What Our Boiler Maintenance Services Include
Our comprehensive boiler maintenance service covers 3 core categories: full system inspection, cleaning and combustion analysis, and controls calibration. The boiler maintenance checklist covers 12 critical components, delivering a complete maintenance service from first diagnostic to final report.
Full Boiler System Inspection and Diagnostic Testing
Our technicians inspect the heat exchanger, thermocouple, expansion tank, circulator pump, pressure relief valve, and zone valve at every boiler inspection in Lexington.
Inspection checklist:
- Inspect the thermocouple for carbon deposits, corrosion, and electrical resistance
- Test the heat exchanger for cracks and thermocouple flame signal accuracy
- Check the expansion tank pressure, circulator pump flow, and pressure relief valve
- Verify the thermocouple pilot light and flame sensor against flame detection thresholds
- Test limit switches, safety switches, and electrical connections for trip accuracy
- Inspect pipes, radiators, flue, zone valve, thermostat, and boiler controls
Our technicians use diagnostic equipment to identify thermocouple wear, heat exchanger damage, and expansion tank failure before recommending repairs.
Cleaning, Combustion Analysis, and Safety Device Verification
Our technicians clean internal components, test combustion efficiency, and verify all safety devices at every boiler maintenance visit. Cleaning removes sediment from pipes, scale buildup and carbon buildup from the heat exchanger, while combustion analysis verifies the air-fuel mixture, gas pressure, and thermocouple flame output.
Boiler safety check covers:
- Test the thermocouple flame sensor, safety switches, and limit switches for cut-off accuracy
- Inspect heat exchanger surfaces, pipes, expansion tank fittings, and pump inlet for corrosion
- Verify thermocouple output, CO detector levels, and carbon monoxide gas leak detection
- Confirm pump performance, expansion tank pressure, and all pipe connections for safe operation
All boiler service meets Massachusetts code standards for safe operation.
Thermostat Calibration, Boiler Pressure Testing, and Controls Verification
The technician calibrates the thermostat, tests boiler pressure, and verifies boiler controls during every maintenance visit, ensuring accurate heat distribution across all pipes, radiators, and heating zones.
Controls verification checklist:
- Calibrate the boiler thermostat and boiler controls for precise temperature response
- Test boiler pressure, system pressure, and water pressure against manufacturer specifications
- Inspect the expansion tank pre-charge pressure, pipe connections, and pump intake
- Verify zone valve operation, pump flow, and radiators for heat distribution accuracy
- Confirm thermocouple readings, pressure relief valve integrity, and expansion tank status across all zones
The technician compiles a maintenance report, boiler inspection report, and service report documenting thermocouple readings, expansion tank status, pump performance, and all recommended repairs.
Common Boiler Problems That Signal the Need for Maintenance
Boiler making noise, boiler leaking, boiler not heating, and boiler losing pressure are the most common boiler problems causing breakdowns, leaks, heating failures, and faults in Lexington, MA homes and commercial buildings.
Common boiler problem warning signs:
- Boiler Making Noise: Banging, gurgling noises from pipes and radiators signal sediment buildup or pump failure.
- Boiler Leaking: A water leak from pipes or expansion tank connections indicates corrosion or valve failure.
- Boiler Not Heating: Cold radiators and uneven heating indicate thermocouple failure or circulator pump failure.
- Boiler Losing Pressure: Pressure loss from the expansion tank or pipes requires immediate maintenance service.
- Thermocouple Failure: A faulty thermocouple causes pilot light out, ignition failure, and boiler not working.
- Heat Exchanger Failure: A cracked heat exchanger causes boiler failure and carbon monoxide risks in older homes.
- Pump Failure: Pump failure stops hot water from reaching radiators and expansion tank heating zones.
- Carbon Monoxide Alert: A triggered CO detector or carbon monoxide detector signals thermocouple or heat exchanger faults.
