Performed a heating tune-up on the system, including inspection of the 16x25x1 return air filter, which was heavily loaded with dust and debris and clogged, restricting airflow. Inspected the bypass whole-house humidifier and found the evaporator pad aged with mineral buildup, indicating it needs replacement; confirmed the water supply line, drain tube, and seasonal damper positioning (summer/winter) are in place. Completed the system inspection and renewed the service membership.

Performed a seasonal heating tune-up on one Lennox upright gas furnace, including inspection of the unit, venting, and gas connections for proper operation. Found the pleated return air filter heavily loaded with dust and debris, which restricts airflow and reduces system efficiency, and recommended replacement. The furnace was left operating normally at the completion of the service.

Performed a seasonal tune-up on a 2-year-old Lennox gas furnace, inspecting the inducer motor, pressure switch and hose, gas valve and piping, burner and heat exchanger area, and control wiring and connections. Verified electrical operation with a clamp meter, checked the condensate drain and vent piping, and confirmed all components were in good working order with no visible damage, rust, or leaks. System was reassembled and left operating normally.

Performed a seasonal tune-up on a 15-year-old basement furnace, including inspection of the system and its air filter, which was found clean, intact, and free of debris. Used a handheld electronic meter to test for carbon monoxide at the unit, with a reading of 0 indicating no CO present. Furnace operation was verified, and no deficiencies were noted.

Inspected the boiler piping in response to a reported leak and found heavy surface corrosion and mineral buildup on the aged black iron supply and return piping, threaded fittings, tee and union connections, and the gate valve. Evaluated the affected joints as the likely source of the weeping and documented the condition of the system with photos for repair recommendations.

Installed a 50-gallon gas tall water heater in residential utility room. Completed all gas line connections, plumbing hookups, and venting installation per manufacturer specifications and local code requirements. Permit obtained through City of University City for the installation.

Completed annual preventive maintenance on a 3-year-old residential boiler system located in basement mechanical room. Performed comprehensive tune-up including inspection of all electrical components, control boards, and safety systems. Verified proper operation of burner assembly, tested all safety controls, checked venting system integrity, and inspected copper piping connections and brass valves throughout the hydronic heating system. All components found operating within normal parameters with no issues identified. System returned to full operational status.

Completed comprehensive heating tune-up on basement furnace unit. Performed diagnostic testing including electrical measurements showing 603 reading on multimeter, inspected blower assembly and motor components, checked all wire connections and safety controls, and examined 16x25 filter/ductwork area. All systems operating within normal parameters upon completion.

Completed comprehensive cooling maintenance on two Lennox HVAC systems: one basement unit and one attic unit, both approximately 9 years old with two outdoor condensing units. Performed full AC tune-up protocol on both systems including filter inspection and replacement, blower motor assembly evaluation, and verification of proper airflow through squirrel cage blower wheels. Both systems tested and confirmed operational with no deficiencies noted.

Conducted return site visit to assess switch location and evaluate mortar/concrete residue on paver surfaces for potential removal options. Documented existing conditions with photographs for follow-up remediation planning.

Returned to property to replace incorrectly sized expansion tank that was installed during previous boiler installation. Removed undersized expansion tank from system without draining boiler and installed proper replacement unit. System tested and confirmed operational with correct expansion tank now in place.

Responded to no cooling call on 4-year-old Lennox model 13ACXN03D-230-26 outdoor condensing unit. Upon arrival, confirmed unit was blowing warm air with no cooling capacity. Performed diagnostic evaluation of system components including capacitor inspection and electrical connections. Assessed condenser coil condition and verified proper power supply to unit. Completed necessary repairs to restore cooling operation and tested system for proper functionality before departure.

Responded to report of heat kit tripping breaker on basement AC unit. Inspected electrical panel and verified 30-amp breaker serving the air handler was experiencing overload condition. Examined thermostat operation showing cooling mode active with 75°F current temperature and 79°F setpoint. Identified heat kit as source of electrical fault causing breaker trips. Documented panel labeling indicating "Air Handler" circuit and photographed thermostat settings and breaker configuration for reference.

Responded to recurring toilet backup in main bathroom following multiple previous service visits. Investigated persistent clogging issue, reviewed warranty coverage onsite, and documented conditions. Photographed toilet and surrounding area to assess drainage concerns and identify potential underlying causes requiring further remediation.

Completed scheduled boiler tune-up and safety inspection. Verified proper operation of pressure and temperature gauges, confirming readings within normal parameters. Inspected pressure relief valve, copper piping connections, and all brass fittings for signs of leaks or corrosion. Noted evidence of moisture on concrete floor near expansion tank, documented conditions with photos for customer awareness. All components functioning properly at time of service completion.

Returned to property during morning hours to conduct attic inspection that could not be completed during previous evening visit due to excessive heat conditions. Performed thorough evaluation of attic insulation and ductwork system to determine root cause of cooling issues. Found deteriorated and compressed insulation with uneven coverage throughout attic space, along with flexible HVAC ductwork requiring assessment. Documented conditions with photographs for further analysis and repair recommendations.

# HVAC Tune-Up Completed Performed comprehensive tune-up on a 10-year-old furnace unit located in basement. Inspected and evaluated heavily soiled air filter showing significant dust and particulate accumulation; filter displayed visible discoloration indicating extended use period. Conducted thorough examination of heat exchanger assembly, electrical connections, and wiring components including capacitor and terminal connections. All system components were inspected for proper operation and safety compliance per manufacturer specifications.

Returned to property to address PVC termination penetration through exterior wall. Removed deteriorated mortar around dual PVC pipe elbows and resealed penetrations with fresh mortar to ensure proper weatherproofing and structural integrity. Unit confirmed operational upon completion.

Responded to no cooling complaint with ice formation on unit U10 located at back of home. Upon arrival, instructed occupant to turn off AC unit while leaving fan in ON position to allow ice to thaw. Inspected electrical control panel and contactor assembly, documenting existing wiring connections and component conditions. Observed aged HVAC system with visible wear on electrical enclosure and components, including oxidation on terminal connections. Capacitor and contactor assembly inspected and photographed for service records. System shows signs of extended service life with weathered components throughout electrical compartment.
