There are several components on your furnace that must remain in good condition to ensure the unit runs safely. For example, if the heat exchanger were to develop a crack because of neglected maintenance, this would raise the risk of carbon monoxide leaks. Most experts recommend annual tune-ups to keep heaters operating safely and at peak performance during cooler weather. Keep reading to learn which tasks matter most for your home’s comfort and your family’s well-being.
Checking the Heat Exchanger for Corrosion and Cracks
The heat exchanger on the furnace plays a large role in how safely the equipment runs because it keeps the combustion gases separate from the air circulating throughout the house. But over time, it can develop corrosion from years of heating cycles, moisture, and normal wear. Some of the corrosion may become so severe that the heat exchanger cracks and leaks carbon monoxide, which is a major hazard to your health. During maintenance, the technician inspects this component to ensure it works correctly. If the part has significant signs of corrosion or cracks in it, it’ll most likely need replacement.
Making Sure the Burners Maintain Proper Combustion
If the burner flames are yellow instead of blue, this is a safety issue that needs immediate attention. A technician will clean them during maintenance to ensure the flames burn blue and without flickering. The cleaning process usually entails taking a soft-bristle brush and gently removing dirt and debris from the burner ports.
Cleaning the Flame Sensor and Testing the Ignition System
Regular maintenance is also important because it gives the technician a chance to look at the flame sensor. If it’s covered in dirt or oxidation, this can interfere with its ability to detect the burner flame, which can end up causing the furnace to shut off unexpectedly. If you keep noticing the furnace starting and shutting off shortly afterward, it may have a dirty flame sensor. A technician will clean the sensor during maintenance, followed by testing the ignition system to verify everything runs safely.
Inspecting the Gas Valve for Leaks and Damage
One of the most common safety problems that people have with furnaces is gas leaks, and these can occur in the gas lines or around the gas valve. A loose fitting may allow gas to slowly leak from the connection, putting the whole home at risk of a fire or explosion. While performing maintenance, the technician will inspect the gas line and gas valve for leaks, corrosion, and any other damage that could compromise safe operation.
Your home and family deserve to be safe at all times, and this is exactly why you should take time each year to book professional furnace maintenance. A system that runs safely does much more than protect your loved ones; it also helps the equipment run more efficiently, which leads to a more comfortable home and lower heating costs.
