If you’re a Calgary homeowner thinking about upgrading your heating system, you’ve probably heard the buzz about heat pumps. With rebates, energy savings, and environmental benefits, they’re being called the “future of home heating.” But how well do they actually perform in Calgary’s unpredictable weather?
This guide breaks down the real pros and cons of heat pumps in Calgary, so you can make an informed choice that fits your home, budget, and comfort needs.

How Heat Pumps Work in Alberta’s Cold Climate
Unlike a furnace that burns fuel, a heat pump transfers heat. In winter, it extracts warmth from the outside air (yes, even in freezing temperatures) and brings it indoors. In summer, it reverses to cool your home.
Thanks to modern cold-climate models, today’s systems can work efficiently down to about –25°C, which is ideal for most Calgary winter days. Advanced inverter technology and improved refrigerants help maintain steady indoor comfort without overworking the system.
However, when temperatures drop below that range, most homeowners use a dual-fuel setup, where the heat pump handles mild days, and a gas furnace automatically takes over during extreme cold.
The Biggest Advantages of Heat Pumps in Calgary
A heat pump replaces both your furnace and air conditioner. That means one system keeps your home warm in winter and cool in summer, perfect for Calgary’s long heating season and short, hot bursts in July.
Many homeowners in neighborhoods like Mahogany and Evanston love the convenience of an all-in-one comfort system, especially for new builds or efficiency-focused renovations.
Lower Energy Bills and Higher Efficiency
Heat pumps are incredibly efficient. For every unit of energy used, they can produce up to three to four times more heat. That’s 300–400% efficiency compared to even the best gas furnaces, which top out around 98%.
On mild days (–5°C to +10°C), a heat pump often costs less to operate than a furnace. Over a full year, that can mean noticeable savings on your utility bills, especially if you also use solar panels or time-of-day power rates.
Reduced Carbon Emissions and Greener Heating
Because they run on electricity instead of natural gas, heat pumps dramatically reduce carbon emissions. For homeowners who want a more eco-friendly home or are planning to electrify over time, it’s a major step toward sustainability.
Rebates and Government Incentives
Heat pumps qualify for rebates under the Canada Greener Homes Initiative, offering up to $5,000 for eligible installations. Some Calgary-area utility companies also offer additional incentives for hybrid or high-efficiency systems.
These programs can help offset upfront costs and shorten the payback period significantly.
The Potential Drawbacks of Heat Pumps in Calgary
With anything, if there are pros, there are also cons. So, let’s go over the things that you need to watch our for with a heat pump.
Higher Upfront Cost
Installing a heat pump in Calgary typically costs between $6,000 and $12,000, depending on your home’s size and whether it’s paired with an existing furnace. That’s higher than a standard furnace installation, which ranges from about $4,900 to $8,000.
The good news? Long-term energy savings and rebate programs can make up for that difference over time.
Slightly Reduced Efficiency in Extreme Cold
Even the best cold-climate heat pumps lose efficiency below –25°C. During those deep-freeze nights, the system may rely more on backup gas heating.
That’s why many Calgary homeowners choose a dual-fuel system, the furnace kicks in automatically when the temperature dips too low for the heat pump to operate efficiently.
May Require Electrical Upgrades in Older Homes
If your home was built before the 1980s or hasn’t had a major electrical upgrade, your panel may need additional capacity to handle the new system. This isn’t a dealbreaker, but it’s something to factor into your budget.
Longer Payback Period Without Rebates
While operating costs are lower, Calgary’s natural gas prices remain relatively affordable. This means heat pump savings grow gradually over time, especially for older homes with less insulation.
Which Performs Better in Calgary?
| Feature | Heat Pump | Gas Furnace |
| Efficiency | 300–400% (heat transfer) | 95–98% (fuel burning) |
| Operating Cost | Lower in mild temps | Cheaper in deep cold |
| Upfront Cost | Higher ($6K–$12K) | Lower ($4.9K–$8K) |
| Heating Range | Works to –25°C | Works below –35°C |
| Cooling Option | Built-in | Requires separate AC |
| Eco Impact | Low carbon | Higher emissions |
The truth is, neither system is perfect for every home. Calgary’s wide temperature swings make a hybrid heat pump + furnace combo the smartest choice. It keeps operating costs low during mild weather and provides reliable gas backup when it’s bitterly cold.
Are Heat Pumps Worth It in Calgary’s Climate?
- Homeowners in well-insulated or newer homes.
- Those planning long-term energy savings.
- Families looking to reduce their carbon footprint.
- Anyone wanting both heating and cooling in one system.
FAQs About Heat Pumps in Calgary
How cold can a heat pump work in Calgary?
