HVAC Design for Ontario Contractors: You Install It. We Design It, Stamp It, and Answer the Examiner.

You know how to install a system. What eats your week is the paperwork: the F280, the duct layout, the ventilation summary, Schedule 1, and a BCIN that nobody in your shop has.

We do that part for you. You keep the customer, the install and the margin. We never sell equipment, so we are never your competition.

We never sell or install equipment. We are never your competition.

Why Contractors Use Us

No BCIN in the Shop

The designer who signs a permit design needs the right qualification. We have it, so you do not need to.

Load Calcs Eat Time

A proper F280 takes hours your techs should spend installing. We turn it around fast.

Customers Will Not Pay for It

A stamped design up front saves you the callback and the argument about sizing later.

Inspections Go Smoother

A complete design gives the inspector something clear to check your install against.

How It Works

1. Send the Job

Drawings or a sketch, the address and what you plan to install.

2. We Run the Numbers

CSA F280 at the right design temperature, duct or radiant layout, and the ventilation summary (RMVDS).

3. Signed and Sent to You

BCIN-stamped, Schedule 1 done, delivered to you.

4. We Answer the Examiner

If comments come back on our design, we handle them.

The clean split

The designer signs and takes responsibility for the design. The contractor installs it. That is what the building department wants to see, and it keeps the sizing argument off your back.

Contractor Questions
Can you do the design for jobs I am installing?

Yes. Send the drawings or a sketch and the job details. We do the CSA F280, the design and the ventilation summary (RMVDS), signed by a BCIN designer, and send it to you.

Who signs the design?

Our BCIN-registered designer signs it and takes responsibility for it on Schedule 1. You install it. That is the clean split the building department wants.

Will you send the report to my customer?

We send it to whoever orders it. If you order it, it comes to you, and you decide what goes to the homeowner.

Do you sell or install equipment?

No. We will never compete with you for the install. That is the whole point.

How fast is the turnaround?

Most reports within 48 hours of payment once we have what we need. Tell us if a job is urgent.

Do you have contractor pricing?

If you send us regular work, ask. We would rather have a steady partner than a one-off job.
