Heat Pumps in Canada's Warmest Corner

More heating days covered

With milder winters, a heat pump can handle a larger share of the heating season before a furnace or backup heat is needed.

Hybrid setups

Pairing a heat pump with a gas furnace is common. The thermostat switches between them based on outdoor temperature.

Summer cooling

The same unit cools all summer, replacing a separate air conditioner.

Defrost

On cold, damp days the outdoor unit may stop to defrost and give off steam. That's normal.

Placement

Raise the outdoor unit above snow and away from roof run-off.

Electrical panel

Older homes may need an electrical upgrade.

Programs

Check current government and utility programs before buying.

Questions to ask

How cold can this model heat at full output? How will it work with my furnace?

How it works

A heat pump moves heat rather than making it. In summer it pulls heat out of the house like central air; in winter a reversing valve sends heat the other way, pulling warmth in from the outdoor air.

Running costs

Savings depend on electricity and gas rates and where the switch-over point is set in a hybrid system. Ask the contractor to explain both.

Noise

Modern outdoor units are fairly quiet, but placement still matters near bedrooms and close property lines.

Upkeep

Change filters regularly, keep the outdoor unit clear of snow and leaves, and book a yearly check of refrigerant and controls.
