Inspected control boards and electrical panels, verified wiring connections and terminal blocks were secure. Checked LCD display readings on circuit boards. Documented condition of heat exchanger coils showing age-related deterioration with mineral deposits and white residue buildup from condensation. Photographed affected components including finned coil surfaces, U-bend copper tubing, and electrical control systems for service records.

Responded to service call for two radiators remaining warm despite heating system being turned off, a recurring issue previously addressed. Verified all three thermostats were properly set to no heat mode and inspected the hydronic heating system including boiler unit, circulator pump, zone valves, and piping connections to identify potential causes of unwanted heat transfer.

Completed preventive maintenance agreement service on central air conditioning system and Unico air handler. Inspected squirrel cage blower assembly, noting dust and debris accumulation on blades and housing, which is typical of normal operation. Replaced air filter with new pleated media filter to maintain proper airflow and system efficiency.

Performed preventive maintenance inspection on multi-condenser HVAC system under agreement terms. Inspected blower wheel assembly, verified proper operation and cleanliness of centrifugal fan components, and documented normal condition of evaporator coil with expected condensation present during cooling operation. Temperature measurements confirmed system operating within manufacturer specifications.

Completed preventive maintenance agreement service on dual condenser system. Inspected air handler unit in attic space with spray foam insulation, verified proper operation and documented equipment condition. Confirmed thermostat functionality on Honeywell ProSeries unit displaying proper cooling mode and fan settings.

Completed comprehensive maintenance agreement inspection on 6-year-old air conditioning unit and 4-year-old furnace. Performed thorough system evaluation including visual inspection of equipment components, verified operational status of control boards and safety devices, and documented equipment condition with photographic records. All systems found operating within normal parameters with no immediate service needs identified.

Completed preventive maintenance on condenser unit and replaced 20x25x1 air filter per maintenance agreement terms. Inspected water heater, plumbing connections, and associated mechanical equipment in utility room, documenting existing conditions including aged water meters with visible corrosion on metal components and PVC piping connections. All systems operational upon completion of service visit.

Responded to warranty recall for exposed wire concern on 2024 AC system. Upon inspection, located and assessed exposed wiring at ceiling-mounted fixture using detection equipment. Examined exterior refrigerant line set and electrical conduit routing along building exterior to verify proper installation and identify any additional exposed conductors. Secured and protected all exposed wiring per code requirements to ensure safe operation and system integrity.

Returned to site to complete warranty repair on Unico air handler control system. Successfully installed replacement circuit board in the air handler unit, connecting all necessary wiring including power leads, control wires, and sensor connections to appropriate terminals. Removed failed control board from equipment and properly documented the defective component for warranty processing. Verified all electrical connections were secure and system wiring was correctly terminated to the new board. Tested air handler operation to confirm proper functionality following board replacement.
