When did your air returns last get cleaned?
What's in your returns is in your air.
Air returns accumulate dust and debris that your HVAC system circulates through the building every time it runs. DFX physically cleans and dusts the air returns — removing that source before the system re-contaminates itself with a fresh filter.

- Visible dust buildup on or around air return vents
- Filters clogging faster than expected — often a sign of dirty returns upstream
- Musty or stale odors that worsen when the HVAC runs
- Staff or occupants reporting increased dust or allergy-type symptoms
- No documented cleaning of returns in recent service history
- Post-renovation or post-construction environments where debris has entered the system
How we treat air return cleaning
A targeted approach for lasting results.
Inspect air returns
We inspect each air return in the facility to assess the level of buildup — dust, debris, and any other accumulation in the return housing and surrounding area.
Physical clean and dust
Returns are physically cleaned and dusted. This removes accumulated buildup from inside the return housing so it isn't circulated back through the system once the HVAC runs again.
Ready for replace and treat
With clean returns, the next steps — replacing filters with hospital-grade treated replacements and applying disinfectant through the system — work from a clean starting point rather than re-contaminating through dirty returns.
