Air Duct Cleaning FAQs, answered by experts

Several factors contribute to the persistent growth of mold in vents, with excess moisture being the most common culprit. Consistent mold formation in vents indicates an ongoing moisture problem within the HVAC system or its surroundings, likely caused by condensation on cool surfaces in areas with high humidity. Moisture accumulation can also result from leaks in ductwork, inadequate ventilation, or insufficient insulation, creating an environment favorable for mold growth. Regular inspections, addressing potential sources of moisture, maintaining proper ventilation, and routine HVAC maintenance can help prevent the recurrence of mold in vents. If the issue persists, seek professional assistance to identify and rectify the underlying problems.

Costs depend on grease buildup, labor, and whether ductwork requires deep cleaning.

You can add return vent filters to your HVAC system to help remove contaminants from the air. However, you should avoid adding return vent filters if your HVAC system already has a filter in its air handler. Filters can restrict airflow, which will make your HVAC system work harder.

Yes, rust in ductwork is bad if it’s left untreated. Mild rust can be removed before it causes any significant damage. However, if you ignore rust, it can affect the structural integrity of the ductwork, and you’ll eventually need to replace it entirely. In addition, rust-causing moisture in ducts can also cause mold growth.

If you notice increased energy bills, poor airflow, or frequent HVAC system issues, a professional assessment is advisable. Technicians can identify duct leaks or inefficiencies that require updating or maintenance.
