Boiler Maintenance & Inspection

Our Complete 30-Point Boiler Inspection & Tune-Up Routine

Every boiler maintenance visit follows our comprehensive 30-point checklist. This isn't a quick look-over — it's a full systems inspection designed to catch problems before they become emergencies. Here's exactly what we do:

• Test for carbon monoxide emissions using calibrated CO analyzer
• Check all gas connections and components for gas leaks with electronic leak detector
• Measure and ensure pressure and temperature readings are within manufacturer specifications
• Look for any service codes or errors on the display panel and diagnose root causes
• Check flue gas vent piping and combustion air piping for leakage, corrosion, or deterioration
• Ensure all joint and pipe connections are tight and properly sealed
• Inspect the condensate drain system (drain line, PVC fittings and drain trap) for blockages
• Ensure air inlet and vent terminations are clear and unobstructed
• Check to ensure the combustion air opening is unobstructed
• Check for any unusual noises or vibrations during operation
• Inspect the boiler relief valve and discharge pipe for signs of weeping or leakage
• Examine high-limit switch, zone-valve, and mixing-valve performance
• Have low water cutoff tested for proper operation
• Inspect and clean heat exchanger — remove soot, scale, and debris
• Inspect, clean and flush condensate system to prevent blockage
• Inspect and clean burner assembly including ignitor and flame sensor
• Adjust burners if necessary for optimal combustion efficiency
• Ensure all wiring and cables have stable connections; replace loose and worn wires
• Check water pH levels to prevent corrosion and scale buildup
• Check control settings and test all safety-controls
• Ensure boiler is operating at peak performance after cleaning and inspection
• Ensure proper functioning of water regulator and fill valve
• Examine expansion tank — check air charge and diaphragm condition
• Examine ignition system and thermocouple for wear and proper operation
• Perform air-flashing on the system to remove trapped air
• Measure gas manifold pressure and adjust if needed
• Inspect safety limit switches and verify trip points
• Test thermostat communication and zone controls
• Verify boiler cycling and modulation across all firing rates
• Replace or clean air filter if applicable

Safety Testing: Carbon Monoxide & Gas Leak Detection

Carbon monoxide (CO) is the number one safety concern with any gas appliance. Our technicians use calibrated electronic CO analyzers to measure emissions at multiple points — the flue, near the heat exchanger, and in the living space. We test at both low-fire and high-fire conditions to ensure safe combustion across the full operating range.

Gas leak detection is equally thorough. We use electronic combustible gas detectors (not just soap bubbles) to scan every gas connection, fitting, and valve. Even the smallest leak is documented and repaired immediately. Under BC's Safety Standards Act, any gas leak must be addressed by a licensed gas fitter — which all our technicians are.

• CO testing at flue and ambient air using calibrated analyzer
• Electronic gas leak detection on all connections and components
• Combustion analysis: CO, CO₂, O₂, excess air, and flue temperature
• Gas valve operation and safety shutoff verification
• Documented CO levels provided in your service report

What You Get After Every Service

After every boiler maintenance visit, you receive a detailed written service report covering all inspections performed, measurements taken, and any recommendations for repairs or future maintenance. This is professionally documented — useful for warranty claims, home insurance, and resale disclosures.

If we find any issues during the inspection, we explain what they mean, show you the evidence, and provide a fixed written quote for any recommended repairs. There's never any pressure — just honest advice from licensed professionals.

• Detailed written service report with all measurements documented
• CO and combustion analysis readings
• Digital photos of any issues found
• Written repair recommendations with fixed quotes if needed
• Next service date reminder for warranty compliance
• Rebate eligibility documentation where applicable

Why Annual Maintenance Matters

An unmaintained boiler loses 2-5% efficiency per year due to soot buildup, scale deposits, and component wear. Over 5 years, that's a 10-25% increase in your gas bill for the same heat output. Annual maintenance pays for itself through lower energy costs alone.

Beyond efficiency, most manufacturer warranties require proof of annual professional servicing. Without it, a $2,000+ heat exchanger failure might not be covered. We've seen this happen — homeowners skip maintenance to save $200, then face a $3,000 repair that would have been covered under warranty.

Finally, safety: a blocked flue or cracked heat exchanger can release carbon monoxide into your home. Annual inspection catches these issues before they become dangerous.
