    I need my existing permit-set drawings refreshed to include structural detail for an HVAC screen on the roof. The base files are already modeled; what is missing are clear material specifications and mounting details that satisfy local building codes so the plans can move through building-department review without delays. You will take the original DWG files, add the required sheet(s) showing the screen’s framing, connection points, and call-outs, then generate a clean, print-ready PDF set. I work in AutoCAD, so please keep everything in that environment (no format shifts). Deliverables will be: • Updated DWG files with the new HVAC screen notes, sections, and details • Matching PDF sheet(s) ready for immediate submission Please leave the existing title block, revision...

    Hello, I am writing to inquire if your firm provides forensic mechanical engineering evaluations and written reports for residential HVAC systems. I am seeking a licensed Professional Engineer (P.E.) to conduct an independent technical evaluation of an improperly sized HVAC installation at my residence in Valrico, Florida. Background Summary: Three years ago, an HVAC contractor recommended and installed a 5-ton A/C unit to replace an aging 4-ton system. However, the contractor installed the 5-ton unit onto existing ductwork designed strictly for a 4-ton capacity without making necessary duct modifications or verifying airflow limits. This has led to chronic operational issues and high static pressure. Scope of Work Requested: I am looking to retain a P.E. to perform an on-site assessment a...

    My 1750 single-family house is currently gutted down to the studs, giving us a clean slate to run brand-new flexible ducting throughout the entire structure. The existing oil-fired, forced-air furnace and tank sit in the basement and will remain as the air-handling core, so every new supply and return line must tie neatly into that equipment. Scope • Design and install a complete flexible-duct distribution system that reaches every room. • Size trunks, branches, supply registers, and returns so the furnace can deliver balanced airflow without excessive static pressure. • Route, hang, seal, and insulate all flex runs to meet current code and eliminate leakage. • Leave clear access for future service and any eventual central-air add-on. Site Conditions ...

    I maintain an HVAC blog read primarily by working technicians, installers, and service managers, and I want each post to give them immediately usable maintenance tips without slipping into dry jargon. Your task is to research and write original, technically sound articles that show a clear grasp of preventive upkeep—think step-by-step inspection procedures, troubleshooting checklists, and component-level insights that help professionals keep systems running efficiently. The voice should hit a balanced, informative middle ground: enough depth and data to satisfy an experienced tech, yet still structured and engaging so the material is quick to absorb on a coffee break. References to current ASHRAE guidelines, manufacturer service bulletins, or recent code updates are welcome whenever...

    I’m working on an ongoing residential project in the City of West Covina and need our current Title 24 California Energy Report (CF1R) brought up to the 2026 standards. The existing CF1R package is complete through the previous code cycle, and I already have all the underlying energy-efficiency measure data on hand. Your task is to revise the energy efficiency measures and the compliance documentation so the report aligns with the 2026 Title 24 requirements, including any newly adopted prescriptive or performance criteria. All utility data sections are already in order, so the focus will be on recalculating, re-narrating, and re-formatting the portions that reference measures such as envelope performance, HVAC, DHW, and lighting, then updating the corresponding compliance forms.
