Heat Pump vs. Gas Furnace in Calgary
Calgary winters aren’t exactly kind — so choosing the right heating system matters more here than almost anywhere else in Canada.
You’ve probably heard a lot about heat pumps lately. Energy-efficient, government-backed, and popular in warmer provinces — but how do they really perform in a city that routinely hits -30°C?
This guide breaks down the heat pump vs gas furnace debate for Calgary homeowners. We’ll cover efficiency, upfront costs, lifespan, and the real-world performance that determines your comfort — and your bills.
Because in Calgary, “energy efficient” doesn’t mean much if it can’t handle February.
The Super-Short Answer
01
Yes, heat pumps can heat in Calgary.
Most "standard" units stay useful to about –5 °C; cold-climate models keep going well below that.
02
But on today's Alberta rates, natural gas usually wins on cost per unit of heat.
03
Smart play:
run a heat pump for cooling + shoulder seasons, let your gas furnace take over when it's cold. That's called dual-fuel, and it's the Calgary special.
What's a heat pump (in 10 seconds)?
It's an AC that can run in reverse. In summer it moves heat out; in winter it moves heat in. Super efficient in mild weather, a bit less magical as it gets colder (plus defrost cycles to clear outdoor ice).
Calgary Reality Check
Weather:
We live in the land of chinooks and cold snaps.
Power vs gas:
With typical local prices, gas heat is usually cheaper than running a standard heat pump for the same heat output.
Comfort:
Heat pumps shine in fall/spring; gas furnaces are beasts in deep winter.
The two "balance points" (no math degree required)
  • Mechanical balance point: The outdoor temp where your heat pump can't keep up with your home's heat loss. Below that, you need backup heat.
  • Economic balance point: The temp where another heat source (here: gas furnace) becomes cheaper per unit of heat—even if the pump can still run.
  • In Alberta, that "switch to gas" point is often warmer than you think, which is why dual-fuel is king.
So… should you heat with a heat pump?
Choose a Heat Pump (with backup) if:
  • You already want AC (the pump gives you AC + cheap shoulder-season heat in one unit).
  • You're considering solar/TOU rates or care about emissions.
  • You'll get a cold-climate model and you're okay with a furnace or electric backup for deep cold.
Choose a Gas Furnace (primary heat) if:
  • You want the lowest operating cost in Calgary winters—consistently.
  • You want high, steady heat with no defrost pauses when it's bitter out.
  • Your existing ductwork is sized for a furnace and you plan to keep it for years.
Choose Dual-Fuel (our favorite)
You want the best of both:
Heat pump handles
  • cooling
  • mild days
Furnace takes over
near your economic balance point (often around –5 °C to 0 °C for standard units—set it in the thermostat).
Result: comfort, resilience, better bills, fewer compromises.
Quick "Calgary Math" Intuition
Electricity prices × real-world COP (heat pump efficiency as temps fall) ≈ more $/heat than gas most of the winter.
Shoulder season? The COP is high and electricity wins more often—run the heat pump there.
What changes the answer for your home?
  • Your rates: ¢/kWh and $/GJ (and whether you've got solar).
  • Your equipment: Standard vs cold-climate heat pumps; published low-temp capacity matters.
  • Your house: Insulation, airtightness, window quality, square footage.
  • Your goals: Lowest cost vs lower emissions vs needing AC anyway.
Calgary Homeowner Checklist
01
Do you want AC?
→ Heat pump makes tons of sense (you'll use it all summer).
02
Keeping your furnace?
→ Ask for a dual-fuel thermostat with a settable balance point.
03
Going pump-first?
→ Insist on a cold-climate model, good defrost drainage, and clear snow around the outdoor unit.
04
Budgeting?
→ Compare installed cost + operating cost for your usage, not internet averages.
05
Final sizing & setup:
Let a licensed pro confirm load, ductwork, and controls. (DIY guesses = chilly regrets.)
Friendly FAQs
How low can a heat pump go?
Standard units are "happy" to roughly –5 °C. Cold-climate models keep useful output well below that—but you'll still want a backup plan in YYC as the electrical cost to run a heat pump in -30 is much more expensive than a gas furnace!
Will the heat pump replace my furnace?
It can—but most Calgary homes do best with dual-fuel: the pump takes the easy days; the furnace owns the cold snaps. If you have an existing furnace and want to go just heat pump, an air handler is required to replace the furnace.
What about defrost?
In freezing weather, the outdoor unit will periodically defrost. That's normal. Plan drainage so meltwater doesn't refreeze under the unit.
What We Recommend (Fast Paths)
Path A: Dual-Fuel (most popular here)
Heat pump + existing gas furnace, auto-switchover near your balance point.
Comfort + strong operating-cost control.
Path B: Cold-Climate Heat Pump + Backup
Specify low-temp capacity and plan for backup heat on the coldest days.
Great if you want to minimize gas usage and still stay comfy.
