Cleaning the air handling unit

The air handling unit is the central point of the installation. What happens here determines the air quality in all the rooms behind it.

We clean the inside of the unit: the fan housing, the chambers, the internally accessible surfaces and the connections. The filter section is assessed and, depending on the agreement, cleaned or replaced.

The unit is often large and only accessible through a roof hatch, a technical floor or an inspection door. That access determines what is possible.

Installations this work applies to

  • Air handling units in technical rooms and on rooftops
  • Filter chambers with pocket, panel or fine filters
  • Fan sections with axial or radial fans
  • Bypass and heat exchanger sections in the same unit

What we do within this service

  • Cleaning of the internal chambers and the fan housing
  • Cleaning of the filter chambers and the filter frames
  • Assessment of the filter section for loading and fit
  • Cleaning of the access hatches and the seals

Conditions, prerequisites and technical limits

  • The heat exchanger and the controls are not dismantled or cleaned.
  • For a unit that is only accessible through a roof hatch, the height and the weather dependence are part of the planning.
  • Filter replacement is a separate supply; type and size are agreed in advance.
