor is clogged, your furnace will switch on and begin heating but will quickly cool.
How to Fix:
If you’re acquainted with furnace components, you may clean the flame sensor manually, which should restore the heating function of your furnace. Contact us for furnace repair service in Yuba City, CA, if you require further assistance.
• Gas Supply
If your gas supply goes out or is just inadequate, the furnace will not be able to produce heat but will continue to run the blower, producing frigid air.
How to Fix:
If it’s a whole-house problem, check with your gas company, or call us for furnace service in Paradise, CA, if the furnace isn’t getting enough gas.
