Calgary Furnace Installation, Replacement, Repair & Service

Typical Calgary residential installs run **$5,500-$12,000 all-in**, depending on tier and scope.

Entry single-stage 92% AFUE: $5,500-$7,500. Mid two-stage 95-96% AFUE (most common spec): $7,500-$9,500. Premium modulating 97-98% AFUE: $9,000-$12,000+.

Cost adds: chimney liner $800-$1,500, ductwork mods $500-$3,000, gas line upsize $300-$800. All flagged before install. Our furnace cost in Calgary 2026 guide has the full breakdown.

Depends on your insulation, ductwork, and whether you also need cooling.

A modern high-efficiency furnace is the simplest and lowest-cost-upfront path, especially for older homes with marginal insulation. A hybrid setup (furnace + cold-climate heat pump) cuts your gas bill 60-70% across the year while still using the furnace for the worst cold-snap weeks.

Our heat pump vs furnace in Calgary guide walks through the math with real Calgary numbers. If a hybrid sounds right, we install those — see heat pumps in Calgary.

Consider replacement when your furnace is over 15-20 years old (typical lifespan), repair costs exceed 40% of replacement, the unit fails repeatedly within 24 months, or your heat exchanger has cracked (safety issue — never repair).

Under 15 years old with a single failed component (igniter $250-$450, inducer motor $400-$700, control board $500-$900)? Usually worth the repair.

We give honest replace-or-repair assessments — if your 12-year-old furnace just needs an igniter, we'll do the repair and tell you so.

Annually, ideally booked September through October before the heavy heating season starts. The annual service includes combustion analysis, heat-exchanger crack inspection (safety check that matters most), blower cleaning, filter change, and a full safety system test including carbon monoxide.

Annual maintenance is also required to maintain warranty coverage on most modern furnaces — skip it and you may void parts coverage if you ever need a claim.

We're an AirEase Pro Team dealer and install AirEase most often — the 12-year parts-and-labour warranty is the strongest in the market, and the A96 two-stage and A97 modulating units perform reliably through Alberta winters.

We also install and service Carrier, Lennox, Rheem, Daikin, and most other brands. Avoid the no-name builder-grade units from big-box retailers — the warranties are weak and part availability becomes a problem within 5-7 years.

Straight replacements typically complete in 6-10 hours (one day). More complex jobs requiring ductwork modifications, chimney lining, or gas line upgrades may extend into a second day. Winter installs require freeze-protection precautions and may take longer. We confirm timeline at the quote stage.

Yes. Calgary requires a residential gas permit and inspection for furnace installations, plus an electrical permit when ECM blowers need a dedicated circuit. FlameTech handles all permit applications, schedules inspections, and registers manufacturer warranties as part of the install — no homeowner paperwork chasing.

In nearly every case. Condensing units (90%+ AFUE) extract extra heat from exhaust gases that older 70-80% AFUE units lose up the chimney.

In Calgary's seven-month heating season, the efficiency gain typically saves $300-$600 per year in gas. Payback on the install premium happens in 5-8 years and the furnace runs another 10-15 years after that.

The only cases where standard efficiency might make sense: temporary install (selling within 2-3 years) or a mechanical room where condensate drainage genuinely can't be routed.
