✅ Ready to jump in and get this done the right way—clean, fast, and reliable. ✅ I understand that you need an accurate HVAC Manual J load calculation for proper system sizing, permitting, and installation planning. This isn't a project where rule-of-thumb estimates are acceptable—the calculations must be based on actual building characteristics, climate data, insulation values, window specifications, infiltration rates, and occupancy factors to ensure reliable results and code compliance. ACCA Manual J is the industry standard for this type of work. With experience in HVAC design, mechanical engineering, and building load analysis, I can deliver a complete, well-documented calculation package with clear heating and cooling load results, room-by-room breakdowns, equipment sizing recommendations, and supporting documentation suitable for permit review if required. I value accuracy, communication, and timely delivery. If you can share the plans and project details, I can review them immediately and confirm the required turnaround time. I look forward to helping you complete this project successfully.

With my skills in AutoCAD, CAD/CAM, HVAC, and Mechanical Engineering, I can run the necessary analysis, accurately interpret your existing Manual J data, and provide you the essential Manual S calculation with the AHRI certificate for your project. Additionally, my architectural background guarantees that I'll consider not just the technical aspects but also more holistic factors like aesthetics and code compliance. Finally, as a seasoned professional in Seminole County FL 32750 area, I'm familiar with local guidelines and regulations while being connected within the industry. This means my work not only meets but often exceeds the regional demands.

Hi there, I’ve completed very similar HVAC sizing projects, including Manual S equipment selection using provided Manual J reports, and I can help prepare the Manual S calculation with AHRI certificate for your Mitsubishi ductless multi-unit system in the Seminole County FL 32750 ADU. I have some thoughts on matching the Mitsubishi units accurately to the provided loads and permit expectations that I'd like to run past you. Best regards, Robert
