What to record before calling
- Record whether noise occurs at startup or continuously.
- Identify recent service or weather-related changes.
- Report reduced airflow and shutdowns with the noise.
What the service assessment can cover
Motors, bearings, belts, mounting, and other rotating components may need inspection. Keep staff away from moving equipment and use authorized roof access.
Should a belt be tightened until the noise stops?
Belt condition and tension need to match the equipment requirements. Improvised adjustments can leave the underlying issue unresolved or damage components.
