Understanding Your Gas Furnace

Understanding your gas furnace will help you maintain it for a longer lifespan. A popular type of furnace is a central air system, which heats air in one place in your home and then distributes it throughout your home via ducts and vents. Your furnace contains many parts that work together to provide you with the most comfort. Various components of your gas furnace are the controlling mechanism via thermostat, gas valve, burners, heat exchanger, blower, and the ventilation system. When your furnace creates heat, resulting combustion gases are vented out of your home through a pipe.

How Your Gas Furnace Works

When you raise the temperature, your thermostat sends a signal to your gas furnace. Additionally, when the thermostat detects the air temperature is dropping below your set number, it activates the furnace. When the furnace receives a signal, the furnace gas valve opens and ignites the burner component. The gas valve also works with your thermostat to regulate the amount of gas that flows into your furnace. The gas ignites in the furnace and hot air is spread through the duct system in your home. After the thermostat reaches the set number, your furnace shuts down. You can consider investing in a smart thermostat as it can save money on utility bills.

Regular Maintenance

It is critical that you schedule yearly furnace preventative maintenance with your technician before the heating season starts. It will ensure that you will catch all issues before they become major. You don’t want to end up with your furnace not working properly on a cold night. Your technician will be able to test your heat exchanger for cracks. They can also clean your pilot light and inspect the ventilation system. Additionally, as part of regular maintenance, it is a good idea to replace the furnace filter every three months. You should also test your smoke and carbon monoxide detectors every month to make sure they are working correctly.
