Every scope is a flat price set by conditioned floor area, for a single HVAC system — 5 business day turnaround, all 50 states. Need it sooner? 48-hour rush: +$99 on any tier. Over 5,000 sqft or 2 or more HVAC systems: custom quote.

A NOTE ON 2026 PRICING

The J + S + D bundle is priced by conditioned floor area rather than as one flat figure: $395 up to 2,000 sqft, $485 from 2,001 to 3,500, and $585 from 3,501 to 5,000. $485 is exactly what we charged before, and it still covers most homes — smaller projects simply pay less now, and only genuinely larger ones pay more. Above 5,000 sqft, or with two or more HVAC systems, we quote the job.

Earlier in 2026 the flat price moved from $350 to $485. That was Wrightsoft: on 1 April 2026 it consolidated Right-Suite into a single Residential subscription and retired the tier we had been licensed on, at a significantly higher annual cost. Right-Suite is the software every report here is produced in. Nothing about the deliverable changed — the same room-by-room Manual J, the same Manual S selection checked against AHRI data, the same Manual D duct sizing and layout, the same 5 business-day turnaround, and the same free revisions.

Block load vs room-by-room

SECTION 04
BLOCK LOAD

One load for the whole house

A single whole-building load — quick, and sometimes enough for equipment sizing alone. But it can’t tell you the airflow each room needs.

ROOM-BY-ROOM · REQUIRED FOR MANUAL D

A load for every room

Loads calculated room by room, so ducts can be sized to deliver the right airflow everywhere. Manual D duct design requires it — so every report we prepare is room-by-room.

Our guarantee & common questions

SECTION 06

COMPLIANCE STATEMENT

“We prepare your Manual J, S & D to ACCA standards for your project. If your permit office requests changes, we revise it free of charge until it is accepted.”
NAME — GET MANUAL JSD
DATE
What are Manual J, S and D?
Manual J is the ACCA heating & cooling load calculation; Manual S selects equipment to match those loads against manufacturer data; Manual D sizes and lays out the duct system to deliver the required airflow. Together they’re the standard HVAC design package.
Block load or room-by-room?
A block load gives one number for the whole house; room-by-room gives a load for each room. Manual D duct design requires room-by-room loads, so every report we prepare is room-by-room.
What do you need from me?
Your floor plan, the window and door schedule, building orientation, and insulation values (walls, ceiling, floor, windows). If some specs aren’t finalized, we can work from typical assemblies and adjust.
Is it accepted by my permit office?
Manual J/S/D prepared to ACCA standards is the widely accepted basis for HVAC permit review across all 50 states. If your office requests changes, we revise until it’s accepted.
How is the J+S+D price decided?
By conditioned floor area, as a flat price agreed before we start: $395 up to 2,000 sqft, $485 from 2,001 to 3,500, and $585 from 3,501 to 5,000. J only is $295 / $385 / $485 and J+S is $345 / $435 / $535 across the same size bands. Above 5,000 sqft, or where a home has two or more HVAC systems, we quote the job. $485 is unchanged from the single flat price we charged before, so most homes pay exactly what they always did — smaller ones now pay less.
Why did the price change in 2026?
Earlier in 2026 the flat price moved from $350 to $485. On 1 April 2026 Wrightsoft consolidated Right-Suite into a single Residential subscription and retired the tier we had been licensed on, at a significantly higher annual cost, and Right-Suite is the software every report here is produced in. Scope, the 5 business-day turnaround and free revisions until your permit office accepts the report are all unchanged.
Do you handle commercial buildings?
Yes — commercial cooling and heating loads are calculated in Carrier HAP using the ASHRAE heat balance method, for offices, retail, restaurants, warehouses, tenant fit-outs and multi-system buildings. Every commercial project is scoped and quoted individually: send your plans and you get a flat, all-in quote before any work begins. No hourly billing. Turnaround is 1–2 weeks.
Can you do it faster?
Yes. Add the 48-hour rush on the order form and your draft arrives within 48 hours of complete plans, for +$99 on any tier.
I don’t have insulation values or a window schedule.
We use code-minimum values for your climate zone and list every assumption in the report. Send better data at any time and we update it.
Can you work from a hand sketch?
Yes, if it is dimensioned and shows window sizes and orientation. Photos on their own are not enough.
ADUs, additions and remodels?
Yes — same tiers, priced by the conditioned area of the new or affected space.
Canada, Title 24 or Manual T?
Available on request: Canadian residential loads to CSA F280, California Title 24 energy compliance and Manual T register and grille selection. Each is quoted.
Is the ventilation calculation included?
Yes. The whole-house mechanical ventilation calculation is included in the Manual J package at no extra charge.
What if the equipment model changes after the report?
The first equipment change is free. Each later change is $49.
We build the same plan in several orientations.
Each orientation needs its own Manual J report, so each is a separate order. Builders with repeat plans can ask us about builder pricing.
When do I pay?
When you order, you enter your card on Stripe’s secure checkout and the price is put on hold — nothing is charged yet. We charge the card when your draft is delivered. Card holds last 7 days, so if a draft ever runs past day 6 we charge it then. If we can’t deliver, the hold is released and you pay nothing. Commercial and other quoted work is different: nothing is charged until you accept the quote.
How are my plans handled?
Your files are used only to prepare your report. We don’t publish or share them.
