Inspected the control compartment, including the Emerson integrated control board, low-voltage transformer, wiring harness connections, and terminal block, and noted moisture and residue present in the cabinet. Diagnosed the fault using the board's flash code and system operation, and performed the necessary repair to restore the furnace to normal heating operation.

Performed a complete furnace and humidifier tune-up on a 12-year-old system, including inspection of the furnace components and humidifier assembly. Borescope inspection revealed frost buildup and a visible crack or seam on an internal surface, which was documented for evaluation. Inspected the flame sensor/igniter assembly and found the metal rod tarnished with carbon buildup, indicating wear that may affect ignition reliability.

Performed a seasonal tune-up on an 8+ year-old gas furnace and AC system, inspecting the furnace, air handler, humidifier, and condensate/drain lines and checking for proper operation. Found the hot surface igniter showing hairline cracks and staining, with heavy rust, corrosion, and soot buildup on the burner plate and base, indicating aged components that should be monitored or replaced to ensure reliable ignition and safe operation.

Installed a condensate drain line on the exhaust/intake PVC venting to eliminate excess condensation accumulation. Routed and secured the drain assembly with a cap and flexible tubing, then verified proper drainage with no leaks observed at the connections.

Performed a complete furnace tune-up on an 8-year-old gas furnace, including inspection and cleaning of the flame sensor, which showed discoloration and wear, and verification of gas valve, manifold connections, pressure switch, condensate drain, and wiring integrity. Inspected the Trane CleanEffects air cleaner for proper operation and confirmed the system was functioning correctly at completion.

Performed a complete annual tune-up on the Trane gas furnace, including inspection of the burner assembly, heat exchanger, flue and venting, condensate drain line, and gas and electrical connections, and verified safe, proper operation through a full heat cycle. Serviced the whole-house humidifier and replaced the system air filter. No visible rust, frost, leaks, or damage was observed, and the system is operating normally.

Replaced the main zoning control panel on the boiler system with a new Caleffi multi-zone panel. Disconnected and relabeled the thermostat (T-STAT 2–6), zone pump, and motor wiring, then reterminated all connections to the new board and verified DIP switch settings for master, exercise, priority, and aux functions. Restored power and confirmed proper operation of all zones.

Performed a complete furnace tune-up on a 6-year-old gas furnace, including inspection of the burner assembly, heat exchanger, blower components, flue venting, and safety controls, and replaced the air filter with the specified 213 size. Verified proper ignition, combustion operation, and airflow, with the system running normally at completion. Also checked the adjacent gas water heater, flue connection, and plumbing, noting no visible rust, leaks, or damage.

Performed a callback inspection to reassess reported rust concerns on the furnace and water heater. Surface corrosion was observed on the gas supply piping and fittings within the furnace cabinet, along with minor discoloration at the PVC vent and condensate piping joints; no active leaks, structural deterioration, or operational concerns were identified, and the condition appears cosmetic in nature. Documented all findings with photos for the service record.

Performed a full maintenance tune-up on a 7-year-old gas furnace, including removal and inspection of the burner assembly and cleaning of the burner and ignition components. Inspected the heat exchanger openings and found them clean, with no visible cracking, rust, or corrosion, and verified the flame sensor/ignitor was properly seated. Confirmed safe, normal furnace operation and left the system running properly.

Responded to a no-heat call on a hydronic boiler system with no indicator lights on the six-zone Caleffi ZVR106 zone relay panel. Inspected the zone relay enclosure and verified the thermostat-to-zone wiring and terminal connections, documenting zone assignments for each thermostat group to support diagnosis and future service.

Performed a scheduled diagnostic on a Trane gas furnace reported as not heating. Opened the cabinet and inspected the burner assembly, heat exchanger, gas valve, inducer motor, pressure switches and tubing, flue/vent connections, wiring harnesses, transformer, relay, and control board. Burner flame was present, with no visible corrosion, frost, or physical damage to components, and the unit's safety circuits and venting were reviewed for proper operation.

Performed a furnace tune-up on a 5+ year-old unit, including inspection of the blower assembly, wiring harness connections, motor connector, and cabinet insulation, with no signs of damage, rust, or frost observed. Verified blower motor operation with a true RMS clamp meter, measuring 0.41 A amperage draw during operation. Equipment was found in good working condition.

Performed a comprehensive tune-up on the furnace, including inspection of the burner compartment, gas valve assembly, wiring connections, and inducer components, with electrical readings taken using a clamp meter to verify proper operation. Serviced the humidifier and replaced the semi-annual filter. Noted frost and moisture accumulation on the upper supply ductwork and adjacent surfaces, indicating a condensation issue that should be evaluated further.

Performed annual tune-up on a 9-year-old furnace and humidifier, including inspection of the cabinet and ductwork, a carbon monoxide test with a calibrated analyzer (0 ppm recorded), and inspection of the air filter, which was found clean and in good condition. Serviced the humidifier and installed a new #35 pad, and the system was left operating properly.
