Initial contact
When you call, we ask about the symptoms: no heat, strange sounds, error codes on the display. Based on the urgency, we schedule a technician visit, same day whenever cold weather demands it.

Heating Repairs
Furnace failures in Timmins tend to fall into a few common categories, and most of them can be repaired the same day once we know what we are dealing with.
Timmins winters put heavy demand on heating equipment. A furnace running almost continuously at -30C develops stress failures that milder climates rarely see, especially in heat exchangers, igniters, and blower assemblies.
Our technicians test ignition systems, inspect heat exchangers for cracks, check gas pressure and airflow, verify thermostat wiring, and measure temperature rise to pinpoint the root cause instead of guessing at it.
We service all major furnace brands, including LG, Navien, Continental, Napoleon, and budget alternatives, and our trucks carry the common replacement parts. Once the faulty component is identified, most repairs are completed in a single visit.
The Process
Furnace repair starts with a phone call. Tell us what the furnace is doing, or not doing, and we take it from there.
When you call, we ask about the symptoms: no heat, strange sounds, error codes on the display. Based on the urgency, we schedule a technician visit, same day whenever cold weather demands it.
Your technician arrives with diagnostic tools, inspects the furnace, tests the components, and identifies the failed part or system issue.
Before any work starts, the technician explains what needs to be fixed, gives you a clear cost estimate, and answers your questions. No surprises on the bill.
Once you approve the estimate, the technician completes the repair and walks you through exactly what was done.
We verify ignition, airflow, temperature rise, and safety controls to confirm the furnace is heating safely and efficiently before we pack up.
Most repairs are completed within 1 to 2 hours. If a part needs to be ordered, we schedule a follow-up visit as soon as it arrives. Either way, you will know exactly what was wrong, what was fixed, and how to prevent it next time.
Repair or Replace
Not every furnace problem is worth repairing. Age, efficiency, and repair cost all factor into the decision, and the honest answer depends on the furnace in front of us.
Minor repairs like an igniter, flame sensor, or thermostat are almost always worth doing. Major repairs like a heat exchanger, blower motor, or gas valve call for a cost-benefit look based on the furnace's age.
Older furnaces running at 70 to 75 percent AFUE waste 25 to 30 percent of their fuel compared to modern high-efficiency units at 95 percent and better, which can offset the cost of replacement over time.
Our technicians will tell you straight if replacement makes more sense than repair. We are not here to sell you a new furnace if yours can be fixed reliably.
If replacement is the better option, our furnace installation services cover sizing, efficiency options, and installation timelines. Some homeowners also weigh cold-climate heat pump installation as an alternative. We install both and will walk you through the comparison.
Before You Call
Some furnace problems have simple fixes you can check yourself before calling for service. Run through these five checks first. They solve more no-heat calls than you might expect.
Verify it is set to Heat, the temperature is set above the current room temperature, the batteries are fresh if it is battery-powered, and the display is working.
Confirm the breaker has not tripped and the furnace power switch, usually on or near the unit, is in the On position.
A clogged filter restricts airflow and can cause the furnace to overheat and shut down. Replace it if it looks dirty or has not been changed in three months or more.
If you have a gas furnace, verify the gas valve on the supply line is open, with the handle parallel to the pipe.
If your furnace has a standing pilot, check whether it is lit. If not, follow the relight instructions on the furnace label.
Emergency Service
A furnace failure in January in Timmins is not just inconvenient. It is a safety issue, especially for families with young children or elderly residents.
Ironclad Mechanical offers emergency furnace repair when the heat is completely out and indoor temperatures are dropping. We prioritize emergency calls and aim to have a technician on-site as quickly as possible, typically within a few hours depending on call volume and weather conditions.
If you smell gas or suspect carbon monoxide, evacuate immediately and call emergency services first. Then call us.

Northern Ontario Winters
Timmins winters are hard on furnaces. Extended cold snaps mean systems run nearly continuously for weeks, putting stress on components designed for intermittent cycling.
When outdoor temperatures hold below -20C for days, a furnace rarely shuts off. That accelerates wear on blower motors, igniters, and heat exchangers.
Heating a home from -30C outside to +20C inside demands high heat output hour after hour, which stresses burners and heat exchangers.
Northern Ontario winter air is extremely dry. The static electricity that comes with it can affect electronic ignition systems and circuit boards.
High-efficiency furnaces vent through PVC pipes that can ice up in extreme cold, blocking the exhaust and forcing the furnace into a safety lockout.
Regular maintenance before winter, cleaning burners, testing igniters, and checking venting, reduces mid-winter failures. Our technicians live with these winters too, and they know exactly which components are most likely to fail under local conditions.
