Gas Furnace Guide – Improve Comfort and Save Energy

Winters in Calgary and Edmonton can be intense, with cold temperatures requiring a reliable and efficient heating system to maintain your home’s comfort. At Legacy Heating & Cooling, we provide high-quality heating and cooling services, including furnace installation, to homeowners and businesses. One of the most energy-efficient and cost-effective solutions for heating your home is a high-efficiency gas furnace. In this educational and informative article, we will explore the benefits of high-efficiency gas furnaces, how they improve your home’s comfort level, and save energy. Additionally, we will discuss the factors to consider when choosing the right high-efficiency gas furnace for your home, ensuring a tailored solution that best suits your unique needs.

High-efficiency gas furnaces have come a long way in recent years, with many modern models reaching Annual Fuel Utilization Efficiency (AFUE) ratings of 90% or higher. These furnaces use advanced technologies such as variable-speed blowers, modulating burners, and smart thermostats to optimize their performance and minimize energy consumption. By investing in a high-efficiency gas furnace, you not only benefit from improved comfort during the cold months but also experience significant energy savings, reduced environmental impact, and long-term durability.

Trust the experts at Legacy Heating for professional guidance, installation, and maintenance of your high-efficiency gas furnace. Our skilled and experienced technicians will help you select the perfect furnace for your home’s specific requirements, ensuring optimal performance, comfort, and efficiency. Count on us for ongoing support throughout the lifespan of your gas furnace as we continually strive to provide top-quality services and solutions for your home heating needs.

The Advantages of High-Efficiency Gas Furnaces: Comfort, Savings, and Sustainability

High-efficiency gas furnaces offer numerous benefits that make them an ideal choice for heating your home. Some of these advantages include:

1. Improved Comfort: Advanced technologies like variable-speed blowers and modulating burners ensure consistent and precise temperature control, eliminating cold spots and providing even heating throughout your home.

2. Energy Savings: High-efficiency gas furnaces with AFUE ratings of 90% or higher can significantly reduce your energy consumption, lowering your utility bills and providing long-term cost savings.

3. Environmental Benefits: By reducing fuel consumption, high-efficiency gas furnaces help minimize greenhouse gas emissions and contribute to a more sustainable future.

4. Enhanced Durability: Modern high-efficiency gas furnaces are built using high-quality materials and components, providing long-lasting performance and reliability.

Determining the Right Size: Importance of Professional Load Calculation

When choosing a high-efficiency gas furnace for your home, determining the correct size is crucial for optimal performance and energy efficiency. An undersized furnace may struggle to keep your home warm during extremely cold weather, while an oversized furnace can lead to short cycling and increased wear and tear. To avoid these issues, it’s essential to consult with a professional HVAC technician to perform a load calculation for your home.

Load calculations take into account factors such as your home’s size, insulation levels, window sizes and types, and other specific details that impact its heating requirements. With this information, our expert technicians at Legacy Heating can help you select the perfect high-efficiency furnace tailored to your home’s unique needs.

Comparing Efficiency Ratings: Understanding AFUE

The Annual Fuel Utilization Efficiency (AFUE) rating represents a crucial factor in selecting a high-efficiency gas furnace. AFUE is a measure of how efficiently a furnace can convert fuel into heat over the course of a year, expressed as a percentage. For example, a furnace with a 95% AFUE rating means that 95% of the fuel consumed is effectively converted into heat, while the remaining 5% is lost through the exhaust process.

When comparing gas furnaces, look for models with higher AFUE ratings, as these models are more energy-efficient and can provide greater long-term savings. Keep in mind that the minimum efficiency for furnaces varies by region in Canada, with most provinces requiring a minimum of 90% AFUE for new installations.

Additional Features to Consider: Enhancing Performance and Comfort

Modern high-efficiency gas furnaces offer a range of additional features that contribute to improved performance, comfort, and convenience. Here are some noteworthy features to keep an eye out for:

1. Variable-Speed Blowers: These blowers adjust their speed based on your home’s heating needs, providing consistent comfort, quieter operation, and enhanced energy efficiency.

2. Modulating Burners: Rather than simply turning on and off, modulating burners can adjust their heat output in small increments, maintaining a steady temperature and improving overall efficiency.

3. Smart Thermostats: Many high-efficiency furnaces are compatible with smart thermostats that enable advanced controls and energy management. These advanced thermostats can help you program your furnace’s operation, optimize energy consumption, and even remotely control your home’s temperature.


Investing in a high-efficiency gas furnace for your home offers numerous benefits, including enhanced comfort, energy savings, reduced environmental impact, and long-lasting durability. Consulting with professionals at Legacy Heating and Cooling ensures that you choose the right furnace size based on an accurate load calculation, maximizing your home’s heating efficiency and comfort.

Understanding AFUE ratings and considering additional furnace features can help you make an informed decision tailored to your unique requirements.
