How Many Parts Does My Heater Have?

Your HVAC system is an intricate unit that warms air and circulates it throughout your home. There are several parts that work together to provide you with the warmth you crave. It’s wise to know what the important parts of this system are in case you ever need repairs or service. Here at Duggan’s One Hour Heating & Air Conditioning, we want you to be informed about the parts of a heater so you can make informed decisions when the time comes.

The Burners, Heat Exchanger, & Flue

Powered by oil, natural gas, or wood, the burners warm the air. You should call for Augusta heating service if your furnace is blowing lukewarm or cold air rather than the warm you were look forward to. The heat exchanger is what conveys heat from one source into another for the burners to warm the air. Heat exchangers go through regular cycles of expansion and contraction, which can lead to cracking. When the heat exchanger of a gas furnace cracks, dangerous carbon monoxide can leak into your home. Regular maintenance will help prevent this and keep your family safe. The flue vents exhaust from the furnace to the exterior of your home. This prevents pollutants and dangerous gasses from entering your home and harming your family. Part of our safety inspections and tune-ups include inspecting the flue to ensure it is free of blockages.

Air Filters & Blower

When the blower stops working, you will feel very little air coming through the vents. There are several things that can go wrong with the blower, including blown fuses, improper positioning, and clogged air filters. Fortunately, we offer heater repair to restore the air flow. Every system runs air through a filter before it goes to the burners. This filter prevents allergens and dust from entering the furnace and clogging it. You should change the filters monthly to keep your system running efficiently.


Most people don’t give their ducts a second thought, but they are important component to how the air is moved throughout your home. Supply ducts take fresh, treated air into the living areas, and special return vents on the opposite sides of rooms pull in the air from the room and send it back to the burners for warming. This completes the circuit and ensures that you have fresh, warm air throughout your home. Invest in regular maintenance and annual tune-ups with Duggan's One Hour Heating & Air Conditioning®. We can ensure that your system is functioning safely and efficiently to protect your family and your home.
