What your Midland mechanical package includes
Every Midland HVAC design package contains a room-by-room CSA F280 heat loss and heat gain calculation at -24°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 Town of Midland Building Department accepts the submission without a designer-qualification hold.
Sized for Midland -24°C (Zone 6), not the GTA
Midland sits in Climate Zone 6 with an OBC January 2.5% design temperature of -24°C from Supplementary Standard SB-1 — among the colder Zone 6 areas, on par with inland Barrie (-24°C) and well below Toronto and the GTA at -18°C. Penetanguishene and Tiny Township share -24°C. Designs copied from GTA assumptions badly undersize equipment here. We size every system to the calculated load at -24°C. If you are considering a heat pump, note a cold-climate unit delivers roughly 55-70% of rated capacity at -24°C, so we verify its output against the load and specify backup heat where appropriate. See the Midland heat loss page and our cold climate heat pump guide.
