A Look at Common Furnace Repairs

May 14, 2024

The average combustion furnace is expected to last a maximum of 20 years. However, there are many factors that affect the longevity of your home’s heating system, including its quality and the quality of its installation, your average usage habits, the system’s maintenance and repair history, and the type of thermostat you have installed. In most cases, heating issues can be handled easily with simple Detroit furnace repair from your trusted HVAC provider. Especially if your furnace is less than ten years old, it’s likely that any heating issue you may encounter can be solved with furnace repairs, rather than requiring you to consider heating system replacement.

Air Handler Repairs

Forced air systems require an air handler to push heated air up into and through the ducts of your home. This air handler operates much like a fan, and provides air movement for both your furnace and your air conditioner. Because the air handler is in constant use, it is at higher risk for wear; when the air handler wears out or becomes damaged, you won’t feel any air coming from your air registers, even while your furnace is running. If your air handler is still working but isn’t running efficiently, you may notice a burning smell or hear screeching or grinding sounds while your furnace is active. Your HVAC service can quickly assess and repair air handler problems by replacing worn parts and lubricating moving components for efficient heating once more.

Heat Exchanger Repairs and Replacement

Furnaces use a heat exchanger to transfer heat from combustion into the air that is circulated through your home. This simple system makes your furnace more efficient, but cracks or other damage can rob your furnace of efficiency and increase energy consumption, as well as allow combustion fumes to accumulate. Cracked heat exchangers typically produce an unpleasant odor, which you may notice when your furnace is running. You may also notice that surfaces in your home seem dirtier, as your furnace will burn less efficiently and release excess soot into the air. Once your HVAC service has identified your furnace problem as the heat exchanger, they will decide whether the damage can be repaired or whether your furnace might benefit from an all-new heat exchanger. Even if a new heat exchanger is required, it can be installed quickly to restore your home comfort.

Pilot Assembly Cleaning and Repairs

Combustion furnaces often use a pilot light to provide the flame that lights the burners while the furnace is active. If the pilot assembly experiences problems, it will need to be repaired to restore the furnace’s ability to create a flame and heat your home. Pilot problems are often first detected as a lack of heat from the furnace. If you can access the pilot, you may also be able to see that the light has gone out. In many cases, pilot problems are associated with buildup on the assembly or issues with the thermocouple, which regulates the flow of gas. Your furnace repair service can remove and clean or repair the system to restore a consistent pilot light.
