❄️ What Does a Heat Pump Do in Winter?

In simple terms, a heat pump extracts heat from outside air—even if it feels cold—and brings it inside to warm your home.

Yes, even in Toronto winters.

This works thanks to a refrigerant system and a special compressor that amplifies small amounts of outdoor heat.

💡 Fun fact: Even at -18°C, there’s still heat energy in the air!


🔄 The Science Behind It

Here’s how it works, step-by-step:

  1. The outdoor unit absorbs heat from the cold air using refrigerant.
  2. The refrigerant is compressed, making it hot.
  3. Heat is transferred into your home through an indoor coil.
  4. A blower fan circulates warm air through your vents or indoor heads (ductless).

🧊 But What If It’s Too Cold?

New models like cold climate air-source heat pumps (ccASHPs) are built for Canadian winters. They operate efficiently down to -25°C.

If you’re concerned about extreme cold, you can:

  • Pair your heat pump with an electric backup heater
  • Use a dual fuel system with your existing gas furnace
  • Install a ductless mini-split for specific areas like basements

  • You’re switching from oil or electric baseboard heating
  • You get access to government rebates (up to $6,500)
  • You use your heat pump for both heating and cooling

Lower energy bills + cleaner energy = win-win.
