You have a heat loss report and something feels off. The number looks huge for the house. Two contractors quote equipment a full size apart. Or the building department just sent your HVAC drawings back.
A second set of eyes is cheap compared to buying the wrong equipment. Here is what we check, what we usually find, and what you get.
Is it the right value for your town? A few degrees off changes everything. See design temperature.
Do the window areas and U-values match the drawings and what is actually being installed?
Are the wall, ceiling, basement and slab values what is really being built?
Is it a reasonable assumption, or a measured number? Guesses can swing the load a lot.
Is the heat needed to warm fresh air from the HRV included properly?
Does the equipment cover the load? For heat pumps, at the design temperature, not on the nameplate.
One says 3 tons, one says 5. A review shows which is closer to the truth.
The report says your small house needs a huge furnace, or a big house needs very little.
The examiner sent comments. We fix the package and it goes back signed. See permit rejected.
A heat pump or geothermal system is a big cheque. Check the number first.
Does the report hold up, yes or no, and why.
If something is wrong, exactly what, and how much it changes the result.
If you need it, a corrected CSA F280 and design, BCIN-stamped and ready for the permit.
We do not sell or install equipment. Our only interest is the right number.
The report, the drawings it was based on, and anything that changed since: windows, insulation, equipment. If your permit came back, include the examiner’s comments. If there is a ventilation summary (RMVDS) and energy form, send those too, because they all have to agree. See the RMVDS.

The wrong design temperature for the town, window areas that do not match the drawings, insulation values that are better or worse than what is being built, guessed air leakage, and heat pumps picked from their nameplate rating instead of their output at the design temperature.
Yes. Send the comments, the original package and the drawings. We correct it and it goes back signed. See HVAC permit rejected.
That is one of the best uses of a review or a fresh heat loss. We sell no equipment, so we have no reason to favour either quote.
Yes. If the numbers hold up, we say so. Paying for a review that confirms a good report is still money well spent.
It depends on the size of the house and what you need: a quick check, or a corrected, re-stamped report. We quote it up front.
Upload the report and drawings. We review the inputs and method, and tell you whether it holds up. Corrected stamped reports available.
