Myths About Red Tags: Busted by HVAC Pros
Hearing that your furnace or water heater has been red‑tagged can be alarming, and misinformation abounds. Here are some common myths about red tags – and the facts that debunk them.
Myth 1: “Red tags are just a sales tactic.”
While unethical contractors do exist, red tags themselves are not a scam. They are mandated by the Technical Standards and Safety Authority. Licensed gas technicians must attach a warning tag and shut off the gas to equipment that presents an immediate hazard (Type A) or issue a time‑limited warning for serious non‑imminent hazards (Type B). Atel Air notes that some red tags are issued without proper inspection, but the solution is to ask for proof and get a second opinion, not to ignore the tag.
Myth 2: “A red tag means I have to buy a new furnace.”
Not necessarily. A red tag means there is a safety issue that needs to be resolved. For many Type B tags, a qualified technician can repair or replace the faulty component – such as venting, burner adjustments or replacing an aging gas line. Replacement is only necessary when the cost of repairing a major defect (e.g., a cracked heat exchanger) outweighs the value of the unit.
Myth 3: “Only the company that issued the tag can remove it.”
You’re not obligated to use the same contractor. Any TSSA‑licensed gas technician can inspect the equipment, perform repairs and clear the tag. Haven Home Heating emphasises that homeowners can appeal a red tag directly with TSSA if they believe it was issued in error.
Myth 4: “I can ignore a Type B tag; it’s not urgent.”
Type B tags allow you to continue using the appliance temporarily, but the condition must be corrected by the expiry date. Enbridge’s warning tag form explains that if the utility doesn’t receive a clearance from a certified gas technician by the deadline, it must shut off the gas supply. Ignoring a Type B tag can therefore leave your property without heat and potentially expose occupants to growing safety risks.
Myth 5: “Red tags are only for furnaces.”
Red tags apply to any fuel‑burning appliance or piping – furnaces, boilers, water heaters, fireplaces and even gas dryers. Licensed technicians are required by TSSA regulations to tag any equipment that doesn’t meet code and poses a hazard. Venting defects, gas leaks or defective safety controls on any gas appliance can trigger a tag.
Myth 6: “Carbon monoxide isn’t a big concern.”
Carbon monoxide is an odourless, colourless gas that can be deadly.
According to Health Canada’s Health Infobase, unintentional carbon monoxide poisonings continue to be a significant public-health concern in Canada, with thousands of emergency department visits recorded through the Canadian Hospitals Injury Reporting and Prevention Program (CHIRPP).
Red tags and CO alarms are critical tools to prevent tragedies; they shut down or call attention to appliances that could release this invisible killer.
Myth 7: “I’ll know if my equipment is unsafe.”
Some warning signs (like soot, flickering flames or strange smells) can alert you to problems, but many hazards—especially carbon monoxide leaks—are invisible. Gas technicians use instruments to detect issues that homeowners can’t see or smell. That’s why annual inspections and responsive action on warning tags are essential.
Red tags aren’t something to fear – they are a safety mechanism designed to protect you and your tenants. By understanding the difference between Type A and Type B tags, recognizing myths, and working with licensed HVAC professionals, you can ensure your home or rental property remains safe and compliant. Don’t hesitate to seek a second opinion or contact TSSA if you feel a tag has been unfairly issued; above all, prioritize safety over convenience.
