Heat Pumps in the GTA
Heat pumps have come a long way — cold-climate models now hold decent efficiency well below zero. But they're not a drop-in replacement for a furnace without some real thought about backup heat, sizing and how the system behaves once temperatures really dive.
Cold-climate models are a different animal
Standard heat pumps lose efficiency fast below freezing. Cold-climate units are built to keep working through a typical GTA January — but sizing still matters.
Backup heat strategy
Most setups here pair a heat pump with a furnace or electric backup for the coldest stretches. We help you figure out what backup makes sense for your home.
Dual-fuel systems
A heat pump paired with a gas furnace switches automatically based on outdoor temperature and cost — common in this region for good reason.
Older ductwork compatibility
Heat pumps often move air differently than a furnace. We check whether your existing ducts support it before recommending a system.
Your Heat Pump Struggles Once It Gets Really Cold
A heat pump losing capacity below zero, running constantly without keeping up, or a backup heat source that never seems to kick in properly — these point to sizing or setup issues, not necessarily a broken unit.
Proper Sizing and Setup for This Climate
We install and service cold-climate heat pumps with backup heat strategies that match how Ontario winters actually behave, so the system performs instead of just running constantly and falling short.

Heat Pump Questions
Do heat pumps actually work in Ontario winters?
Cold-climate models do, especially when paired with backup heat for the coldest stretches. Standard models struggle below freezing.
Do I still need a furnace with a heat pump?
Many GTA homes use a dual-fuel setup — heat pump for most of the season, furnace or electric backup for extreme cold. We can help you decide what fits.
Can a heat pump replace my AC too?
Yes, heat pumps handle both heating and cooling, which is part of why they're gaining ground here.
Why is my heat pump running constantly in winter?
Could be normal behaviour in extreme cold, or a sign of undersizing or a refrigerant issue. We can test to confirm which.
Do you service heat pumps you didn't install?
Yes, we service and repair existing heat pump systems regardless of who installed them.
