Signs of Excess Dust
The dust that thickly accumulates on the walls of ducts actually presents no risk to your indoor air quality or HVAC system efficiency. However, it’s crucial to recognize when a cleaning is necessary.
- When particulates are visibly emitted from your system, it could signify an excess of dust and dirt in your ducts.
- If you’re having unusual humidity issues, such as air that feels “sticky” or abnormally dry, your ducts may not be allowing airflow as it should. Given the issues that improper humidity levels present, balanced humidity is what you want all year long.
- If your ducts are inexplicably less powerful, or if it produces weaker “stale” air, a large blockage could be limiting your airflow.
- When you’re experiencing an unexplained lack of efficiency despite well-maintained equipment and regular energy audits, your clogged ducts might be culpable (and can result in up to 40% improved efficiency once cleaned.)
