What Oakville's winter means for your heat pump
In Oakville, the average January low is -7°C, and the coldest temperature recorded from 2015-2024 was -27°C. That's milder than 34% of the 123 cities we track. Choose a cold-climate model, and compare heating output at -20°C, not just at mild temperatures. Keeping some backup heat for rare deep-cold snaps is common and sensible.
