Manual J + S + D · $100 per house

Our price

$100 per dwelling unit for Manual J, Manual S and Manual D together, as one matched package. The price is confirmed before we start, with no subscription and no minimum.

What drives prices elsewhere

Load calculation services price by house size, number of zones, rush delivery and whether engineering stamps are needed. Doing it in-house costs a software license, training and the hours to enter every room and window.

When a flat price works

For single-family homes, townhomes, additions and replacements with normal plans, the work per house is predictable. That is what the $100 price covers. Unusual projects such as very large custom homes or multiple systems are quoted before we start.
