Replaced a 40-gallon atmospheric-vent gas tank water heater and a second 50-gallon gas unit, reconnecting the gas supply, water lines with isolation valves, and the draft hood and galvanized flue venting. Inspected the surrounding piping and noted deteriorated fiberglass pipe insulation, oxidized copper fittings at the tank connections, and an aged iron gate valve, which should be addressed to maintain system efficiency and reliability.
Performed a tune-up on a Lennox gas furnace (approx. 2 years old), including inspection of the control board, wiring, and blower compartment, with no damage, corrosion, or frost observed. Verified combustion performance with a flue gas analyzer (O2 7.5%, CO 15 ppm) and confirmed the unit was operating properly with no issues found.
Performed a fall heating tune-up on a 7-year-old Goodman system, including electrical testing with a True RMS clamp meter and inspection of the integrated furnace control board and low-voltage terminal connections (EAC, HUM, and fault circuits). Noted dense, loosely routed control wiring within the cabinet and verified connections for secure termination. System operation was checked and confirmed ready for the heating season.
Performed scheduled heating maintenance on the gas-fired water heater/heating appliance, including a combustion analysis with a flue gas analyzer showing stack temperature of 307.3°F, O2 at 8.0%, CO at 15 ppm (air-free 24 ppm), CO2 at 7.29%, and combustion efficiency of 82.8%, with all readings within acceptable operating range. Conducted a borescope inspection of the vent/flue passage, which showed a thin seam or crack in the interior surface that should be monitored, and no blockage was observed.
Responded to a no-heat call on the combi boiler serving Unit 1 and inspected the boiler, circulator pump, expansion tank, and associated hydronic piping and valves. Diagnosed and addressed the cause of the heat loss, then verified proper system operation and heat delivery to the unit. Noted surface corrosion on the aging black iron piping and fittings for future monitoring.
Performed annual heating system maintenance and combustion analysis using a Testo 310 analyzer, recording flue gas readings of 8.2–8.4% O2, 10 ppm CO, and 83.2% combustion efficiency. All readings were within acceptable operating parameters, confirming safe and efficient furnace operation with no CO concerns, frost, rust, or visible damage noted.
Performed annual heating system maintenance and inspection on the furnace, including electrical diagnostics with a true RMS multimeter to verify component resistance and wiring integrity within the air handler cabinet. Inspected the condensate drain/pump assembly, blower and inducer housing, and associated low-voltage and line-voltage connections, with no visible damage, rust, or leaks noted.
Performed a club enrollment maintenance visit on a Carrier gas furnace equipped with an Aprilaire air cleaner, including a combustion analysis with a Testo 310 analyzer that recorded 8.6% O₂ and 9 ppm CO, indicating clean, safe combustion. Inspected the condensate drain piping, venting, and surrounding equipment and found no visible damage, rust, or leaks, with the system operating normally at the conclusion of the visit.
Performed an on-site replacement evaluation of the existing furnace and air conditioning system, both approximately 20 years old, including inspection of the furnace and associated galvanized ductwork in the utility space. Documented the furnace control board and low-voltage thermostat wiring at the terminal block (R, W, G, C), noting terminal wear and dust accumulation, to support equipment replacement sizing and quoting for both systems.
Performed seasonal HVAC maintenance and inspected the furnace flame sensor, with no frost, rust, or visible damage noted on the sensor or surrounding equipment. Verified system electrical operation with a true RMS digital clamp meter, then renewed the maintenance club visit for the equipment.
Performed annual heating maintenance on the gas furnace, including inspection of the burner compartment, hot surface igniter/flame sensor, gas valve, and wiring connections. Conducted combustion analysis with a Testo 310 analyzer, recording O₂ at 6.9% and CO at 58 ppm to verify safe, efficient operation of the appliance.
Diagnosed and repaired a leaking kitchen faucet on an oil-rubbed bronze gooseneck fixture by servicing the spout collar and handle assembly, replacing worn seals and cleaning mineral deposits to restore a watertight seal. Also addressed a hissing toilet by inspecting the fill valve and tank components, correcting the internal leak, and verifying proper shutoff and operation of both fixtures.
Returned to complete the sold repair, replacing the backflow preventer and a 6' section of galvanized water line at the mechanical room supply piping, including reconnection to the existing meter and isolation valves. Verified the boiler control module was operating normally at a 180° setpoint reading, with no fault indications present.
Performed seasonal preventive maintenance on a seven-year-old outdoor AC system during a routine tune-up; the unit was operating properly with no reported issues or symptoms.

No visible rust, frost, or damage was observed on the inspected panel surfaces, and the system was left in normal working condition.
Performed a furnace tune-up, including inspection and testing of key electrical components. Measured the capacitance of the motor run capacitor with a true RMS clamp meter (12.69 µF) to verify it operates within specification, and used a K-type thermocouple to check system temperatures. Equipment was left operating properly.
Returned to complete the previously sold repair, replacing the Wye connector in the combined boiler and water heater vent system. Installed a new galvanized Wye fitting with secured, clamped joints and properly supported connections to the water heater and boiler vent runs. Sealed the vent pipe wall penetration to restore a tight, finished connection and ensure proper venting of combustion gases.
Responded to a no-heat call on a 5-year-old Heil furnace and inspected the control board, low-voltage wiring, transformer, and 3-amp blade fuse for faults.

Restored furnace operation and confirmed normal heating cycle.
Performed seasonal heating maintenance on the furnace, including inspection of the control compartment, low-voltage and line-voltage wiring, transformer, control board connections, and pressure switch/inducer assembly. Electrical measurements were taken with a true RMS clamp meter to verify proper operation of the system. Noted tangled wiring with loose conductor ends and wire-nut connections in the control compartment that should be monitored for secure termination and proper routing.
