Windsor Is the One Ontario City Where Oversizing for Winter Ruins the Summer
At -16°C, Windsor has the mildest design temperature of any major Ontario city — and the hottest, most humid summers. That combination inverts the usual Ontario mistake: equipment picked by heating rules of thumb ends up so oversized for the 8-month cooling-and-shoulder season that it short-cycles, dehumidifies poorly, and costs more to run. Windsor is where a cold-climate heat pump can genuinely carry a house year-round with little or no backup — but only when the CSA F280 heating load and the cooling load are both calculated and the equipment threads the two. That two-sided sizing is exactly what our design documents.
Furnace Sized by Southern-Ontario Habit
An 80,000 BTU/h furnace in a Windsor bungalow with a 34,000 BTU/h design load is standard local practice — and it short-cycles all winter while the matched oversized AC struggles with July humidity.
Wrong in both seasonsHeat Pump Picked Without Both Loads
Windsor heat pumps sized on heating alone end up oversized for cooling — poor dehumidification in Ontario’s most humid summers. Sized on cooling alone, they need unplanned backup in January.
Comfort complaints built inComplete Two-Season BCIN Package
Room-by-room CSA F280 at -16°C plus cooling loads, equipment selected to serve both, duct design with per-room CFM, MVDS and Schedule 1 — stamped for Windsor-Essex submission.
Accepted first submissionExactly What Windsor-Essex Building Departments Expect to See
ADUs and basement units in the core, additions across South Windsor and Riverside, new builds in LaSalle, Lakeshore and Tecumseh, and heat-pump conversions with rebate documentation — one complete package.
Room-by-Room CSA F280 Heat Loss & Gain
Every room calculated separately at Windsor’s -16°C design temperature — walls, windows, ceiling, floor, infiltration.
Equipment Sizing Sheet
Right-sized furnace, heat pump, boiler, or AC matched to the calculated load — not a square-footage guess.
Duct or Hydronic Layout Drawings
Fully dimensioned supply and return layout with airflow for every room per HRAI standards.
MVDS & Ventilation Design
The Mechanical Ventilation Design Summary — mandatory on every Ontario new-home permit since January 1, 2025 — plus HRV/ERV selection.
Schedule 1 & BCIN Stamp on Every Page
Signed designer declaration and BCIN stamp throughout — exactly what your Windsor-Essex building department requires before issuing your permit.
Windsor’s mild design temperature means the heat pump alone covers design day with a small electric strip in reserve — the fully-documented no-furnace design that’s genuinely viable here and almost nowhere else in Ontario.
Serving Windsor, LaSalle, Tecumseh, Lakeshore & Essex County
Windsor-Essex municipalities review to the full OBC 2024 standard: CSA F280 calculation, distribution design, MVDS and Schedule 1. New units — basement apartments and ADUs — need per-unit documentation, same as everywhere in Ontario.
The region’s real opportunity is electrification: at -16°C, right-sized cold-climate heat pumps carry homes year-round. Our two-season design is the document that makes the permit, the rebate application, and the contractor’s install scope all agree.
Only Need the Heat Loss Report?
The full HVAC design package is $695 flat. If your Windsor project only requires the certified CSA F280 heat loss calculation, that’s $395 — see the Windsor heat loss page. Same 48-hour delivery.

The questions Windsor homeowners and builders ask most — answered in plain language.
What’s the difference between this and the $395 heat loss report?
The $395 report is the certified CSA F280 calculation only. The $695 package adds cooling loads, equipment selection sized for both seasons, duct design with per-room CFM, ventilation design with MVDS, and stamped mechanical drawings. Just need the report? →
Can a heat pump really heat a Windsor home with no furnace?
Often, yes — at -16°C design temperature, a right-sized cold-climate heat pump covers design day in most Windsor homes with only a small electric backup. The F280 proves it on paper, which is what the examiner and the rebate program both want. Cold-climate heat pump guide →
Why do cooling loads matter for my permit package?
Because Windsor equipment serves two seasons: sizing on heating alone produces oversized cooling, short-cycling, and poor July dehumidification. Our design calculates both loads so the selected equipment is right year-round.
