Conducted site assessment of basement mechanical room to evaluate ductwork modifications for improved clearance and safety. Evaluated existing galvanized ductwork configuration and HVAC equipment placement to determine feasibility of reducing duct dimensions from 8 inches to 4 inches on one side to eliminate head hazard concerns. Assessed options for repositioning ductwork against wall or relocating to bedroom area to provide adequate clearance above sleeping space. Evaluated potential relocation of furnace unit closer to side room to improve space utilization and reduce obstruction in main basement area. Documented existing installation including water heater, air handling unit, copper piping, and ductwork connections. Provided recommendations for ductwork reconfiguration while ensuring compliance with applicable building codes and maintaining proper airflow requirements for system performance.

# Service Report: Commercial Circulator Pump Replacement Responded to commercial facility for circulator pump replacement on heating system loop #5. Coordinated with on-site personnel for access and equipment stabilization during installation. Successfully removed failed pump assembly and installed replacement circulator unit on the hydronic heating system. Verified proper mounting, connection integrity of grooved pipe couplings, and system pressurization. Restored heating loop to full operational status and confirmed circulation performance met system specifications.

Completed spring Clean & Check on American Standard HVAC system per Comfort Plan agreement. Inspected and serviced outdoor condensing unit (#9231) and indoor furnace components. System is operating within manufacturer specifications with no issues identified. All connections are secure with proper airflow maintained.

Successfully completed installation of a new Lennox Two-Stage, Variable 66k forced air furnace, replacing the existing unit. Connected the new furnace to existing ductwork with necessary sheet metal transitions, gas line, electrical circuit, and exhaust system. Performed startup testing and safety inspection, confirming proper operation of all components including the condensate pump and drainage system.

Diagnosed non-ignition issue on furnace where customer reported thermostat set to 70°F with actual temperature reading 58°F. Inspection of the unit revealed electrical component malfunction requiring replacement of control board and associated wiring. Complete system evaluation determined aging unit would benefit from full replacement rather than continued repairs to ensure reliable heating performance and proper ventilation through existing PVC ductwork.

Responded to no-heat call for furnace not igniting with indoor temperature at 58°F despite thermostat set to 70°F. Inspected unit and discovered dirty air filter causing airflow restriction. Replaced filter and verified proper ignition sequence, restoring normal heating operation.

Responded to service request for Pump #5 which was reported to be overheating without apparent operation. Upon inspection, found the pump's internal components showing signs of wear with excessive heat buildup. Documented the valve assembly and piping configuration with photos for upcoming maintenance. Confirmed valve position was open as reported by remote monitoring. Issue has been noted for comprehensive evaluation during scheduled Spring maintenance service.

Responded to service call for 20+ year old boiler system where half the house lost heat in one of two zones. Diagnostic inspection revealed a faulty circulator pump. Pressure gauge readings were verified and the system was tested after repair to confirm proper heat distribution to all zones. Recommended maintenance schedule discussed with customer due to age of system.

Successfully installed a new 50-gallon water heater in basement, replacing the existing unit. Connected to existing exhaust chimney, gas, electric, and water piping systems. Performed complete startup, testing, and safety inspection to ensure proper operation, with installation covered by 6-year warranty on functional parts and tank plus 1-year labor warranty.

Performed annual boiler clean and check service on residential heating system. Inspected copper piping network, valves, zone control devices, and green boiler unit with exhaust venting. System shows normal aging but remains in functional operating condition with no immediate issues requiring repair.

Responded to customer complaint regarding odor from HVAC equipment. Inspected system and verified thermostat operation (Venstar unit showing 78°F reading). No issues identified with equipment; confirmed proper functionality with no unusual odors present during testing.

Returned to service an Indirect NTI Water Heater exhibiting a slow drip from the bottom with slight overflow into the catch pan.
