FOR THE TRADECONTRACTOR RESOURCES · LOAD CALCULATIONS
Manual J, D & S —
done right, on paper.
Guessing at equipment size is how callbacks happen. We perform proper ACCA Manual J load calculations, Manual D duct designs, and Manual S equipment selections for projects across Hampton Roads — and hand you the paperwork to prove it.
WHAT YOU GET
The full design package,
not just a tonnage.
A proper system design answers three questions in order. We deliver all three, documented.
- 01
Manual J — the load
Room-by-room heating and cooling load calculation using ACCA-approved methods: envelope, windows, orientation, infiltration, and internal gains for your specific building.
- 02
Manual S — the equipment
Equipment selection matched to the calculated load — capacity, airflow, and sensible/latent split verified against manufacturer performance data, not the box label.
- 03
Manual D — the ducts
Duct sizing and layout designed around the required room-by-room airflow, available static pressure, and fittings — so the air actually reaches the rooms that need it.
- 04
The paperwork
Everything compiled into a documentation package you can hand to the permit office, the builder, or your customer — load summary, room-by-room detail, duct schedule, and equipment selection.
WHO THIS IS FOR
Builders, remodelers,
contractors, homeowners.
If your project is in Hampton Roads and the paperwork matters, we can help.
Permit submittals
New construction, additions, and changeouts where the building department wants to see the load calculation behind the equipment size.
Other contractors
No time to run the numbers in-house, or no Manual J software on the shelf? Send us the plans or book a walkthrough and we will run the design for you.
Homeowners replacing equipment
Want to know your home actually needs what is being proposed? We measure the house, run the numbers, and give you the paperwork to compare bids against.
