Cold Climate Heat Pumps That Perform in -25°C

Worried your heat pump can’t handle Canadian winters? Cold climate heat pumps, like the high-performance KingHome models, are designed to operate in extreme temperatures down to -25°C while providing dependable heating in winter and cooling in summer. 

If you're wondering, “Do heat pumps work in cold climates like Ontario?” or “Is a cold climate heat pump worth the investment?” — the answer is yes. These systems are engineered to deliver consistent comfort and lower energy bills all year long.

What Makes Cold Climate Heat Pumps Different? 

Unlike standard heat pumps, these units use inverter-driven compressors and cold-weather refrigerant systems to adapt in real time, maintaining warm indoor temperatures even as the outdoor temperature drops. 

Key performance features: 

  • Works efficiently in -25°C conditions 
  • Up to 20 SEER2 and 10+ HSPF2 ratings 
  • Dual heating and cooling in one compact unit 
  • Uses eco-friendly R-410A refrigerant 
  • Low-profile outdoor design for flexible installation 
  • Whisper-quiet operation indoors and outdoors 

From freezing winters to humid summers, these systems adjust seamlessly to Ontario’s changing climate. 

Choosing the Right Heat Pump Starts with the Right Info

Should I Turn Off My Heat Pump in Extreme Cold? 

No — cold climate heat pumps are built to keep running efficiently even during deep freezes. If temperatures ever fall below operating range, the system may switch to a backup or emergency heat source. But under most Ontario conditions, your heat pump stays in control.

Is This Right for Your Home? 

Cold climate heat pumps are perfect for: 

  • Primary residences and cottages in Ontario 
  • Older homes switching off oil or baseboard systems 
  • New builds looking for energy-efficient solutions 
  • Homes with limited mechanical space 
  • Families applying for energy rebates 

Their smart modulation uses only the energy required — saving you money while avoiding the “cold air” blasts common with older systems.

Maintenance Tips For Your Kinghome Cold Climate Heat Pump

To keep your cold climate heat pump performing at its best: 

  • Replace or clean filters every 1–3 months 
  • Clear snow and debris from around the outdoor unit 
  • Schedule seasonal tune-ups to check refrigerant, coils, and defrost cycle 
  • Don’t shut it off in cold weather — let it run continuously for stable indoor temps

Frequently Asked questions

Will my heat pump still work when it’s -20°C outside?

Yes. These models are tested and rated to perform efficiently at -25°C.

Do I need a furnace as backup?

Not always. Many homes run purely on heat pumps, but a hybrid setup (with gas furnace) can add flexibility and extra peace of mind.

Why is my heat pump blowing cold air?

This can happen during a defrost cycle. It’s normal and temporary. If it continues, a service call may be needed.

Does emergency heat cost more to run?

Yes — electric emergency heat is typically more expensive. But it only activates when temperatures are extremely low or if there’s a malfunction.

Can I install the outdoor unit anywhere?

Avoid shaded, snow-prone, or low-clearance areas. Our team will help choose a location that ensures optimal airflow and protection.

What rebates are available in Ontario?

Many cold climate heat pumps qualify for federal and provincial energy incentives. We’ll help you apply.
