Responded to service call for electrical panel evaluation and replacement. Upon inspection, found existing panel box mounted on wooden framing in basement utility area with multiple circuit breakers showing signs of age and potential capacity limitations. Successfully replaced outdated electrical panel with new panel box, ensuring proper mounting to structural framing and maintaining code-compliant clearances. Reorganized and secured all incoming electrical cables, including black, white, and yellow conductors, ensuring proper connections to new breaker configuration. Verified all circuits were properly labeled and functioning, with adequate capacity for current and future electrical loads throughout the residence.

Completed comprehensive spring maintenance inspection on three residential air conditioning systems: one 1-year-old unit and two 15-year-old units located in basement and attic spaces. Performed Gold AC Tune-Up protocol on all three systems, including filter inspection, refrigerant level verification, electrical connection testing, condenser coil cleaning, fan motor lubrication, and thermostat calibration. All outdoor condensing units inspected and photographed, with older units showing normal wear consistent with 15 years of operation but maintaining operational integrity. Systems tested and confirmed operational for cooling season.

Completed Gold AC Inspection on a Lennox outdoor condensing unit less than one year old. Performed comprehensive system evaluation including visual inspection of exterior cabinet, coil condition, and proper unit placement on vibration pad. Verified thermostat/humidistat control functionality with AprilAire equipment located at air handler in basement. Confirmed system operational status with no deficiencies noted. Unit properly positioned on gravel base with adequate clearance from structure and landscaping. All components functioning within normal parameters for recently installed equipment.

Responded to water leak complaint on boiler union pipe that was previously replaced in January. Upon inspection, identified active leak at union connection on boiler piping system. Disassembled leaking union joint, cleaned and inspected threads and sealing surfaces for damage or debris. Replaced union gasket and applied appropriate pipe thread sealant to ensure proper seal. Reassembled union connection with correct torque specifications. Pressurized system and conducted thorough leak test to verify repair integrity. No additional leaks detected at union or surrounding connections. System restored to normal operation.

# HVAC Maintenance - Gold AC Inspection Completed comprehensive Gold-level air conditioning inspection on two outdoor condensing units, both under 10 years of age. Performed thorough visual assessment, operational testing, and diagnostic evaluation of both systems. Documented equipment condition through photographic records showing both units positioned on concrete pads against exterior building wall with proper clearances maintained. ## Inspection Activities Performed **Unit 1 Assessment:** - Inspected outdoor condensing unit with light gray metal cabinet and vertical louvered ventilation panels - Verified protective fan grille integrity and proper installation - Assessed concrete pad condition, noting weathering and surface deterioration with moss/algae growth - Checked refrigerant line connections and electrical terminations - Evaluated unit positioning and clearances from surrounding structures including wooden trim and lattice screening - Confirmed adequate drainage around unit

Conducted on-site assessment for non-functional central air conditioning system and inadequate cooling in upstairs area of century-old residential property. Evaluated existing electrical panel capacity and upstairs living space configuration to provide comprehensive estimate for replacement central A/C unit and supplemental ductless mini-split system installation to address multi-level cooling deficiencies.

Performed system start-up and commissioning on newly installed basement evaporator coil and outdoor condensing unit. Connected digital manifold gauges to service ports and verified refrigerant pressures, subcooling, and superheat readings to ensure proper system charge and operation within manufacturer specifications.

Performed comprehensive inspection and tune-up on 3-year-old ductless mini-split system with four indoor air handling units located throughout the home and outdoor condenser unit mounted on exterior brick wall. Evaluated all four indoor heads for operational efficiency and provided detailed quote for deep cleaning service of evaporator coils and blower wheels. Inspected outdoor condenser unit, verified refrigerant line connections, checked electrical connections at all components, and confirmed proper system operation across all zones.

Completed new installation of drop-in air conditioning system in attic space with no pre-existing HVAC infrastructure. Installed electrical panel with circuit breakers, ran flexible metal conduit to junction box, and established all necessary electrical connections to support the new AC unit. Documentation photos captured for record-keeping purposes.

Responded to a laundry room service call to address dryer venting concerns. Upon inspection, identified improper dryer vent configuration with flexible aluminum ducting and inadequate routing from the appliance to the exterior termination point. Accessed the ceiling cavity above the laundry area to assess the existing vent pathway and structural limitations. Documented the current installation showing the LG front-loading washing machine placement, existing wall-mounted vent components, and the flexible white ribbed ducting material. Photographed the overhead framing, joists, and existing utility lines to plan proper vent routing that complies with code requirements for rigid or semi-rigid metallic ductwork with minimal bends and appropriate clearances from electrical wiring and insulation. Provided recommendations for correcting the ventilation system to ensure proper airflow, reduce lint accumulation risk, and improve dryer efficiency and safety.

Conducted plumbing estimate for replacement of old capped copper gas line serving dryer location in basement of century-old single-family residence. Assessment included evaluation of existing gas piping from spring shutoff valve to dryer termination point, documentation of current system condition, and determination of scope for complete line replacement to restore safe gas supply to appliance.

Performed diagnostic evaluation of over-the-range microwave ventilation system in kitchen. Found unit operating in recirculation mode with exhaust air venting back into space behind microwave rather than being properly ducted to building exterior through available exterior wall. Assessed existing installation configuration, cabinet arrangement, and potential exterior venting pathway to provide recommendations for converting recirculating system to proper exterior exhaust ventilation.

Performed heating system tune-up with comprehensive inspection of burner assembly and control components. Identified severely soiled air filter requiring replacement. Parts quoted through Williams Distributing still need to be ordered to complete all recommended maintenance items.
