Size a heat pump for a Canadian home in minutes — and get the numbers rebate and permit applications ask for. Enter a postal code and the basics of the house. Heat Pump Sizing Canada resolves the design temperature from NRCan weather data, calculates the design heat loss and heat gain with CSA F280-12 methodology, and shows the heat pump size that fits: capacity at the design temperature, balance point, and how much backup heat the home needs on the coldest day. HOMEOWNERS get a plain-language estimate to take to a contractor. CONTRACTORS get Pro Mode — measured R-values, wall area, NFRC window ratings, HRV/ERV recovery — and a branded PDF with a Heat Pump Sizing Summary for rebate and permit documentation. HEAT PUMP SIZING Enter a specific unit's rated heating capacity at 47 °F and 17 °F from its AHRI or NEEP listing and the app evaluates that unit: balance point, capacity at your design temperature, backup heat required. BUILT FOR CANADIAN HVAC PROS Metric by default — m², kW, RSI, °C — with a full imperial toggle throughout the app and PDF exports. THREE LEVELS OF ACCURACY Simple Mode – 7 inputs: Regional climate benchmarks from your Canadian postal code and floor-area factors. Get an estimate in under 60 seconds with zero measurements. Perfect for quick quotes and initial sales conversations. Moderate Mode — 16 inputs: Component-level factors — insulation grade, windows by orientation, foundation, blower-door ACH50, CSA F326 ventilation — with a conservative safety buffer. Prevents undersizing while staying accessible for non-engineers. The sweet spot for standard replacement jobs. Pro Mode – your measured values: assembly R-values (RSI), actual above-grade wall area, basement wall depth and below-grade insulation, NFRC window U-factor and SHGC, and HRV/ERV heat recovery. Every input feeds the CSA F280 calculation directly. Free – no upgrade. BUILT FOR CANADA Enter your postal code — we resolve province, city, and design conditions from NRCan HOT2000 weather data mapped to your Forward Sortation Area (FSA). Coverage from mild coastal BC to Arctic climates. WORKS IN THE FIELD Offline-first — no signal in the basement? Everything runs locally. Auto-save projects. LiDAR room scan (iPhone and iPad Pro) fills floor area, ceiling height, windows and wall perimeter from a walk-through. Professional PDF reports — the document you hand to a homeowner, an inspector, or a rebate application. Tagged site photos with location labels and notes in report appendices. Optimized for iPad. THE MATH YOU TRUST Calculations follow CSA F280-12 residential space heating and cooling load methodology: – Heating load (kW or BTU/hr) – Cooling load — sensible and latent (kW or BTU/hr) – Recommended AC or heat-pump size – real catalog sizes inside the F280 sizing window – Heat pump balance point, capacity at the design temperature and backup heat – Recommended furnace or heating appliance size (5,000 BTU / kW increments) – CSA F326 continuous ventilation and HRV/ERV recovery – Below-grade and foundation heat loss – Equipment sizing guidance for AC, furnace, and heat pump options – Full component breakdown – walls, ceiling, windows, doors, foundation, infiltration, ventilation, latent – that adds up to the headline load Follows CSA F280-12 methodology — the standard referenced across Canadian residential HVAC practice. Not affiliated with or certified by CSA or HRAI. PERFECT FOR HVAC contractors, installers, and service techs across Canada. Heat pump and dual-fuel system installers. HRV/ERV installers sizing ventilation loads. Sales teams quoting new systems. Independent contractors building their business. Energy advisors and high-performance builders. Contractors preparing load documentation for provincial heat-pump rebate programs and permit applications. Homeowners comparing heat pump quotes. No account. No setup.
