I need a complete set of HVAC specifications and drawings for my two-storey home and I’m on a tight timeline. The system will be Central Air Conditioning with both heating and cooling capability. All rough-ins start on the 1st floor and must feed both levels: three bedrooms on the main level, two bedrooms upstairs. Deliverables I’m expecting: • Load calculations and equipment sizing • Duct layout with correct sizing and balancing notes • Locations for all rough boxes, returns and supplies • Equipment schedule based on the specific brands and models I’ll provide once we begin • A clear plan set (PDF plus CAD or Revit file) ready for my contractor and local permit submission Please follow current residential codes and typical Manual J/S/D procedures. Speed is key, so let me know how quickly you can turn the first draft.
