Your furnace burns gas. Your AC only cools. A heat pump does both—and costs less to run year-round. Here's the real comparison.
If you're choosing between these three systems for your BC home:
Best choice for BC: Heat pump. It does everything a furnace does (and more), costs less to operate, and qualifies for massive rebates.
An air conditioner takes heat from inside your home and moves it outdoors. That's it. It only works in summer. When winter comes, you need separate heating (usually a furnace). So you're paying for two systems to do one job.
A furnace burns natural gas to create heat, then pushes warm air through your home. In summer, you need an air conditioner for cooling. In winter, you flip to the furnace. Two systems. Two fuel sources.
The problem: Gas prices in BC have doubled in the last 5 years. Your furnace gets more expensive to operate every year.
A heat pump is clever. It's like an air conditioner running in reverse.
In summer: It moves heat from inside to outside (AC mode). In winter: It moves heat from outside to inside (heating mode). Even at -20°C, heat energy exists in the air. The heat pump extracts it, compresses it, and delivers it as warmth.
Result: One system does both heating and cooling. One fuel source (electricity). One thermostat to control everything.

What is COP and AFUE? COP (Coefficient of Performance) for heat pumps measures how much heat you get per unit of electricity input. A COP of 3 means you get 3 units of heat for every 1 unit of electricity. AFUE (Annual Fuel Utilization Efficiency) for furnaces measures how much heat from burning gas actually goes into your home (85–95% is typical; 5–15% escapes through the chimney).
BC homeowners sometimes worry: "What if it gets extremely cold?" The answer: Use a hybrid system.
A hybrid setup pairs a heat pump with a backup furnace (or electric coil):
Why hybrid? Because heat pump installation costs are lower than installing a furnace. You keep the old furnace as backup (you can remove it later). Net result: You get heating + cooling for less upfront cost, and you still get the rebate.
Real BC data: Kelowna's record low is -37°C (once every 20 years). Vancouver's is -15°C (rare). Prince George's is -58°C (record, 1968). Modern heat pumps are rated to work at -30°C with 80%+ efficiency. Most BC homes never need the furnace backup. Hybrid systems are optional insurance, not required.
False. Modern cold-climate heat pumps (Mitsubishi Hyper-Heat, Fujitsu XLTH, Daikin Fit) are engineered for exactly this. They use advanced refrigerants and inverter compressors that work efficiently even at -25°C.
Real testing: Manufacturers test these units to -30°C in labs and in Canada's cold regions (Alberta, Northern BC). They all pass. COP (efficiency) stays high.
Modern heat pumps are quieter than furnaces. No combustion noise. Just a gentle hum.
Wrong. An 8 kW heat pump costs $8,000–$12,000 installed. About the same as a furnace replacement. But it also cools your home, so you skip the AC system.
Replace your furnace or AC system. Here's the true cost:
Payback math: You save $300–$1,600/year on heating + cooling. Payback is 4–6 years (or 2–3 years if income-qualified). After 10 years, you've saved $3,000–$16,000.

See your city's heat pump rebate →Yes. You can install a heat pump and keep your furnace as backup. This is the hybrid approach. Over time, you can remove the furnace and rely 100% on the heat pump. The rebate still applies.
Install a heat pump. Faster than waiting for a furnace. Same price range. Better long-term economics. You'll get the rebate immediately.
Yes, in most cases. If your home already has ducting (from a furnace or AC), the heat pump can use it. Installation is simpler and faster. Ask your installer about your specific setup.
Ductless systems are great for individual rooms or additions. But for whole-home heating, a ducted heat pump is more efficient and easier to control. Both get rebates.
No. Even though heat pumps use electricity (not gas), they're so efficient (COP 3–4) that your total bill goes down. You save $300–$1,600/year compared to a furnace + AC setup.
Less than furnaces. No annual inspections, no cleaning the flue. Just basic filter changes 1–2 times/year. Cost: ~$100/year.
Heat pumps are proven technology. Tens of thousands installed in Canada. Lifespan: 15–20 years (same as furnaces). Warranty: 5–10 years parts, 10-year workmanship from installer.
