What is Installed Per Design™?
This certification confirms that the HVAC system was installed exactly as designed — with no last-minute substitutions or undocumented changes. It ensures that the actual installed equipment, duct layout, airflow, and controls match the approved design documentation.
What’s Included?
- Field verification of equipment model numbers
- Duct system and control layout confirmation
- Measured supply and return airflow by zone or grille
- Photographic documentation of installation and controls
- Installer sign-off and third-party verification
Why It Matters
Too often, designs are ignored in the field — leading to oversized systems, incorrect ductwork, and poor comfort. Installed Per Design™ bridges the gap between the plan and the real-world installation.
Who Is It For?
- Builders and developers who want documentation and accountability
- Homeowners who want assurance their investment was installed right
- Green building programs requiring verified HVAC installations
- Design-build teams committed to quality assurance
