Furnace Installation FAQs

In Calgary, a new high-efficiency furnace typically costs between $4,000 and $8,000, including installation.

While all new furnaces are “high-efficiency”, units with multi-stage heating and advanced blower control have improved efficiency and quieter operation.

The following are typical price ranges, including installation:

Single-stage furnace, fixed-speed blower: $4,000 to $5,500
Two-stage furnace, variable-speed blower: $5,000 to $6,900
Modulating furnace, variable-speed blower: $6,200 to $8,000

Furnace pricing depends on the model you choose, but also on home size and installation requirements. To find out, get a custom quote.

Yes. Furnaces more than 10 years old are only 60 to 80% fuel-efficient and their reliability gets worse over time (especially without regular maintenance).

All new furnaces are high-efficiency — 96% fuel-efficient or better — and we offer models rated up to 99% fuel-efficient. If you replace an old furnace, the heating cost savings can be substantial.

Yes. Older furnaces typically exhaust through a rooftop flue which acts as a common exhaust for your furnace and hot water tank. New high-efficiency furnaces usually exhaust through an outside wall, close to the ground.

During the quoting process, our installation experts will review the specifics of your home, the proximity to your neighbours, and determine if building code will permit your new furnace to exhaust through an outside wall or an existing roof flue.

Depending on the age of your old furnace and the dimensions the new unit, some modifications may be required.

Two of the most common modifications are:

  1. Plenum adapter or replacement supply and return air plenums — New furnaces are more compact than older units, so a plenum adapter is often needed to connect the furnace to the ducts that draw in cold air and push out hot air to your home. In some cases, the plenum itself may need to be replaced.
  2. Upgraded air filtration rack — The existing filtration rack (where the furnace filter goes) may need replacement due to wear or an improper fit. If you want to add an upgraded air filtration system, it’s best to do it as part of your new furnace install.

During the quoting process, we’ll inspect your existing furnace and ductwork and include the required modifications in your quote.

The following are signs that your furnace needs replacement or repair:

  • Furnace runs but little or no heat comes out
  • Pilot-light fails and needs to be re-lit often
  • Delayed furnace ignition or start-up
  • Bad odours emitted from furnace
  • Sudden rise in heating costs​
  • Frequent or costly repairs

If your older furnace is causing problems, we can provide quotes for both repair and installation to help you decide on the best option.

If your furnace is as old as your home and requires a major repair, the heating and repair cost savings can often make a new high-efficiency furnace a better long-term financial decision.
