We deliver the full package for the Town of Newmarket from $695, typically within 3-5 business days.
What your Newmarket mechanical package includes
Every Newmarket HVAC design package contains a room-by-room CSA F280 heat loss and heat gain calculation at -22°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 Newmarket Building Services accepts the submission without a designer-qualification hold.
Sized for Newmarket -22°C (Zone 6), not the GTA
Newmarket sits in Climate Zone 6 with an OBC January 2.5% design temperature of -22°C from Supplementary Standard SB-1 — about four degrees colder than Toronto and the lakeshore GTA at -18°C. Designs copied from GTA assumptions undersize equipment for the coldest Newmarket days. We size every system to the calculated load at -22°C. If you are considering a heat pump, note a cold-climate unit delivers roughly 65-75% of rated capacity at -22°C, so we verify its output against the load and specify backup heat where appropriate. See the Newmarket heat loss page and our cold climate heat pump guide.

What design temperature do you use for Newmarket?
-22°C, Newmarket OBC January 2.5% value from Supplementary Standard SB-1 (Climate Zone 6). It is colder than the GTA at -18°C, so we size to -22°C rather than GTA assumptions to avoid undersizing.
