Residential Load Calculation
Not every engagement is a drawing set. This one is the most common ask in residential HVAC: a permit-ready ACCA Manual J and Manual S report for a compact single-family home, delivered fast enough to keep an equipment change-out on schedule.
Sample sheets from this set
The engineering
Room-by-room Manual J loads for the whole house (≈25.5 kBtuh heating / ≈27.4 kBtuh cooling at design conditions), component construction analysis, and duct-system summary — then a Manual S equipment selection documenting that the chosen 1.5-ton system (18,000 Btuh cooling, 12,600 Btuh sensible, 14.5 SEER2, 600 CFM air handler) meets every ACCA sizing limit. The report includes the AHU-level breakdown and supply/return branch detail tables jurisdictions increasingly ask to see.
Why it’s in the portfolio
Florida jurisdictions reject rule-of-thumb sizing letters. A calculation package like this clears review as-submitted: the load math, the equipment data, and the compliance statement all cross-referenced in one document.
