Red Tag Furnace
Free Red-Tag Furnace Second Opinions Across Ottawa
A Clear Second Opinion Before You Decide What Comes Next
Having a furnace red tagged during an Ottawa winter is stressful. The notice identifies a safety condition that must be taken seriously, but it does not automatically mean every furnace must be replaced.
AirZone HVAC Services currently offers a free second opinion for red-tagged furnaces across greater Ottawa. Our in-house team reviews the written notice, examines the reported condition, and explains whether a compliant repair, replacement, or another next step makes sense.
What Does a Furnace Red Tag Mean in Ontario?
A furnace red tag, also called a safety violation or warning notice, means a certificate holder or gas distributor found an unacceptable condition involving a gas appliance or its installation. Ontario’s rules address deterioration, piping, venting, combustion air, clearances, and other conditions that may impair safe operation. The governing requirements appear in sections 13 and 14 of Ontario Regulation 212/01.
Immediate Hazard
When the condition presents an immediate hazard, the gas supply to the appliance must be shut off and the written notice directs that it not be used until the condition is corrected.
The owner must not operate the furnace, remove the notice, or permit anyone to bypass the shutdown. A certificate holder must verify the correction before the notice can be removed.
No Immediate Hazard
A non-immediate safety violation identifies a condition that still requires correction by the expiry date written on the notice. Do not guess how much time remains.
Ontario law permits a specified period no greater than 90 days. Enbridge Gas currently states that its Category B notices allow up to 42 days.
Important: “Type A” and “Type B” are common industry terms. The safest guide for your home is the written notice itself, including whether the appliance was shut off and the exact correction deadline.
Common Furnace Conditions That Require Attention
A safety notice should identify the specific condition found. The right solution depends on the furnace, installation, test results, and wording on the notice—not on a generic list online.
Venting or combustion air
Damaged, obstructed, deteriorated, or incorrectly arranged venting and combustion-air conditions.
Gas piping or controls
Conditions involving gas piping, fittings, valves, controls, or other fuel-handling components.
Equipment deterioration
Heat exchanger concerns or other deterioration that may impair the furnace’s safe operation.
Installation or clearances
Unsafe clearances, altered equipment, or an installation that does not meet applicable requirements.
What to Do After Your Furnace Is Red Tagged
Smell gas or have a carbon-monoxide emergency?
Leave the building and call from a safe distance. For a suspected natural-gas leak in Ontario, call Enbridge Gas at 1-866-763-5427 or 911 and follow its gas-leak safety guidance. If a CO alarm sounds and anyone has symptoms, move outside and call 911.
How AirZone’s Free Red-Tag Second Opinion Works
A second opinion does not override a valid safety notice. It gives you another qualified assessment of the condition and the available path forward.
- We review the notice and ask what happened during the original visit.
- The technician examines and tests the reported condition as appropriate.
- You receive a clear explanation of what can be confirmed and what remains uncertain.
- Repair or replacement options are discussed only after the findings are understood.
Can a Red-Tagged Furnace Be Repaired?
Sometimes. A red tag identifies a condition that must be corrected; it is not automatically a replacement order. The decision depends on what failed, whether a compliant repair is available, the furnace’s condition, parts availability, repair value, and the notice deadline.
When repair may make sense
A targeted repair may be appropriate when the unsafe condition can be corrected, suitable parts are available, and the furnace remains a reasonable system to keep. AirZone’s furnace repair team can explain the diagnosis and quote approved work.
Review furnace repair optionsWhen replacement may make sense
Replacement may deserve consideration when the required repair is unavailable, unreliable, or poor value compared with an older furnace’s remaining life. Compare current furnace options and AirZone’s furnace installation process.
Plan a furnace replacementWhat happens after the condition is corrected?
Ontario rules restrict who may remove the notice and require the certificate holder to endorse and deliver it to the gas distributor. Enbridge says a TSSA-registered contractor completes the repair and sends the required information. AirZone will explain the documentation and notification steps that apply to your notice.
Call for Emergency Furnace Help When Waiting Is Not Safe
If an immediate-hazard notice leaves your home without heat during freezing weather, tell AirZone that the furnace was shut off and read the notice details to the dispatcher. AirZone provides 24/7 emergency HVAC service for urgent no-heat situations across Ottawa.
Emergency availability does not change the safety notice: tagged equipment must remain off until the reported condition has been corrected and the required process is complete.
Can Annual Maintenance Help Avoid a Future Red Tag?
Annual furnace maintenance cannot guarantee that a safety notice will never be issued. It can, however, give a technician an opportunity to identify visible deterioration, venting concerns, combustion issues, filter restrictions, and operating changes before winter demand increases.

Common Questions About Furnace Red Tags in Ontario
What does a red tag on a furnace mean in Ontario?
It means a certificate holder or gas distributor identified an unacceptable condition involving a gas appliance or its installation. The notice should describe the condition, state whether it is an immediate hazard, and provide any applicable correction deadline.
What is the difference between Type A and Type B furnace red tags?
A Type A or Category A notice identifies an immediate hazard and requires the gas supply to be shut off. A Type B or Category B notice identifies no immediate hazard but still requires correction by the expiry date on the notice.
Can I turn my furnace back on after it has been red tagged?
Do not restart a furnace that was shut off for an immediate hazard. Do not remove the notice or restore the gas yourself. The condition must be corrected and the notice handled by a certificate holder as required by Ontario law.
Does a red-tagged furnace always need replacement?
No. Some conditions can be repaired, while others make replacement safer or better value. The answer depends on the reported defect, test findings, furnace condition, parts availability, and whether a compliant repair is possible.
Does AirZone offer a free second opinion?
Yes. AirZone currently offers a free second opinion for red-tagged furnaces across greater Ottawa. Keep the notice and any supporting report available so the technician can review the exact condition identified.
How long do I have to correct a non-immediate furnace violation?
Follow the expiry date written on your notice. Ontario Regulation 212/01 permits a correction period no greater than 90 days, while Enbridge Gas currently says its Category B notices allow up to 42 days. Do not assume the longest period applies to your notice.
Who can remove a furnace safety notice?
Ontario’s regulation says the notice may only be removed by a person holding the certificate required for that purpose. The certificate holder must endorse the notice and send or deliver it to the distributor.
What should I do if the shutdown leaves my home without heat?
Call AirZone at 613-592-5770 and explain that the furnace was shut off under a safety notice. During freezing weather or when the home may become unsafe, ask for 24/7 emergency HVAC service. Do not operate the tagged furnace while waiting.
