What information is required to replace a 40 Ton rooftop HVAC unit?

What Information Is Required to Replace a 40 Ton Rooftop HVAC Unit?

Replacing a 40 Ton commercial rooftop HVAC unit requires more information than nominal cooling capacity alone.

For an accurate replacement evaluation, YUJU recommends collecting the following information from the existing equipment and building:

  • Existing manufacturer and model number
  • Nominal cooling capacity
  • Supply airflow
  • External static pressure
  • Voltage / Phase / Frequency
  • Downflow or horizontal configuration
  • Supply and return duct-opening dimensions
  • Existing roof curb dimensions
  • Fresh-air or economizer requirements
  • Heating configuration if required
  • Control-system requirements
  • Maximum allowable equipment dimensions
  • Project location
Recommended Replacement Workflow

Existing RTU → Capacity → Airflow & ESP → Curb & Duct Interface → Electrical → Refrigerant → Controls → Final Replacement Configuration

For replacement projects, installation photographs, the existing equipment nameplate and rooftop curb drawings can significantly improve preliminary equipment matching.

YUJU can support project-based evaluation for 20 Ton, 30 Ton, 40 Ton, 50 Ton and larger commercial rooftop HVAC replacement applications.
