Heating and Cooling Taylor

Returned to site with replacement fuses for rooftop unit. Restored power to RTU and performed complete combustion analysis and thorough visual inspection of heat exchanger. During inspection, observed significant frost accumulation on refrigerant lines indicating potential system issues. Documented extensive ice buildup on insulated piping with visible rust staining on pipe insulation. Verified proper operation of heating components and confirmed heat exchanger passed visual inspection with no cracks or deterioration detected. Combustion analysis results within acceptable parameters. Unit left operational with power restored. Photographed refrigerant line conditions showing heavy frost formation on multiple parallel pipes, which may require future attention for possible refrigerant flow restrictions or insulation concerns.

Responded to service call for 2-year-old furnace in basement experiencing intermittent shutdowns and displaying 5-blink error code. Upon arrival, furnace was operational. Performed comprehensive diagnostic testing using digital multimeter to check electrical components, including voltage readings at control board, safety circuits, and flame sensor connections. Tested pressure switches and verified proper operation of ignition system. Measured system pressures at 350 PSI to confirm adequate gas supply and proper combustion. Inspected all wire connections at control board and contactor, verifying secure terminations of red, black, white, and green conductors. Checked condensate drainage system and P-trap configuration for blockages that could trigger safety shutoff. The 5-blink error code typically indicates pressure switch or venting issues; verified all PVC vent pipes were clear and properly configured. System tested through multiple heating cycles with no faults detected. All electric

Responded to no-heat call for furnace displaying fault code. Inspected internal components including circuit board with illuminated red indicator light, heat exchanger, and wiring connections. Diagnosed and repaired faulty control board causing system failure, restoring proper heating operation.

Performed diagnostic assessment on furnace that was not auto-igniting, blowing cold air, and experiencing burner ignition failure. Inspected and tested the blower motor assembly, finding it operational but detected issues with the ignition control module. Replaced faulty ignition module, cleaned flame sensor, and verified proper burner ignition sequence. System now functioning correctly with appropriate heat output and automatic cycling.

Responded to emergency no heat call for aging residential heating system with significant corrosion at circulation pump connections. Diagnosed failed aquastat relay and deteriorated dielectric union. Replaced aquastat relay, dielectric union, and installed new nipple tray to restore system operation and prevent future galvanic corrosion issues.

Completed Gold Furnace Inspection on 7-year-old forced air system located in basement. Inspected air filter/evaporator coil assembly, noting some discoloration indicating maintenance may be needed soon. Also observed Bradford White water heater with proper copper piping connections and ventilation components in good working condition.

Performed electrical inspection to diagnose flickering lights and circuit overload issues. Inspected attic wiring and found evidence of outdated electrical system with improper wiring connections. Recommended panel upgrade and partial rewiring to address safety concerns and prevent further breaker trips.

Completed tune-up service on an aging blue furnace unit located in garage. Performed comprehensive inspection of heating system including thermostat, humidifier, and hot water tank components. System shows normal wear with some surface corrosion but remains operational; documented condition with photos for service records.

Performed furnace inspection on unit of unknown age located in laundry room, including examination of the gas valve system. Inspected and documented condition of internal components showing signs of age and corrosion. Comprehensive tune-up included checks of humidifier, thermostat, and hot water tank.
