THE EQUIPMENT GUIDE / Commercial & building systems

Air handling units

Air treatment assembled around a building's needs.

An air handling unit moves and conditions air using a configured set of components. Fans, filters, coils and outdoor-air arrangements must work as a system.

PLANNING / SELECTION / HANDOVER

Before choosing the equipment

Bring airflow requirements, space constraints and indoor environmental goals. Ask how component access and future replacement routes are provided, especially in crowded mechanical rooms.

What belongs in the quote

The quote should include the component schedule, controls interfaces and balancing. Request filter specifications and a commissioning record for the installed configuration.

Think about the surrounding system

Bring operating hours, occupancy patterns, tenant constraints and existing equipment schedules to the first discussion. Agree who owns design, electrical work, structural review, roof penetrations, controls and commissioning. Plan shutdowns around the building rather than discovering access restrictions when replacement equipment arrives.

Three questions for your contractor

  1. Which components are included in the unit?
  2. How will filters and coils be accessed?
  3. What airflow verification is specified?

Prepare a useful first conversation

Bring the site location, building use, equipment model details and photographs of accessible equipment. Describe the problem or planned change and any access or shutdown constraints. Ask the contractor to identify design assumptions, excluded work, required approvals and who will commission the finished system.

This is a project-planning guide. Final equipment selection and installation details need a qualified contractor or designer familiar with the site.
