If you’ve discovered a red tag on your HVAC unit, don’t panic—but don’t ignore it either. A red tag is a serious warning issued by a licensed technician indicating that your system is unsafe to operate. Whether it’s due to a gas leak, cracked heat exchanger, carbon monoxide risk, or another safety concern, the red tag is there to protect your home and your family.
So, what should you do next? Let’s break it down.
What Does a Red Tag Mean?
A red tag typically falls into one of two categories:
Type A – This means your HVAC unit poses an immediate danger (such as a gas leak or carbon monoxide hazard) and must be shut off right away.
Type B – This means your system isn’t up to code or may become dangerous if not addressed soon. You’ll usually have a grace period to fix the issue.
In both cases, it’s critical to act quickly. Red tagging is regulated and documented, and ignoring one can affect your homeowner’s insurance or property sale in the future.
Common Reasons for Red Tags
Some of the most common issues that lead to a red tag include:
- Cracked or damaged heat exchangers
- Carbon monoxide leaks
- Poor ventilation or blocked flues
- Electrical hazards
- Gas line issues
- Improper installation or code violations
If your unit was recently inspected and red-tagged, the technician should have provided a report explaining the exact issue.
Can I Remove the Tag or Keep Using the System?
No—and please don’t try. A red tag is a legal warning issued for your safety. Tampering with it or continuing to use the equipment without making necessary repairs can not only risk your family’s safety but may also come with legal or insurance consequences.
