How Trane Furnaces Work: Calgary Homeowner Overview
A Trane furnace has several critical components: the ignitor, burner, flame sensor, blower, control board, and heat exchanger. Calgary winters put these parts under heavy use, which can accelerate wear. Knowing the function of each part helps homeowners recognize when a problem is minor versus one that requires professional attention.
Common Trane Furnace Problems in Calgary
Here are the common issues you might encounter with your trane furnace:
1. Furnace Won’t Ignite
Issues with ignition can stem from the thermostat, power supply, or a worn ignitor. Sometimes the gas valve is closed, preventing heat production. If your furnace fails to ignite after checking these basic items, professional diagnostics may be required. For a full Trane troubleshooting guide, see Trane’s guide to common heating problems.
2. Furnace Blowing Cold or Lukewarm Air
Blocked filters, restricted airflow, or a tripped limit switch are common reasons for weak heating. Calgary homeowners should inspect filters regularly; replacing them can improve airflow and heat output. If the furnace still blows cold air, a trained technician can check the burner and safety controls. Learn more about maintaining your furnace with our furnace tune-up and maintenance services.
3. Blower and Fan Problems
The blower may run continuously, fail to start, or produce unusual noises. These issues often stem from a failing motor, worn bearings, or a malfunctioning control board. Regular inspections during seasonal maintenance can prevent major breakdowns. Consider furnace duct cleaning to ensure airflow is unobstructed.
4. Flame Sensor and Ignitor Issues
Flame sensors can become dirty, preventing proper ignition, while ignitors may wear out over time. Attempting repairs without experience can damage delicate parts. Certified technicians have the tools to clean, test, and replace components safely.
5. Overheating and Short Cycling
Overheating often triggers the high-limit switch to prevent damage. This can be caused by restricted airflow, dirty burners, or a compromised heat exchanger. Repeated short cycling reduces efficiency and may damage other components, making professional evaluation necessary.
6. Heat Exchanger Concerns
A cracked or damaged heat exchanger is a serious safety issue, posing carbon monoxide risks. If your furnace is older or repeatedly overheating, it may require replacement. For Calgary homeowners, a trained technician ensures this is handled safely and meets code requirements.
DIY Checks for Calgary Homeowners
For minor troubleshooting before calling a professional, follow these steps:
- Verify thermostat settings and power.
- Replace or clean the air filter. Learn how in this guide.
- Ensure the gas supply is on.
- Observe for error codes or unusual flame behavior.
Do not attempt to repair ignitors or flame sensors unless you have experience, as incorrect handling can void warranties or create safety hazards.
Preventive Maintenance Tips for Trane Furnaces in Calgary
Regular maintenance keeps your furnace efficient and reduces emergency repair costs. Recommended tasks include:
- Annual inspections of burners, flame sensors, and safety switches.
- Cleaning or replacing filters every 1–3 months.
- Checking blower operation and ductwork for blockages.
- Using monitoring tools or smart thermostats for early problem detection.

- Minor repairs, like replacing a sensor, typically range from $150–$500.
- Major repairs, such as blower motors or heat exchangers, may exceed $1,000.
If your furnace is older or frequently needs repairs, consider whether replacement may be more cost-effective. Learn more in our repair or replace guide and new furnace cost guide.
