NTI Boiler Repair in Vancouver
Red Seal–certified NTI boiler repair for Vancouver homes and buildings. We diagnose lockout and hold codes shown on the boiler control display and get your heat and hot water back — same-day, often within 2 hours.
NTI boilers — Canadian-built condensing boilers engineered for cold climates — stainless fire-tube heat exchangers, deep modulation, and strong warranties make NTI a Lower Mainland favourite. If yours is showing a fault in Vancouver, our Red Seal Gas Fitter–certified technicians service TFTN Trinity Fire Tube heating-only boilers (85,000–399,000 BTU/hr), FTVN fire-tube condensing boilers, and TRX condensing combis (95–96% AFUE) across the Vancouver area.
Vancouver's older West Side and East Side homes often have legacy cast-iron boilers and original mid-century hydronic systems. We service both heritage installations and modern condensing combi retrofits across all neighbourhoods.

Common NTI Faults We Repair in Vancouver
NTI reports problems through lockout and hold codes shown on the boiler control display. These are the faults our technicians diagnose most often on Vancouver service calls:
- Ignition Lockout
The burner fails to light after repeated attempts and the control locks out. Common root causes: a worn igniter or flame-sensing electrode, low gas inlet pressure under load, or a gas valve drifting out of spec. The most frequent NTI no-heat call we attend in Metro Vancouver.
- Low Water Pressure Lockout
NTI controls hold or lock out when system pressure drops below the safe threshold. A slow leak at a fitting, radiator valve, or expansion tank is usually behind gradual pressure loss — repressurizing without finding the leak only masks the fault.
- Blocked Condensate / Drain Faults
Condensing operation produces acidic condensate that must drain freely. Blocked traps and frozen exterior drain lines are common during Lower Mainland cold snaps and shut the boiler down as a safety measure.
- Flame Signal / Sensing Faults
A degraded flame-sensing electrode or poor burner grounding causes the control to lose flame proof mid-cycle, producing short-cycling and intermittent heat. Cleaning or replacing the electrode and verifying combustion restores stable operation.
- Circulator / Flow Faults
Restricted system flow — a seized circulator, air-locked loop, or closed zone valve — causes rapid temperature rise and overtemp protection trips. Requires flow diagnosis rather than repeated resets.
NTI Repair Cost in Vancouver
A diagnostic service fee applies to all NTI repair calls and is credited toward the repair if you proceed. Typical NTI repair ranges in BC:
| Repair | Typical range (CAD) |
|---|---|
| Igniter / flame-electrode replacement | $175–$300 |
| Gas-valve replacement | $380–$580 |
| Condensate trap or drain repair | $150–$320 |
| Circulator pump replacement | $450–$850 |
| Heat-exchanger chemical descaling | $220–$320 |
We verify gas inlet pressure under full load and confirm post-repair combustion values with a digital analyzer — essential on deep-modulating fire-tube boilers like the TFTN and TRX.
