FAQ
What is an HVAC Manual J load calculation?
Manual J estimates a home's heating and cooling loads using building characteristics, climate, windows, insulation, and other relevant inputs. It helps determine the required system capacity.
What is the difference between Manual J, Manual D, and Manual S?
Manual J calculates heating and cooling loads, Manual D sizes the duct system, and Manual S helps select suitable HVAC equipment based on the calculated loads.
Can you prepare reports for new construction or permits?
Yes, depending on the selected package and project requirements. Please share your local jurisdiction's checklist before ordering. Final acceptance depends on the reviewing authority.
How much does a complete Manual J, D, and S design cost?
The Premium package starts for the defined scope. Larger homes, additional systems, complex duct layouts, and special documentation may require a custom quote.
Will you keep me updated during the project?
Yes. I will communicate at key stages, clarify missing information, and inform you of any scope or timeline concerns before they affect delivery.
Can I request revisions if my contractor needs changes?
Yes. Revisions within your package's stated scope are included. Changes to floor plans, building specifications, or the original project scope may require an additional fee.
