FAQ
Can you prepare HVAC calculations and drawings for city permit approval?
Yes. I prepare permit-ready HVAC calculations, duct layouts, equipment schedules, and mechanical drawings based on applicable codes and local submission requirements. My goal is to provide clear, accurate documentation that supports a smoother permit review process.
Can you provide a PE-stamped HVAC plan if my city requires one?
PE review and sealing may be available for eligible projects in jurisdictions where the responsible engineer holds the required active license.
Can you calculate CFM airflow, duct sizes, and static pressure?
Yes. I can calculate room-by-room airflow requirements, supply and return CFM, duct sizing, friction losses, and external static pressure. These calculations help establish an appropriate air distribution design for your HVAC system.
Can you help correct HVAC drawings rejected by the building department?
Yes. If your city has issued HVAC or mechanical plan review comments, I can assess the corrections, update calculations and drawings within the agreed scope, and prepare revised documentation for resubmission. Share the comments and existing plans for review.
How do you ensure your HVAC calculations are accurate and meet local building codes?
I carefully review your building plans, insulation, windows, and local code requirements to prepare accurate, project-specific HVAC calculations. My approach follows applicable ACCA and ASHRAE standards, with attention to proper system sizing, reliable airflow, and permit requirements.
