What matters before the visit
No Heat Is Not the Same as a Gas Emergency
A furnace that does not heat, starts and stops, runs the blower without normal heat or shows a control problem can be submitted for repair review. If you smell natural gas or suspect an active gas leak, leave the area and use emergency guidance instead of troubleshooting through the website.
Describe the Heating Sequence You Can Observe Safely
Useful details include whether the thermostat calls for heat, whether the blower starts, whether the system repeatedly attempts to run, and whether an error light or code is visible. Do not open gas components or attempt adjustments to create a better description.
If you smell natural gas, treat it as an emergency.
Gas safety guidance
Leave the area immediately. From a safe location, call 911 or Enbridge Gas at 1-866-763-5427. Do not wait for a website response or operate switches near the suspected leak.

What can change the job
Details That Can Change the Repair or Installation Plan
These are practical details worth sharing because they can affect access, safety, diagnostics or the work required at the property.
Fuel-Burning Work Requires the Right Qualifications
Ontario regulates fuels work. Where the scope involves regulated fuel-burning equipment, the contractor responsible for that work must have the registrations and certified technicians required for the actual service.
Repair Scope Stays Separate From Replacement
If the existing furnace has a repair symptom, choose Furnace Repair. If the main goal is a new furnace or replacement, choose Furnace Installation & Replacement so the request can include venting, connections, equipment location and removal planning.
Show the Installation, Not Just the Label
A wider photo can show stairs, clearances, surrounding equipment, venting, piping or outdoor access that a close-up model label cannot.

Questions homeowners ask
Furnace Repair FAQ
These answers explain what to include and where repair, installation or safety needs a different path.
What if the furnace blows air but the home stays cold?
Describe whether the air is cool or only mildly warm, how long the system runs and whether the thermostat reaches its setting. Those details are more useful than guessing a failed part.
What should I do if I smell gas?
Leave the area immediately. From a safe distance, call 911 or Enbridge Gas at 1-866-763-5427. Do not use the website to troubleshoot an active gas-leak concern.
Can I submit a furnace request without knowing the model?
Yes. Include the model if it is easy to read safely, but the request can still be reviewed based on the property and symptom information you have.
