Performed a Comfort Plan clean and check on one air conditioning system and air handler, including electrical measurements at the control circuit board, transformer, blower capacitor, and wiring using a TRMS clamp meter. Inspected the blower assembly, evaporator coil, copper refrigerant line brazed joints, and ductwork, finding no frost, rust, or visible damage, though light dust and insulation debris were present in the cabinet. Also evaluated the in-floor radiant heating system at the customer's request; any further diagnostics or system flushing/bleeding would be performed as a separate service.

Performed a clean and check on the furnace, rooftop unit, and water heater. On the furnace, inspected the burner assembly and verified a proper blue flame pattern, checked the gas valve, pressure switch, and wiring connections, and cleaned and inspected the condensate drain and trap components, finding no rust, ice, or breakage. System was left operational with all components inspected and functioning.

Performed a furnace tune-up on one system, including inspection of the control board, wiring harnesses, and terminal connections, with no signs of corrosion, burn marks, or damage found. Took temperature readings at the ductwork and air handler cabinet with a digital thermometer to verify proper system operation.

Performed annual Comfort Plan clean and check on the furnace, humidifier, and water heater, including inspection of the Aprilaire humidity control mounted on the supply duct and verification of its setpoint dial operation. Checked temperature at the insulated refrigerant line and adjacent panel with a pocket thermometer (69.6°F), confirming no frost, rust, or visible damage. System operation was verified at completion.

Responded to a no-heat call with a thermostat display showing no power; inspected the control compartment wiring and 24V low-voltage supply and found the control transformer secondary connections (red/yellow) with discolored, heat-affected insulation, indicating a failed or overloaded transformer circuit causing loss of control power. The integrated furnace control board shows an all-segments-lit "888" display, consistent with a power or control fault. Recommend replacing the transformer and repairing the affected terminations, and checking for a low-voltage short before restoring thermostat power.

Responded to a customer-reported heating issue and inspected the attic-mounted horizontal gas furnace, including the PVC vent and intake piping, condensate drain, zoning control board, and ductwork connections. Performed combustion safety testing with a handheld CO analyzer at the unit, and noted moisture staining on the plywood near the condensate drain piping, indicating past leakage that should be monitored. Documented all equipment information for the service record.

Performed a Comfort Plan clean and check on the gas furnace and water heater. Inspected the furnace's inducer blower assembly, pressure switch and tubing, gas valve and piping, burner assembly, and wiring connections, finding all components intact. Used a borescope camera to visually inspect internal passages and confirm the system's condition.

Performed annual heating maintenance tune-up on two gas furnaces, including inspection of the inducer blower assembly, pressure switch, gas valve, burner assembly, and wiring, along with a check of the whole-home humidifier and the water heater. All equipment was operating normally with no visible damage, rust, or frost observed.

Performed a comfort plan clean and check on one system, covering the furnace, humidifier, and gas water heater. Inspected and tested the furnace and humidifier components, verifying proper operation and measuring electrical current draw with a true RMS clamp meter. Inspected the Rheem gas water heater, including the vent connection, gas control valve, and supply and relief piping, and noted mineral buildup on a component during testing.

Responded to a service call for a furnace reported as having issues, with a routine check requested. Inspected the thermostat (set at 83°F, calling for heat) and the air handler blower motor, which showed heavy dust and lint buildup on the motor housing, vent openings, brackets, and surrounding cabinet surfaces. Documented the blower assembly condition and furnace operation for evaluation and recommended maintenance.

Performed a Comfort Plan clean and check on a Lennox gas furnace, inspecting the inducer motor, pressure switch, wiring, and control components, and cleaning accumulated dust and debris from the cabinet interior. Serviced the humidifier with a new Hydrocore pad and installed a 16x25x4 media filter. Verified safe operation with a combustion safety check using a handheld carbon monoxide analyzer, which recorded 0 PPM.

Performed a comfort plan clean and check on the furnace, including a combustion safety evaluation with a handheld carbon monoxide analyzer and a visual inspection of the heat exchanger using an inspection camera. The heat exchanger fins showed minor debris along the edges, and the system was verified to be operating safely.

Performed a comfort plan clean and check on the furnace, humidifier, and tankless water heater. Inspected the furnace cabinet, gas valve, pressure switch, wiring harness, control board, and blower assembly, and removed accumulated dust and debris from the interior. Replaced the mineral-stained humidifier evaporator pad with a new pad and verified proper operation of the system.

Performed an in-home evaluation of the basement Rheem Criterion gas furnace for replacement and potential add-on air conditioning. Inspected the unit, galvanized plenum, flue venting, gas piping, and surrounding ductwork, documenting equipment condition with photos, including discoloration near the flue connection at the plenum. Assessed the installation for a replacement furnace estimate.

Diagnosed a tankless water heater displaying Error Code 12 (flame failure/no flame detection), a recurring fault. Inspected the burner assembly, flame rod, and flame sensor circuit, serviced the ignition and flame-sensing components, and verified a stable flame signal. Confirmed proper operation with the unit firing and delivering hot water at the set temperature of 135°F.

Relit the pilot on the gas space heater and confirmed ignition and stable burner operation, with a steady blue flame observed through the viewing port. Inspected the gas valve assembly and supply piping, noting heavy dust accumulation, surface corrosion on the iron elbow fitting, and deteriorated pipe coating, and recommended monitoring the connection and cleaning or servicing the unit to maintain safe, reliable operation.
