Boiler Maintenance and Inspection in Greater Vancouver
We provide professional boiler maintenance and inspection service for a thorough 360-degree tune-up and safety check on your boiler. Our licensed technicians meticulously inspect each component to ensure optimal function and to identify potential hazards or developing repair needs before they lead to expensive breakdowns. Using calibrated diagnostic tools, we pinpoint gas leaks, carbon monoxide risks, and performance issues. After servicing your boiler, you receive a comprehensive written summary of our findings and all work performed.
Carbon Monoxide Testing
We test for carbon monoxide emissions around the boiler and throughout the combustion system using calibrated CO analyzers and combustion testing equipment. This critical safety check ensures no dangerous CO gas is entering your living spaces.
Gas Connection and Leak Inspection
All gas connections, fittings, and components are checked for gas leaks using electronic gas detectors and leak-detection fluid. We verify that all joints are tight and properly sealed per BC Gas Code requirements.
Pressure and Temperature Verification
We measure and ensure pressure and temperature readings are within manufacturer-specified ranges. This includes system water pressure, gas manifold pressure, and supply and return water temperatures.
Error Code and Display Panel Check
The boiler display panel is checked for any active service codes or fault history. Stored error codes are retrieved from the control board memory and diagnosed to identify current or developing issues.
Flue Gas Vent and Combustion Air Inspection
We inspect the flue gas vent piping and combustion air piping for signs of leakage, corrosion, deterioration, or blockages. All vent connections are verified as secure and properly supported.
Joint and Pipe Connection Tightening
All accessible joint and pipe connections are inspected and tightened as needed. This includes water supply lines, return lines, gas connections, and vent joints throughout the accessible boiler system.
Condensate Drain System Inspection
The condensate drain system (drain line, PVC fittings, and drain trap) is inspected for blockages, proper slope, and signs of leakage. The condensate trap is cleaned and flushed to ensure free drainage.
Air Inlet and Vent Termination Check
Air inlet and vent terminations are checked to ensure they are clear and unobstructed. We verify that snow, leaves, debris, or animal nests are not blocking the terminations on the exterior of your home.
Combustion Air Opening Inspection
The combustion air opening is verified as unobstructed with adequate free area for proper combustion. This is especially important for atmospheric-draft boilers that rely on room air for combustion.
Noise and Vibration Assessment
We listen for any unusual noises or vibrations during boiler operation. Banging, kettling, whistling, or vibrating sounds can indicate issues with the pump, heat exchanger, or burner assembly.
Relief Valve and Discharge Pipe Check
The boiler relief valve and discharge pipe are inspected for signs of weeping, leakage, or corrosion. The relief valve is tested to confirm it opens at the rated pressure and properly reseats.
High-Limit, Zone-Valve, and Mixing-Valve Testing
We examine high-limit switch performance to ensure it shuts down the boiler at the correct temperature. Zone valves and mixing valves are cycled and tested for proper operation and response.
Low Water Cutoff Testing
The low water cutoff device is tested to verify it interrupts boiler operation when water level drops below safe limits. This is a critical safety device that prevents dry-firing and heat exchanger damage.
Heat Exchanger Inspection and Cleaning
The heat exchanger is inspected for signs of corrosion, scaling, sooting, or cracking. We clean accessible surfaces and check for proper heat transfer. For condensing boilers, we verify the stainless steel exchanger is clean.
Condensate System Flush and Cleaning
The condensate system is inspected, cleaned, and flushed. For condensing boilers, proper condensate drainage is essential. We check the neutralizer condition where installed and verify the condensate pH is within the acceptable range.
Burner Assembly Service
The burner assembly is inspected and cleaned, including the ignitor and flame sensor. We check for proper flame pattern and colour. Burners are adjusted if necessary for optimal combustion and efficiency.
Wiring and Cable Connection Check
All wiring and cable connections are inspected for stability. Loose or worn wires are identified, tightened, or replaced. We check for signs of overheating, chafing, or rodent damage on wiring.
Water Chemistry and pH Testing
Boiler water pH levels are checked to ensure they are within the manufacturer recommended range (typically 6.5 to 8.5 for closed-loop systems). Improper pH can cause corrosion or scaling and reduce boiler lifespan.
Control Settings and Safety Control Testing
Control settings are reviewed and tested including operating temperature setpoints, differential settings, and outdoor reset curves. Safety controls are tested to confirm proper shutdown under fault conditions.
Post-Service Performance Verification
After cleaning and inspection, the boiler is operated through a complete heating cycle to ensure it is operating at peak performance. We verify smooth ignition, stable flame, proper modulation, and correct water temperature.
Water Regulator Function Check
The water pressure regulator (fill valve) is tested to ensure proper functioning. We verify the auto-fill maintains the correct system pressure and the backflow preventer is operating correctly.
Expansion Tank Examination
The expansion tank is examined for proper air charge and function. A failed expansion tank can cause pressure fluctuations, relief valve discharge, and system damage. We check the tank pressure and integrity.
Ignition and Thermocouple Inspection
The ignition system and thermocouple are examined for proper operation. We check ignition timing, spark quality, and flame signal strength. Worn or degraded components are identified for replacement.
Air Flushing and System Purge
Air is purged from the system to eliminate air locks and ensure proper circulation. We bleed radiators and high points in the system to remove trapped air that reduces heating efficiency and causes noise.
Gas Manifold Pressure Measurement
Gas manifold pressure is measured at the gas valve outlet and compared to manufacturer specifications. Incorrect gas pressure affects combustion quality, efficiency, and can lead to sooting or burner damage.
Safety Limit Switch Inspection
All safety limit switches are inspected and tested including high temperature limit, flame rollout switch, blocked vent switch, and low water cutoff. Each safety device is verified to shut down the boiler when required.
Safety Reminder
If you smell gas, suspect carbon monoxide or believe there is an immediate danger, leave the property and contact emergency services or the appropriate gas emergency authority. Do not remain inside — exit the building immediately and call for help from outside.
