Choosing the right SEER level isn’t just about your individual bill; it also fits into Canada’s broader energy and emissions story. The national electricity mix is dominated by hydro, with hydroelectricity accounting for roughly 60% of generation and a large majority of total electricity coming from non‑emitting sources like hydro, nuclear, and renewables, as detailed in the Electricity sector in Canada overview. That means in many provinces, kWh saved through higher SEER primarily reduce costs and free up clean electricity for other uses such as electrified transportation or industry.
However, not all provinces have the same generation mix. Some rely more heavily on fossil‑fuel generation, particularly coal and natural gas. The BDC glossary explicitly notes that seasonal efficiency metrics like SEER and HSPF are especially important in Canada because our climate exposes buildings to both hot summers and cold winters, making efficient systems a long‑term cost and emissions lever for businesses and households alike, as explained in the Business Development Bank of Canada’s energy efficiency ratio glossary.
In simple terms:
Many Canadians are now choosing high‑SEER heat pumps as part of a broader electrification strategy—replacing or backing up fossil‑fuel heating while maintaining efficient cooling. In those cases, it’s often worth going a bit higher on both SEER/SEER2 and HSPF/HSPF2 to future‑proof your energy costs and comfort.
