Performed a seasonal heating tune-up on a 9-year-old gas furnace that was operating properly at arrival. Inspected the burner assembly and flame sensor, and verified a steady blue ignition flame across all burners during the heating cycle, indicating proper combustion. Measured supply air temperature with a digital thermometer to confirm normal system operation, with no signs of corrosion or damage observed.

Diagnosed a faulty GFCI receptacle on the screened porch circuit, inspected the main breaker panel, and replaced the defective 20-amp GFCI outlet with a new unit. Verified proper wiring termination, secured the wall plate, and confirmed correct test/reset operation and circuit function.

Performed a heating tune-up on one furnace, including electrical verification with a true RMS clamp meter (measured 1.39 A AC draw on the monitored circuit) and operational testing of the system through the Emerson digital thermostat. Verified the unit responds to a call for heat, with the thermostat indicating "Heat On Auxiliary" at a 74° setpoint against a 64° room temperature. The furnace was left operating, and no damage, rust, or abnormal conditions were noted.

Performed a heating tune-up on a one-year-old furnace, inspecting the unit and its components for proper operation. Verified the air filter (Filterbuy pleated) was clean and in good condition with no discoloration or damage, and inspected the General 1042L power humidifier, confirming the water supply line, solenoid valve, wiring connections, and drain tube were intact with no visible damage or corrosion. System was found in good working order with no repairs required.

Installed a new 40-gallon tall gas tank-style water heater under permit 26PLU-20961, connecting it to the existing copper supply lines with isolation ball valves and soldered fittings. Verified secure connections, with no leaks or visible damage to piping or fittings, and applied the required permit sticker.

Performed a heating tune-up on a 7-year-old Amana gas furnace, including removal and replacement of two heavily soiled 14x20x1 pleated air filters to restore proper airflow. Inspected the flue venting, gas line and shutoff valve, electrical connections, and condensate drain line, and cleared the floor drain area to ensure proper drainage and safe, efficient operation.

Installed a 600M bypass humidifier on the furnace supply plenum, using 6" round duct and a 90° elbow to connect the unit. Ran a clear drain line from the humidifier to the floor drain and confirmed the system is ready for heating season operation.

Responded to a no-heat call on a 7-year-old furnace that was calling for heat but failing to engage. Inspection of the flue/vent assembly revealed heavily corroded and rusted vent collar with flaking mineral deposits, along with debris and bird nesting material obstructing the open side of the flue passage, which can impede proper draft and trigger safety lockouts. Documented findings with photos and recommended clearing the obstruction and repair or replacement of the corroded flue components to restore safe, reliable operation.

Responded to a reported natural gas odor at a newly installed furnace and inspected the gas piping assembly, including the shutoff valve, black iron fittings, and threaded joints at the unit's supply connection. Leak-tested the connections and identified the source of the leak at a threaded joint showing sealant residue. Disassembled, re-sealed with approved pipe thread sealant, and re-tightened the joint, then verified the repair was leak-free before restoring gas service and returning the system to normal operation.

Responded to a no-heat call on a 3-year-old Daikin gas furnace where the thermostat was displaying a sensor error. Inspected the thermostat and furnace, including the condensate drain assembly, gas supply, and flue connections, and diagnosed the fault affecting heat operation. Restored the system to operation and verified heating performance and thermostat communication.

Responded to a no-heat call on a gas furnace where the blower operated but no heat was produced. Inspected the burner compartment, Honeywell gas valve, manifold, and inducer assembly, and found sooty, discolored fittings and heavy dust and debris buildup indicating combustion and airflow issues. Verified wiring harness connections and documented the system condition for further evaluation and recommended repairs.

Responded to a no-cool call on a single heat pump system following a power loss. Thermostat notifications showed an "OU Low Pressure Switch Strikes Lockout" alert (code 411) and a "Must Program Unit Capacity For Device" alert (code 34), indicating the outdoor unit had locked out on low-pressure switch faults and the control required unit capacity reconfiguration after the power interruption. Diagnosed the lockout condition and documented the active fault codes for system restoration.

Performed a heating tune-up on one gas furnace system under 10 years old. Inspected the return air filter and found it heavily loaded with dust and lint, seated askew and bent in the filter slot, with significant debris buildup in the return duct opening and on the grille louvers. Documented the condition of the filter and return air grille, and recommended filter replacement and cleaning of the return grille to restore proper airflow and system efficiency.
