Performance Testing
At Junior the Rater LLC, we provide professional performance testing for both residential and nonresidential projects to ensure HVAC and building systems operate efficiently and meet Title 24 energy standards. Our tests verify airflow, pressure, insulation quality, and envelope tightness — helping contractors and homeowners achieve optimal comfort and guaranteed compliance.
Residential Performance Testing
We perform complete home performance testing to measure energy efficiency, comfort, and code compliance. Each test helps identify issues before final inspection so homes pass the first time and run more efficiently.
Includes:
-
Blower Door Testing (Envelope Leakage) – Measures airtightness and helps locate leaks for energy savings.
​
-
Duct Leakage & Airflow Testing – Ensures ducts are sealed and air is properly distributed.
​
-
Static Pressure Testing – Confirms proper fan operation and balanced air distribution.
​
-
QII (Quality Insulation Installation) – Verifies insulation is properly installed for full performance credit.
​
-
Air Balance & CFM Reports – Documents airflow results for city and Title 24 compliance.
Nonresidential Performance Testing
We offer advanced testing for commercial properties, restaurants, and mixed-use buildings to ensure mechanical systems meet Title 24 requirements and maintain proper ventilation performance.
Includes:
​
-
Air Balance & CFM Verification – Confirms exhaust and supply systems operate within design specs.
​
-
Static Pressure Testing – Validates duct sizing and fan performance.
​
-
Commercial Exhaust System Testing – Ensures proper airflow for kitchens and workspaces.
​
-
Ventilation Performance Testing – Verifies air changes per hour for code compliance.
​
