Free Calgary Furnace Size and Price Calculator!

Price is always a key factor when purchasing anything. Here is the breakdown to help you understand the range of pricing on furnaces.

The short version; $3,200 to $6,500 for the equipment, materials, permits, and labor.

Why such a big range?

Furnace efficiency, warranties, brands, equipment add-ons, unit size and install application vary from home to home and then there is the contractor variable to consider.

Ballpark Calculator

Use as a budgeting tool. A proper manual j calculation or heat loss/gain report is the most accurate and professional method for sizing HVAC equipment.

With multiple unit replacements, most contractors will give a discount.

In Calgary and area, square footage is one way to ballpark sizing and another way, multiply the above grade square footage by 35-50 btu.

This will give you the size of unit required. BTU/hr

Homes built AFTER 2005 get a multiplier of 35 btu.

Homes BETWEEN 1982 and 2005 get a multiplier of 42.5 btu. If you’ve performed upgrades to windows and attic, you can lean towards 35 btu.

Homes BEFORE 1982 multiply by 50 btu. If the windows and attic are upgraded, bump to 42.5. If the exterior insulation, windows, and attic have been upgraded, bump to 35 btu.

In all those scenario’s, do not count the basement  square footage.
