FAQ
What do you need from me to start the HVAC design?
I typically need the architectural floor plan, project location, ceiling heights, window/door information, insulation details, and available equipment or design criteria. If anything is missing, I will identify the required information before proceeding.
Do you provide room-by-room Manual J calculations?
Yes. I can provide room-by-room heating and cooling loads, including design conditions, sensible/latent loads, airflow requirements, and the resulting load summary. Block-load calculations can also be provided when appropriate for the project scope.
Do you size the HVAC equipment from the calculated loads?
Yes. Manual J establishes the design load, while Manual S is used to evaluate equipment selection and capacity. I size equipment based on the calculated requirements rather than simply matching equipment to the home's square footage.
