NTI Boiler Repair in Metro Vancouver

Red Seal–certified technicians servicing NTI TFTN, FTVN and TRX condensing boilers. Same-day diagnosis and repair across Greater Vancouver.

NTI Boiler Repair Done Right

When your NTI boiler locks out, you want a technician who works on these Canadian-built fire-tube boilers every week. Our team diagnoses NTI lockout and hold codes directly from the control display, verifies gas pressure under load, and confirms every repair with a digital combustion analyzer — essential on deep-modulating boilers like the TFTN and TRX.

We carry common NTI components — igniters, flame electrodes, sensors — on the truck, so most no-heat calls are resolved in a single visit. If a repair no longer makes financial sense against replacement, we tell you straight and quote both options.

NTI Faults We Repair Most

Ignition lockout: burner fails to light — igniter, flame electrode, gas pressure, or gas valve.
Low water pressure: control holds below safe pressure — find the leak, not just the top-up.
Blocked condensate: frozen or clogged drain shutting the boiler down in cold snaps.
Flame-sensing faults: short-cycling from a degraded electrode or poor grounding.
Circulator & flow faults: overtemp trips from seized pumps, air locks, or closed zones.
