Boiler diagnostics for faults that won't be guessed away
Instrumented boiler diagnostics in Greater Vancouver: combustion analysis, gas-pressure checks, electrical and control testing that pin down the actual cause of a fault, including intermittent faults and problems earlier visits did not resolve.

Boiler Diagnostics for Vancouver homes and buildings
Some boiler faults announce themselves with an error code; many do not. Codes narrow the search, but the cause can be a sensor drifting out of specification, a gas-pressure problem under load, a condensate line that only fails in cold weather, or an intermittent electrical fault. Diagnostics replaces guesswork with instruments: the boiler is tested under operating conditions and its actual behaviour is recorded.
Diagnostics also serves systems that have already been visited without resolution, recurring faults after parts were changed, and second-opinion situations where you want findings documented before more money is spent. The visit ends with a written statement of the fault, the evidence and the repair options, and no repair proceeds without your approval.
Gas permits. The City of Vancouver issues gas permits: all new natural gas installations and alterations require a permit, applied for online through the city's permitting account. The city permits fully detached homes on a single gas meter at 2 psig (14 kPa) or less, and other buildings with a meter pressure of 2 psig or less and a total connected load no greater than 409,600 BTU/hr (120 kW); other installations apply to Technical Safety BC.

Mechanical permits. As of July 1, 2022, a City of Vancouver mechanical permit is required to install or replace heating and cooling systems, including boilers, furnaces and heat pumps, in new and existing buildings. A mechanical permit is not needed for maintenance or repairs of existing systems, or for replacing an appliance with one of the same fuel, type and capacity; replacing a gas boiler of the same type and capacity still requires a gas permit.

Process
How it works
- 01
Describe the fault
Code, behaviour, frequency and weather conditions are noted before the visit.
- 02
Instrumented testing
The technician measures combustion, pressures and electrical behaviour rather than guessing.
- 03
Diagnosis in writing
The cause, the evidence behind it and the repair options are documented.
- 04
Approve or not
Any repair is quoted and agreed separately; nothing is done without your approval.

Frequently asked questions
My boiler's error code points to a sensor. Why not just replace it?
Codes identify suspects, not verdicts. A sensor fault is often the symptom of a real cause such as a gas-pressure or flow problem, which is why the diagnostic visit tests the system rather than ordering parts from the code alone.
Do you investigate intermittent faults that only happen sometimes?
Yes. Control history, logged data and repeated firing-cycle testing are used where the boiler records them, and the limits of what can be confirmed are stated honestly.
Is this the same as a repair call?
No. Repair fixes a confirmed fault; diagnostics establishes what the fault actually is. When testing already makes the cause obvious, the technician can move straight to a quoted repair, with the diagnosis as the evidence behind it.
