| Estimated Cost | $5,500 - $7,500 | $6,500 - $9,000 | $8,700 - $11,000 |
These prices reflect current Calgary market trends and include installation. Additional costs, such as permits or optional upgrades like smart thermostats, can further influence the final price.
Types of High-Efficiency Furnaces with Prices
High-efficiency furnaces are an essential upgrade for Calgary homeowners looking to reduce energy costs and enhance home comfort. These systems are evaluated using the Annual Fuel Utilization Efficiency (AFUE) rating, which measures how effectively a furnace converts fuel into heat. For example, a furnace with a 96% AFUE rating turns 96% of its fuel into usable warmth, wasting just 4%.
In Calgary’s cold climate, the minimum AFUE rating for new high-efficiency furnaces is 96%, with advanced models achieving up to 99%. This improvement can result in savings of up to 50% compared to older, inefficient furnaces, making them a cost-effective choice for long-term use.
While single-stage furnaces are more affordable upfront, two-stage and modulating options provide better long-term savings on energy bills and offer quieter operation. Comfort Union’s best-selling furnace is a Two-Stage Variable Speed blower style. We highly promote and recommend that due to cost savings while paying a smaller amount upfront.

What is AFUE and Why Does It Matter?
Annual Fuel Utilization Efficiency (AFUE) measures the percentage of fuel converted into usable heat. For example, a 96% AFUE furnace converts 96% of its fuel into heat, wasting only 4%. The higher the AFUE, the greater the energy efficiency. Learn more about AFUE standards at Natural Resources Canada.
Why Choose a High-Efficiency Furnace?
Energy Savings: High-efficiency models significantly reduce gas and electricity usage, cutting heating costs by up to 40%, as highlighted by the Government of Alberta's Energy Efficiency Programs.
Environmentally Friendly: Lower emissions align with Alberta's eco-friendly initiatives.
Enhanced Comfort: Features like variable-speed motors and smart thermostats ensure consistent temperatures
Furnace Warranty
A furnace is a significant investment, and choosing one with a strong warranty ensures long-term peace of mind. Leading brands like Lennox, Carrier, and Trane offer comprehensive warranties that protect you from unexpected repair costs while ensuring your system operates efficiently for years to come. Here’s a comparison of popular furnace brands and their warranty offerings:

Be sure to register your furnace soon after installation to activate the full warranty benefits.
Furnace Size and Capacity
Furnace size directly impacts the cost and efficiency of your heating system. Measured in BTUs (British Thermal Units), it determines how much heat your furnace can produce to warm your home effectively. Selecting the correct furnace size is essential for maintaining efficiency and avoiding unnecessary costs.

| Estimated Price Range | $5,500 - $6,500 | $6,500 - $7,500 | $7,500 - $9,000 | $9,000 - $11,000 |
Why Does Furnace Size Matter?
Efficiency
An undersized furnace will struggle to heat your home, running constantly and increasing energy bills. Conversely, an oversized furnace can cause short cycling, leading to uneven heating and increased wear and tear.
Comfort
Properly sized furnaces ensure even heating across all rooms, improving overall comfort.
Lifespan
Correct sizing reduces strain on your furnace, extending its operational life and lowering maintenance costs.
How to Determine the Right Furnace Size
Furnace size depends on several factors, including your home’s square footage, insulation quality, and climate zone. For example, a 1,500 sq. ft. home typically requires a furnace with 60,000-80,000 BTUs, while a larger home of 2,500 sq. ft. or more may need 100,000-135,000 BTUs. In Calgary, where winters are severe, proper insulation and a professional heat-loss calculation are critical for determining the right furnace size. This ensures efficient heating and prevents unnecessary energy costs, as highlighted by Natural Resources Canada.
Good Rule of Thumb for Calgary:
40 BTU/sq.ft. ~ Houses built before 1990s
30 BTU/sq.ft. ~ Houses built in 2000s
20 BTU/sq.ft. ~ Houses built in 2020s
