V. Comments/Observations

Observations

  • Filter Condition: Moderate dust and debris accumulation was observed on the filters, especially near intake vents. Replacement is scheduled for the following week.

  • Fan Blade Condition: Minor vibration detected in fan operation. Lubrication was completed, but further monitoring was advised to ensure no imbalance occurs.

  • Thermostat Accuracy: Thermostat showed a slight deviation from the target temperature of ±1.5°C; recalibration was performed to correct this.

Additional Comments

  • The technician noted that while the unit was operating within acceptable parameters, the blower motor showed signs of wear that may need evaluation or possible replacement in the next quarterly inspection.

  • Recommend adding a secondary inspection on the fan blade assembly due to a slight imbalance.
