I will draft hvac duct routing airflow and ventilation permit plans

Need an HVAC drawing that installers can understand and a plan reviewer can follow?

I will prepare coordinated duct-routing, airflow, ventilation and mechanical equipment plans for residential or light-commercial projects.

Drawings can show supply and return duct routes, duct dimensions, room airflow values, diffusers, grilles, registers, equipment locations, thermostats, exhaust fans, outdoor-air provisions, condensate routing and mechanical notes. Where available, I can coordinate the layout with Manual J room loads, Manual D sizing, architectural plans, ceiling conditions and structural framing.

This service is suitable for new homes, ADUs, additions, remodels, basement conversions, equipment replacements and small commercial tenant improvements.

Final deliverables can be provided in PDF and, when included, an editable CAD format.

Please send the floor plans, equipment information and calculation reports before ordering. Manual J/S/D calculations, structural design, electrical plans, professional stamping and guaranteed permit approval are not included unless added to the agreed
