For HVAC contractors
An engineer behind your install.
Owners and builders compare bids. An engineer's stamp on the design gives yours something a lower number can't.
What you get
We size every system from a real Manual J, and you get a stamped set with the schedule, duct layout, and notes the inspector reads, so you bid from the same numbers the inspector sees. Title 24 comes from the same office, so the energy report and your equipment agree.
We design. You install. Need only the load calc for a job you're designing yourself? That's a package too.
Jobs with the indoor air quality level add an ERV schedule, a filter schedule, a sensor points list, and a functional test script, so the ventilation, filter, and controls work is on paper before you bid.
Equipment that fits the calculated load
Every system is sized from a room-by-room Manual J, so the equipment you quote fits the calculated load.
A stamped set to bid from
Schedule, duct layout, and sheet notes, stamped by a licensed California mechanical engineer.
Title 24 that matches your equipment
The energy report and the mechanical sheets come from one office and use one set of numbers.
An engineer who answers
Plan check questions on our documents go straight to the engineer who did the work.
How it works
Three steps, little effort from you.
We calculate and design
We run the load calc, pick equipment to match, and design the ducts, ventilation, and Title 24 model.
You get a stamped set
A stamped set and a signed Title 24 report. Plan check questions go straight to the engineer.

A PDF of the architectural set is enough to start. We reply by email with questions, if any, and a fixed fee.
