How Much Does a New Furnace Cost in Calgary (2025 Update)
Spoiler: It's not as simple as "five grand." But we'll get you close — minus the sales pitch.
Why Furnace Pricing Feels Like a Mystery
You'd think buying a furnace would be easy. Walk into a store, check a tag, pay, done. Except — furnaces don't work like that.
In Calgary, the cost of a new furnace depends on a dozen moving parts: your home size, efficiency rating, the installer, the venting setup, and even whether your old one was installed before YouTube tutorials existed.
But you came here for numbers — so let's talk real Calgary pricing, what's included, and how to avoid overpaying for your next upgrade.
The Real-World Price Range (2025 Calgary Averages)

Mid-efficiency furnaces are no longer permitted for new installs in Alberta. As of 2010, all replacements must meet high-efficiency (condensing) standards. So if a quote includes "mid-eff," that's your cue to back away slowly.
What's Actually Included in a Proper Quote
A proper furnace quote should include everything from start to finish — not just the shiny box.
Equipment
Brand, BTU size, and model clearly listed.
Labour
Safe removal, setup, venting, wiring, and testing.
Venting upgrade
Two new PVC pipes (intake + exhaust).
Gas + electrical permits
Required by Alberta code.
Thermostat
Basic or smart thermostat install.
Warranty
10-year parts + 1–2-year labour (minimum).
If your quote just says "Furnace install – $4,999," ask for a breakdown. You're buying peace of mind, not mystery math.
What Affects the Price
No two homes — or installs — are quite the same. Here's what drives cost:
1. Furnace Size (BTU Rating)
Most Calgary homes need 60,000–100,000 BTU, depending on square footage, insulation, and layout.
A pro should perform a heat load calculation (Manual J) before quoting. Guessing size "by feel" is old-school — and expensive long term.
2. Home Layout & Access
Basement stairs, tight clearances, or long vent runs can add $300–$700 in labour. Finished basements sometimes mean extra time or drywall repair.
3. Electrical & Gas Line Upgrades
Older systems may need a new gas shutoff or circuit breaker. Expect $200–$600 if required to meet code.
More Factors That Impact Your Final Cost
4. Zoning Systems for Large Homes
If your home has hot upstairs / cold downstairs syndrome, zoning can fix it.
Zoning systems use motorized dampers and multiple thermostats (one per floor) to balance comfort and efficiency.
Expect an additional $1,200–$2,500, depending on layout and zone count — but you'll never fight over the thermostat again.
5. Brand & Warranty
Top-tier brands (Lennox, Trane, Carrier) cost more but include stronger warranties, quieter motors, and smart diagnostics.
6. Add-ons
  • Smart thermostat: +$400–$800
  • Humidifier or HRV: +$900–$1,600
  • AC coil prep: +$900
  • Surge protector: +$250–$500
The Installation Process
Here's how a proper Calgary install usually goes down:
01
Prep & safety
Power + gas shutoff, floor protection.
02
Remove old unit
Disconnect venting, wiring, sheet metal and drain.
03
Set new furnace
Align, level, connect gas, sheet metal and electrical.
04
Run new PVC venting
Sidewall or roof terminations.
05
Connect condensate line
Drain to floor or pump.
06
Install thermostat & test
Check airflow, ignition, and safeties.
07
Final inspection
Submit permits and verify operation.
Simple swaps: 6–8 hours.
Full retrofits or zoning systems: 1-2 full days.
Comparing Furnace Quotes (Without Losing Your Sanity)
1. Line-by-Line Transparency
Each quote should clearly show:
  • Brand + model
  • BTU and efficiency rating
  • Warranty terms
  • Labour and materials
  • Optional add-ons
If any of that's missing — ask for it. Clarity saves thousands.
2. Licensed & Insured
Your installer must:
  • Hold an Alberta Gas Fitter A/B license
  • Be WCB-insured and bonded
  • Pull proper City of Calgary permits
3. Reputation Check
Google reviews, Better Business Bureau, and HVACHelp.pro's trusted list are your best friends.
4. Rebates & Financing
Ask about:
  • 0% interest financing (common fall/winter promo)
  • Manufacturer rebates (especially for high-efficiency models)
  • Energy Efficiency Alberta or Enbridge programs (when active)
5. Avoid "Furnace Rentals"
If it says "$0 down, lifetime warranty" — read the fine print. Many are long-term rental contracts with liens on your home.
Always ask: "Do I own the furnace once payments are done?"
Calgary-Specific Considerations & When to Replace
Elevation & cold climate
Calgary's thin air means furnaces run harder; higher BTU sizing and dual-stage operation are recommended.
Venting
Always ensure 24 inches above grade clearance to prevent ice-ups.
Filter access
Ask your installer to orient the filter for easy homeowner changes.
When Replacement Makes Sense
Replace your furnace if:
  • It's 15–20 years old
  • It has visible rust or cracks
  • Repairs are $1,000+ within a season
  • You notice uneven heating or loud startups
A new system will boost comfort, safety, and resale value while slashing gas bills.
Bottom Line
Buying outright or financing beats renting every time.
You'll pay less, own the equipment, and keep your home lien-free.
