Capacity alone does not determine the right central plant. Climate, operating profile, water strategy, acoustics and available space all materially change the answer.

An air handling unit selection is only as reliable as the brief behind it. Airflow, design conditions, filtration, heat recovery, the space available and the control strategy all shape the unit.

External static pressure connects a fan's rating to the ductwork it serves. Misjudge it and a correctly sized unit can deliver the wrong airflow, make more noise or use more energy than intended.

Both approaches can serve a commercial building well. The better choice depends on building size, how the building is let and occupied, plant and riser space, refrigerant limits and how the system will be maintained and eventually replaced.
NOTE 05
Replacement Guides · 4 MIN READ
Most replacement projects take place in buildings that cannot simply close. Disruption is avoided by understanding what the existing system really does, deciding what must keep running and phasing the work around it.

Equipment selected from nominal ratings can fall short in the Gulf. High design ambient, coastal humidity, salt-laden air and dust all change how equipment performs and how long it lasts.
