Published: July 22, 2026 — CANRO Heating & Cooling — Greater Vancouver, BC
Boiler Diagnostic Tools
Our technicians use: manufacturer-specific diagnostic software (Navien, Viessmann, Baxi), combustion analyzers for flue gas testing, multimeters for electrical testing, manometers for gas pressure measurement, and thermal imaging for temperature differentials. These tools allow us to identify the root cause quickly and accurately.
Common Boiler Faults We Diagnose Fast
Lockout/error codes: read the code, check the manual, test the associated component. No heat: check pressure, check pump operation, check zone valves, check thermostat signal. Leaks: visual inspection, pressure test, component isolation. Pressure loss: check for visible leaks, test expansion tank, check PRV. Kettling: listen for location, check water chemistry, inspect heat exchanger.
Diagnostic Cost and Value
Our diagnostic fee covers the time to identify the problem. Most boiler diagnoses are completed within 30-60 minutes. The diagnostic fee is waived if you proceed with the recommended repair. A thorough diagnosis ensures we fix the right problem — not just the symptoms.
