Why the design temperature matters in Saguenay
−28.9°C is the 8th-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 −28.9°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 Saguenay area, 64% of households heat mainly with electric baseboards; electricity is the main heating energy for 76% of households (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 Saguenay
In Quebec, EnerGuide evaluations for existing homes run through the provincial Rénoclimat program; the organizations below are the ones NRCan lists for Saguenay postal codes.
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 loss calculation in Saguenay: common questions
What design temperature is used for heat pump sizing in Saguenay?
NRCan's HOT2000 climate data gives −28.9°C for Jonquière. Your designer may use the building code's design value for Saguenay, 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 Saguenay?
Many of the 3 NRCan-licensed organizations serving Saguenay 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.
