4 Crucial Furnace Parts You Need To Repair To Keep Your Unit Functional

Posted on

Many homes have furnaces. These devices heat up air and circulate it throughout the house using a system of ductwork. They're usually located in the basement, closet, or an interior wall. While most people think that the only heating service their furnace needs is an annual tune-up, they could be wrong. Your furnace may need several repairs throughout its lifetime to function optimally. This article discusses four crucial furnace parts you need to repair to keep it functional.


Burners are responsible for igniting the gas that is used to heat air. Over time, the burner assembly may become corroded and damaged. If this happens, your furnace may operate less efficiently or even cause a fire. To prevent this from occurring, professionals should inspect and fix your burners when they malfunction.

Heat Exchanger

The heat exchanger is a crucial part of the furnace, and your appliance may have problems if it's not working correctly. It's responsible for transferring heat from the combustion chamber to the rest of the furnace. If it breaks down, the furnace will not be able to generate enough heat to keep your home warm. If you notice any cracks in the heat exchanger, it's time for a repair. Cracks can cause the furnace to leak dangerous gases, such as carbon monoxide, which may affect your health. When you call in a technician, they'll fix it to keep it running smoothly.

Blower Motor

This component circulates air through the system and is located in the furnace's plenum or main chamber. It contains a fan that pulls air from the return duct and forces it over the heat exchanger. If your furnace isn't blowing warm air, or it's blowing air intermittently, there's a good chance the blower motor is to blame. Call a contractor to inspect and repair the motor if you don't want a complete system breakdown.


If there are leaks or holes in your ductwork, your furnace will work harder and ultimately break down. This component, which is made of sheet metal, delivers the conditioned air from your furnace to every room in your home. To repair the holes or leaks, you will need to contact a professional HVAC contractor.

Furnaces have several parts that need to run optimally. If they malfunction, your furnace won't perform its functions as expected. To prevent this from happening, contact a technician to inspect and repair your furnace regularly. This will keep it in excellent working condition and enable it to heat your home effectively.
