I am enlarging several window openings in a wood-framed exterior wall and plan to install a new HVAC unit in the attic directly above. Before any demolition or equipment placement begins, I need formal structural calculations that confirm the modified wall—and the supporting roof and attic framing—will safely carry all new loads. Your analysis should account for: • The change in load paths created by the larger window headers • The additional point and distributed loads introduced by the HVAC unit (equipment weight and vibration) • Any related shear or lateral requirements for a wood exterior wall in my locality Please provide sealed or ready-for-permit calculation sheets, clearly showing assumptions, governing codes, load combinations, and member sizing. A concise summary of recommended framing adjustments (header sizes, king/trimmer studs, any required posts or beams, and attic joist reinforcement) will help my builder price the work quickly. I can supply existing drawings, dimensions, photos, and the HVAC equipment specs as soon as we start. Let me know if you need anything else to complete the analysis.
