Responded to a no-heat call on a 9-year-old Lennox SL280UH gas furnace. Inspected the control cabinet and verified line voltage at the control board, measuring approximately 120.8 VAC, confirming proper power supply to the unit. No visible signs of frost, rust, or component damage were observed during the inspection.

Installed an AprilAire 600 bypass whole-home humidifier on the supply plenum, with a round galvanized duct connection for airflow. Mounted the humidistat control, ran a copper supply line with a saddle valve for water, and routed a clear drain line. Verified all connections are secure and the unit is clean and intact.

Performed a heating tune-up on a Lennox gas furnace under 10 years old, inspecting the burner assembly, flue venting, condensate drainage, and associated components for proper operation. Used a clamp meter to check electrical amperage on the system's motors and components. Furnace and flue piping showed no signs of rust, frost, or damage; unit was left operating normally.

Performed a seasonal tune-up on a single 4-year-old main floor furnace, including inspection of operation and controls and verification of thermostat settings and system response. Replaced the air filter, confirming proper airflow direction, to restore adequate airflow and maintain efficient system performance.

Responded to an install callback on a newly installed furnace reporting cold air output. Inspected the unit's control board, DIP switch settings, low-voltage terminal connections, and wiring harnesses, and verified board configuration and connections were correct with no visible damage, burn marks, or corrosion. Tested the heating cycle to confirm proper operation.

Performed a heating tune-up on one furnace, including inspection of the unit and electrical components and measuring amperage draw on the system's wiring with a digital clamp meter to verify proper operation. Replaced the air filter with a new 20x25x4 pleated filter, installed with the airflow arrow pointed toward the blower motor, restoring proper airflow to the system.

Responded to a no-heat/inadequate heating complaint on a 17-year-old furnace and performed a diagnostic inspection of the unit, including borescope examination of the internal heat exchanger. Imaging revealed rust-colored corrosion and debris along the interior surfaces and seam areas, indicating age-related deterioration that warrants further evaluation. Verified thermostat operation and settings and reviewed findings with the homeowner, including recommendations for the unit's condition and next steps.

Performed a heating tune-up on one 2018 furnace, inspecting the unit and its major components for proper operation. Found the MERV 11 pleated air filter heavily loaded with dust and debris, restricting airflow, and replaced it to restore proper airflow and system efficiency.

Performed a heating tune-up on one furnace, verifying proper operation in heat mode and confirming the thermostat called for heat and the system responded normally. Inspected the Trane whole-house humidifier, including the water supply valve, drain tubing, and humidistat control, and found no visible leaks, corrosion, or damage. Unit is operating normally at completion of service.

Performed a heating tune-up on a 22-year-old Lennox gas furnace, inspecting the burner assembly, gas valve, manifold, blower motor, wiring connections, and flue connection to the plenum. Noted light surface rust on the cabinet casing and dust accumulation on the blower motor, with no other visible damage or anomalies found on the unit.

Performed a heating tune-up on a 10-year-old furnace, inspecting system components and verifying proper operation. Inspected the return air filter and grille, noting dirt and discoloration on the grille louvers, and confirmed the pleated filter was seated correctly. Inspected the installed REME-HALO air purifier mounted on the supply plenum, observing dust and residue on the surrounding ductwork, and confirmed the unit was secured and powered.

Responded to basement lighting that cycled on briefly and then shut off, with no tripped breakers at the panel. Inspected the wall switch and found it hanging loose from the metal box, unsecured, with conductors under strain at the terminals, which likely caused the intermittent loss of connection. Re-terminated the conductors, secured the switch to the box with its mounting strap, and tested for proper, stable operation of the basement lighting.

Diagnosed a no-heat condition on a 9-year-old Lennox furnace and traced the failure to a heavily oxidized, soot-contaminated flame sensor that was preventing flame proving and causing ignition lockout. Removed and cleaned the flame sensor, reinstalled it, and cycled the system through a heating call to verify proper ignition, flame sensing, and sustained heat output.

Responded to a no-heat complaint on a basement-installed furnace that cycled through heat sequence and displayed fault codes E223 and E229 with the blower not running. Inspected the furnace interior and performed electrical diagnostics with a true-RMS clamp meter to check amperage draw on the blower/inducer circuit and associated wiring, evaluating the gas valve and control wiring harness for proper operation. Findings were documented with photos.

Performed a heating tune-up on one 3-year-old furnace, including inspection of the ignition system and cleaning/servicing of the flame sensor, which showed light wear and discoloration but no breakage or corrosion. Verified safe, proper ignition and operation, and applied a furnace service sticker to the unit as requested.

Performed a heating tune-up on a Lennox condensing gas furnace, inspecting the cabinet, PVC intake/exhaust venting, condensate drain line, and ductwork connections for proper installation and condition, with no visible rust, leaks, or damage. Measured blower motor amperage with a true RMS clamp meter, recording 0.26 A, and verified the unit was operating normally.

Returned to address a water heater pilot light repeatedly extinguishing. Inspected the installation in the utility area and performed draft/pressure testing with a digital manometer to evaluate venting and combustion air conditions as a potential cause of the pilot outage. Verified readings and system operation, and documented the findings with photos.

Responded to a reported sewer vent pipe backup and inspected the exterior sewer cleanout and surrounding drain line, where wastewater was surfacing and running across the pavement. Evaluated the main sewer line for blockage and restricted flow, with the cracked, deteriorated pavement around the access cover noted as a possible contributing factor. Documented site conditions with photos for follow-up recommendations.

Performed a preventive maintenance tune-up on the furnace, inspecting the unit and verifying proper operation through a full heating cycle. Used a digital clamp meter to measure electrical draw and confirm components were operating within normal amperage range, and verified the thermostat was functioning and communicating correctly with the system.

Performed annual heating tune-up on two gas furnace systems, including inspection of the burner assembly, heat exchanger, ignition components, electrical connections, and safety controls, along with verification of proper combustion, airflow, and thermostat operation. Inspected the condensate drain piping and the Aprilaire whole-home humidifier, finding no visible damage, and noted residue staining on the floor near the condensate drain that should be monitored for leaks. Both systems were operating properly at completion.
