Radiant In-Floor Maintenance & Tune-Up

When you schedule maintenance, we ask about your system’s age, any comfort issues you’ve noticed, and whether you’ve had prior service. We confirm that parts are in stock for your specific system (boiler brand, pump type, valve configuration) so we complete everything in one visit. Returning customers’ systems are familiar to us — we reference prior inspection reports and compare this year’s findings to last year’s to spot trends early.

• Review your system history and prior maintenance reports
• Confirm boiler model, pump type, and zone configuration
• Stock necessary parts, filters, and tools before arrival
• Schedule appropriate time based on your system’s complexity and size
• Brief discussion of any comfort concerns or operational changes since last season

Our technician arrives and begins with a cold system inspection. We visually check the boiler, pump, zone valves, manifold, and expansion tank for leaks, corrosion, or visible wear. We measure system pressure (should be 25–35 PSI at rest) — low pressure signals a slow leak that needs attention. We verify the boiler fires up, monitor initial water temperature rise, and confirm circulation pressure builds to normal levels. We also test zone valve response by setting the thermostat to call for heat and confirming each zone independently opens and delivers warmth.

• Visual inspection of all components for leaks, corrosion, or visible damage
• System pressure measurement and documentation (trending year-to-year)
• Boiler cold-start test and ignition sequence verification
• Zone valve response testing (each zone independently cycles)
• Circulation pump pressure and flow confirmation
• Thermostat communication and setpoint accuracy check

Water is the lifeblood of a radiant system. We draw a sample from your system and test it for inhibitor concentration, pH, and conductivity. Proper inhibitor protects copper, steel, and aluminum components from rust and corrosion. If inhibitor is depleted or pH has shifted, we flush and treat the water to restore full protection. This step alone helps prevent costly future component replacements.

• Water sample extraction using sterile techniques
• Lab or on-site testing for inhibitor concentration, pH, and conductivity
• Assessment of water color and clarity (dark water suggests corrosion)
• Flush and treatment if inhibitor is depleted or chemistry is off-range
• Documentation of water chemistry results for your records and trend tracking

The boiler is the heart of your heating system. We inspect the combustion chamber, test flame sensing, check the flue for blockage, and measure exhaust gas temperature and combustion efficiency. We also verify all safety controls — high-temperature shutoff, pressure relief valve function, and gas valve operation. A clean, efficient boiler runs quieter, wastes less fuel, and is safer. We clean or replace filters, adjust water temperature setpoints, and ensure the mixing valve is functioning properly.

• Combustion chamber visual inspection (looking for soot or corrosion)
• Flame sensor and gas valve electrical continuity testing
• Flue gas analysis (carbon dioxide, oxygen, temperature measurement)
• Combustion efficiency calculation and comparison to manufacturer specs
• Filter inspection and replacement if needed
• Thermostatic mixing valve temperature verification and adjustment
• Expansion tank pressure testing and adjustment
• Safety control verification (high-limit shutdown, pressure relief)

We use a thermal imaging camera to verify that all zones are delivering even heat to your floors. We set each zone to a comfortable setpoint and observe floor surface temperatures — they should be consistent across the room. Uneven temperatures may indicate a zone valve problem, air in the lines, or a design issue that needs attention. We also run the system through all operating modes, verify thermostat scheduling works as expected, and confirm you can independently control each zone. Finally, we review the maintenance report with you, discuss findings, and recommend any follow-up service.

• Thermal imaging of floors in each zone to verify even warmth distribution
• Zone-by-zone verification that thermostats independently control temperature
• Smart thermostat or programmable thermostat schedule verification
• Circulation noise assessment (should be silent or very quiet)
• Final system pressure and temperature readings
• Documentation of all findings and comparison to prior-year results
• Recommendations for any follow-up service or component replacement needed
• Discussion of seasonal adjustments (setpoint changes for summer/winter)
