Engineering design tools for residential HVAC workflows

EnerXCo provides connected residential design workflows for room-by-room heating and cooling loads and Manual D duct sizing while keeping each application independently accessible.

Current service

Manual D Residential Duct Sizing

Size residential supply and return duct systems using effective length, available static pressure, friction rate, room design loads, and runout/trunk airflow. Projects can remain independent or import room-by-room loads from an existing EnerXCo F280 project.

FAQ

Common questions

Does EnerXCo change the CSA F280 calculation method?

No. The current priority is preserving the verified calculation engine while improving the user interface, workflow, content, and report presentation.

Who is this tool intended for?

It is intended for residential HVAC designers, energy advisors, builders, and design professionals who need an organized CSA F280 workflow.

Can I create room-by-room load summaries?

Yes. The workflow is structured to support project-level and room-by-room load review.

Are future engineering services available now?

The CSA F280 residential load calculator and Manual D residential duct-sizing workflow are active. Cards that remain marked “Planned” are roadmap placeholders.
