Furnace Troubleshooting and Repair in Metro Vancouver
Furnace Troubleshooting & Repair in Metro Vancouver
From a furnace that won’t turn on to one that blows cold air or cycles on and off, most furnace faults follow recognisable patterns. This guide walks through the common problems, what causes them, and what you can safely check — and when to call ROMA Heating & Cooling for licensed diagnosis and repair across Metro Vancouver. We have kept Lower Mainland homes warm since 1999.
Common Furnace Problems
- No heat — thermostat, igniter, flame sensor, gas supply, or limit faults.
- Blowing cold air — fan set to ON not AUTO, or burners not staying lit.
- Short cycling — dirty filter, overheating, or a dirty flame sensor.
- Won’t turn on — furnace switch off, tripped breaker, open blower panel, or thermostat fault.
- Strange noises — bearings, belts, igniter sequence, or a cracked heat exchanger.
- Error codes — read the control-board flash code to pinpoint the fault.
Furnace Symptom vs Likely Cause
| Symptom | Likely Cause |
|---|---|
| No heat, blower runs cold | Igniter, flame sensor, or thermostat on ON |
| Turns on and off rapidly | Dirty filter or overheating limit trip |
| Completely dead | Switch, breaker, or open blower-door switch |
| Flashing diagnostic light | Read the code for the exact fault |
| Banging or screeching | Mechanical fault — have it inspected promptly |
What You Can Check Safely
- Set the thermostat to Heat, AUTO, and above room temperature; replace dead batteries.
- Replace a dirty filter and open all supply registers.
- Confirm the furnace switch and breaker are on and the blower panel is closed.
- Note any error-code flashes through the sight glass.
- Reset power once; if it won’t heat, call for service.

Frequently Asked Questions
What are the most common furnace problems?
No heat, blowing cold air, short cycling, a furnace that won’t turn on, strange noises, and error codes are the faults we see most often in Greater Vancouver homes.
Why won’t my furnace turn on at all?
Check the furnace switch, the breaker, the thermostat, and that the blower-door panel is fully closed — a safety switch cuts power when it is open. If those are fine, it needs diagnosis.
What does it mean if my furnace blows cold air?
Often the thermostat fan is set to ON instead of AUTO, or the burners aren’t staying lit due to a failed igniter or dirty flame sensor.
How often should a furnace be serviced?
Once a year. Annual maintenance prevents most breakdowns, keeps the furnace efficient and safe, and protects the manufacturer’s warranty.
Do you offer same-day furnace repair?
Yes — we prioritise no-heat calls with same-day and after-hours service across Metro Vancouver.
