Why the design temperature matters in Regina
−32.4°C is the 4th-coldest design temperature of the 70 cities we cover. The F280 calculation works out how much heat each room loses on that design day, from the house's actual walls, windows, air leakage and ceiling insulation.
At −32.4°C, even cold-climate heat pumps lose capacity just when you need heat most. The room-by-room number tells you how much the heat pump can cover and how much backup heat to plan for, rather than guessing from square footage.
In the Regina area, 76% of households heat mainly with a forced-air furnace and about 10% with a boiler and radiators; natural gas is the main heating energy for 70% of households and electricity for 19% (Statistics Canada, 2023).
Why skipping it costs money
Contractors who size by square footage routinely oversize. An oversized heat pump costs more to buy, cycles on and off, dehumidifies poorly in summer and wears faster. An undersized one leans on backup heat. The F280 report is the evidence either way, and it's worth having before you compare quotes.
What it costs
About $150–$400 as a standalone calculation (a September 2026 planning range; quotes vary). Many energy advisors bundle it with an EnerGuide evaluation, which also gives the calculation measured air-leakage data instead of an assumption.
NRCan-licensed service organizations serving Regina
Many energy advisors also do room-by-room CSA F280 calculations for an extra fee; HVAC designers do them too. Ask for the F280 report itself, not just an equipment recommendation.

Heat pump programs in Regina
Heat loss calculation in Regina: common questions
What design temperature is used for heat pump sizing in Regina?
NRCan's HOT2000 climate data gives −32.4°C for Regina International. Your designer may use the building code's design value for Regina, which can differ slightly; ask which one the calculation uses.
How much does a heat loss calculation cost?
About $150–$400 standalone as a planning range; often less when bundled with an EnerGuide evaluation.
Who does F280 calculations in Regina?
Many of the 12 NRCan-licensed organizations serving Regina offer them, as do HVAC designers. Ask for the F280 report itself.
Do rebate programs require a heat loss calculation?
Requirements vary by program and change often. Even where it isn't required, it is the best protection against an oversized or undersized system.
