Furnace Replacement: Picking the Best Option for Energy Efficiency and Savings

furnace replacement

Your furnace is essential for maintaining a comfortable and cozy environment in your home, especially during the chilly winter months. However, as your furnace ages, its performance can decrease, leading to inefficient heating, higher energy costs, and potential breakdowns. When it’s time for a furnace replacement, selecting the right unit is crucial to achieving long-term energy efficiency and savings. 

Continue reading as Air Force Heating guides you through the process of choosing the most suitable furnace replacement that ensures comfort, eco-friendliness, and cost-effectiveness in your home. Our professionals are here to help you make the best decision for your specific needs by providing expert guidance and recommendations based on your home’s unique requirements.

1. Understanding Furnace Efficiency Ratings: AFUE Explained

When it comes to furnace efficiency, the Annual Fuel Utilization Efficiency (AFUE) rating is the key metric you need to be aware of. This rating measures the percentage of fuel consumed by the furnace that gets converted into usable heat for your home. A higher AFUE rating indicates a more efficient furnace.

Furnaces with an AFUE rating of 90% or higher are considered high-efficiency, meaning at least 90% of the fuel they consume is converted into heat. While high-efficiency furnaces tend to have a higher upfront cost, they can save you a significant amount on your energy bills over time. When choosing the right furnace replacement for your home, it is essential to weigh the long-term savings of a high-efficiency furnace against the initial investment.

2. Fuel Types: Weighing Your Options

The fuel type of your furnace is another essential factor to consider when selecting a replacement unit. Different fuels have varying levels of efficiency, availability, and cost. Here are the three primary fuel types available for furnaces:

Natural Gas: Natural gas furnaces are the most common fuel source in Canada, and they tend to be the most affordable and efficient option. Operating at efficiencies of 80% to over 98%, these furnaces are an excellent choice for homeowners looking for long-term savings and comfort.

Propane: If natural gas is not readily available in your area, propane is another option to consider. Propane furnaces generally have similar efficiency levels to natural gas models, but the cost of propane can be higher, depending on your location and the size of your home.

Electric: Electric furnaces boast nearly 100% efficiency, as they do not lose heat through venting like gas and propane models. However, they can be less cost-effective due to higher electricity prices compared to gas or propane.

It’s vital to weigh the pros and cons of each fuel type and consult our technicians regarding the best choice for your specific situation and preferences.

3. Sizing Matters: Ensuring a Perfect Fit for Your Home

Choosing the right size for your furnace replacement is critical to maintaining consistent comfort and energy efficiency in your home. A furnace that is too small may struggle to keep your home warm and need to work harder, consuming more energy and reducing its lifespan. Conversely, an oversized furnace may cycle on and off too frequently, causing temperature fluctuations and wasting energy.

To determine the correct furnace size, our technicians will consider various factors, including your home’s square footage, insulation, window efficiency, and local climate. By assessing these elements, we can ensure the optimal furnace size is installed, effectively maximizing comfort and minimizing energy consumption in your home.

4. Compatibility and Customization: Integrating with Your Home’s Existing Infrastructure

The ideal furnace replacement should be compatible with your home’s existing ductwork and ventilation systems, ensuring a seamless integration with minimal disruption. Our technicians will assess your current heating infrastructure and recommend models that can be tailored to suit your home’s unique requirements.

In addition to compatibility, consider add-ons and advanced features that can further improve your home’s energy efficiency and comfort. Consider options like dual-stage heating, variable-speed blower motors, and advanced thermostats that can help fine-tune your home’s heating system for peak performance.


Investing in the right furnace replacement can maximize energy efficiency, generate long-term savings, and ensure consistent comfort in your home. By taking into account factors like efficiency rating, fuel type, size, and compatibility, along with the guidance of our expert technicians, you can make an informed decision that will benefit your home for years to come.
