Responded to callback for Suite #105 (Great Clips) regarding non-operational air conditioning unit following recent maintenance visit. Upon arrival, inspected Goodman model 7E036H10A2A1ABA1A2 rooftop unit (208/230V-3-60, R410A refrigerant). Removed access panel and performed diagnostic evaluation of electrical and mechanical components including control board, blower motor, capacitors, wiring connections, and refrigerant lines. Identified issue, completed necessary repairs to restore cooling operation, and verified proper system function before departure.

Completed scheduled commercial heating maintenance visit on rooftop HVAC unit. Performed comprehensive system diagnostics using Fieldpiece digital measuring instruments, recording operational readings of 13.8 on diagnostic display. Accessed interior components through service panels to inspect heat exchanger coils, electrical wiring connections, and mounting hardware. All components found to be in functional condition with normal outdoor weathering present. System operating within acceptable parameters.

Completed full HVAC system retrofit including furnace and air conditioning equipment. Installed new condensing unit and evaporator coil, replaced existing furnace with high-efficiency model, and upgraded all refrigerant lines to accommodate R-410A refrigerant. Performed complete system evacuation achieving deep vacuum of 229 microns, well below the 500-micron industry standard for proper moisture removal. Conducted precision leak test using digital manifold gauges, confirming system integrity with zero pressure drop over five-minute test period at 410.4 psig. All connections were brazed to manufacturer specifications, electrical wiring was verified for proper voltage and amperage, and condensate drainage was tested for proper flow. System was charged to factory specifications, airflow was balanced across all zones, and final operational testing confirmed all safety controls and thermostatic functions operating correctly.

Successfully installed a Hoiswell whole-home dehumidifier in the basement mechanical room to improve indoor air quality and control humidity levels. Unit was positioned on the concrete floor near existing HVAC equipment, connected to drainage system via PVC piping, and tested for proper operation with digital display confirming active humidity monitoring at 47% relative humidity.

# HVAC Service Call - No Cooling Issue Responded to service call for 22-year-old air conditioning unit with no cooling complaint. Upon arrival, performed system diagnostic to identify cause of failure. Inspected outdoor condensing unit and found failed dual run capacitor preventing compressor and condenser fan motor operation. Capacitor showed visible signs of deterioration and tested out of specification range using multimeter. This is a common failure point on units of this age due to normal wear and extended service life. Removed defective capacitor from mounting bracket and disconnected all electrical connections including common, compressor, fan, and HERM terminals. Installed new dual run capacitor with proper microfarad rating matching manufacturer specifications for the equipment. Reconnected all electrical wiring to appropriate terminals ensuring proper color coding and secure connections. Restored power to unit and verified compressor and condenser fan motor startup. Monit

Responded to callback regarding failed silicone sealant around undermount kitchen sink. Upon inspection, discovered all previously applied silicone had deteriorated or separated from the granite countertop and sink junction. Documented existing conditions showing undermount stainless steel basin with granite countertop and backsplash. Assessed adhesion failure and prepared area for re-application of appropriate silicone sealant to restore proper water barrier and prevent moisture intrusion beneath countertop.

Completed comprehensive estimate for full HVAC system replacement in residential basement installation. Assessed existing furnace and air conditioning equipment configuration, evaluated current ductwork infrastructure including main trunk line, and documented mechanical room layout with water heater proximity. Provided detailed replacement specifications for new high-efficiency heating and cooling system retrofit to upgrade aging equipment while maintaining existing duct distribution network.

Completed HVAC new construction finish work including installation of thermostats throughout the home, with second floor thermostat relocated to designated tape area for proper placement. Finished ducting for range hood exhaust system and completed electrical wiring for make-up air unit to ensure proper ventilation and code compliance. Performed system start-up procedures on all HVAC equipment, verified proper operation of heating and cooling systems, and conducted preventive maintenance inspection to ensure optimal performance.

Completed installation of two outdoor air conditioning units for new construction project. Installed supply and return registers throughout the residence, with careful masking and floor protection to preserve newly finished surfaces during final HVAC trim-out phase. All register installations secured and system ready for startup.

Completed scheduled commercial cooling system maintenance inspection. Verified supply air temperature at 45.5°F using calibrated digital thermometer, confirming proper cooling performance. Inspected damper actuator assembly, motor mechanism, and associated control wiring for proper operation and secure mounting.

Performed routine heating maintenance on residential furnace. Conducted combustion analysis with Bacharach analyzer confirming system is operating at 91.7% efficiency with CO levels at 3ppm and stack temperature at 109°F, indicating proper combustion and safe operation within manufacturer specifications.

Completed rough-in phase of new construction HVAC installation, including placement of bathroom exhaust fan in ceiling and installation of floor register. Confirmed proper ventilation setup with appropriate ceiling cutouts and verified register positioning according to blueprints.
