Manual J - Load Calculation

We use advanced ACCA-approved software to calculate the exact heating and cooling loads for your project. Every room is analyzed for insulation, windows, infiltration, and orientation to ensure your HVAC system performs at peak efficiency.

Deliverables

Full room-by-room heating & cooling load report
Total system capacity summary
Building envelope and design conditions summary

Manual S - Equipment Selection

Using the Manual J results, we select properly matched HVAC equipment that meets system requirements without oversizing. This ensures comfort, lower energy bills, and extended equipment life.

Deliverables

Equipment sizing verification
Cooling and heating performance data
SEER/HSPF efficiency validation for compliance

Manual D - Duct Design

We provide detailed duct layouts and sizing based on pressure drop, friction rate, and airflow balance. Each design is optimized for quiet operation, comfort, and efficiency. Duct design/layout based on your specific needs.

Deliverables

Duct layout schematic (PDF)
Supply and return airflow balance report
Friction loss and static pressure calculations
