Furnace Replacement Costs in Calgary Explained by a Professional

If your furnace is more than 10 to 12 years old, it’s reaching the end of its expected lifespan. Even if it’s still running, older furnaces are less efficient, more prone to breakdowns, and can cost more to repair than replace.

A good first step is to check your furnace’s venting system. This detail alone can significantly impact your replacement cost.

Take a look at your furnace. If you see a plastic vent pipe, that’s great news — it means you already have a high-efficiency furnace. Replacing it is usually a straightforward “like-for-like” swap, keeping your installation costs lower.

You can typically expect to pay between $3,500 and $7,000 for a furnace replacement with plastic venting.

However, if your system has a metal vent pipe, it likely means your furnace is older and less efficient. In that case, the venting system must be updated to meet current standards, which adds complexity and cost. Replacements for these systems usually range from $6,000 to $15,000.

Several factors influence the final price of a furnace installation in Calgary:

• • Type of venting system (plastic vs. metal)

  • Furnace efficiency rating

  • Home size and layout

  • Ductwork modifications

  • Additional comfort upgrades (filtration, humidifiers, or UV lights)

It’s also a good idea to have your hot water tank checked during furnace replacement, as both systems often share venting. Addressing them together can reduce overall labor and future costs.

Replacing your furnace isn’t just about avoiding breakdowns — it’s an opportunity to improve your home comfort and air quality.

If certain rooms in your home are too hot or too cold, your HVAC professional can inspect the duct system and recommend adjustments. You can also explore upgrades like:

• • Smart thermostats for better temperature control

  • Enhanced filtration systems for cleaner indoor air

  • Ultraviolet (UV) lights to remove bacteria, mold, and odors

By taking a proactive approach, you can extend the lifespan of your new furnace and enjoy a more comfortable home year-round.

If your furnace is over 12 years old, it’s wise to schedule a proactive assessment. This helps you understand your options, budget for the replacement, and avoid an emergency situation in the middle of winter.
