Quick Comparison
| Option | Best For | What to Verify | Common Risk |
|---|---|---|---|
| DIY check | Routine monitoring | Cap movement, visible lint, basic dry-time trend | Missing hidden restrictions |
| Targeted repair | One known fault | Secure joints, stable airflow, repeatable results | Treating symptom only |
| Professional service | Persistent or complex issue | Measured airflow and written scope | No baseline for comparison |
Pick the right next step before making changes.
