How Much Does a New Furnace Cost in Calgary? (2026)
What a high-efficiency furnace runs installed, and when repair still makes more sense than replacement.
A new high-efficiency furnace in Calgary typically runs a few thousand dollars installed, with the final number driven by the size of the unit, its efficiency rating, and how much the venting and gas connection need to change. The honest first question, though, is whether you need a new one at all.
Repair or replace
A ten-year-old furnace with a failed igniter or a bad blower motor is usually worth repairing. A twenty-year-old unit with a cracked heat exchanger is not, because the exchanger is the expensive part and a crack is a safety issue. Age, the specific fault, and how the rest of the unit is holding up decide it.
What drives the install price
- The size and efficiency of the furnace you choose.
- Whether the venting and gas line can be reused or need changes.
- Any code upgrades triggered by the swap.
