We deliver the full package for the City of Orillia Building Department from $695, typically within 3-5 business days.
What your Orillia mechanical package includes
Every Orillia HVAC design package contains a room-by-room CSA F280 heat loss and heat gain calculation at -25°C, equipment selection and sizing (furnace, heat pump, AC, or hydronic), mechanical drawings showing duct or piping layout and the equipment schedule, the MVDS ventilation design (mandatory under OBC 2024), and the Schedule 1 designer declaration. Every page carries our BCIN stamp so the City of Orillia Building Department accepts the submission without a designer-qualification hold.
Sized for Orillia -25°C (Zone 6), not the GTA
Orillia sits at the colder end of Climate Zone 6 with an OBC January 2.5% design temperature of -25°C from Supplementary Standard SB-1 — below Barrie (-24°C), approaching Muskoka (-26°C), and far below Toronto and the GTA at -18°C. Designs copied from GTA assumptions badly undersize equipment here. We size every system to the calculated load at -25°C. If you are considering a heat pump, note a cold-climate unit delivers roughly 55-65% of rated capacity at -25°C, so we verify its output against the load and specify backup heat where appropriate. See the Orillia heat loss page and our cold climate heat pump guide.
