Most homeowners won’t ever face a red-tagged furnace, but if you do, you need to know what your next move will be—and then proceed quickly, particularly if it happens in the middle of a cold winter.
A red-tagged furnace
When your furnace receives the dreaded red tag, it’s for good reason. This is what has happened when a furnace is red-tagged:
During a routine inspection, an HVAC contractor finds a problem with the heat exchanger. Generally, furnaces are red-tagged when the heat exchanger has cracked, which can lead to serious safety hazards. That’s because your heat exchanger is the component that draws the gases the system produces from the heated air that is then sent into your home. If there’s a crack, or the heat exchanger has been damaged in some way, there’s a significant risk that those gases, including carbon monoxide, will be directed into your home through the ductwork system along with the heated air.
Because of the significant dangers that carbon monoxide pose to your family’s safety, your heating technician will shut the system down, requiring you, by law, to either replace the component or install a new system.
With two options at hand, homeowners need to consider which course of action will provide the most comfort at the most affordable cost:
- Repairing the heat exchanger – Because this component sits at the heart of the furnace, your technician will have to take the furnace apart to access it, driving labor costs up. If your furnace is older, you might be better off replacing the entire system, especially if your warranty doesn’t cover labor.
- Replacing the furnace – This is often the option that gets a higher return on investment, and putting your money toward a new system will increase home comfort and energy savings.
