A Comprehensive Guide to Replacing Your Furnace – Part 2

We’ve discussed the different signs you should replace your furnace in part one. In this article, we will talk about the factors you should consider when buying a new furnace for your home.

1. Fuel Source  

The fuel source is one of the first factors to consider when choosing a new furnace. In Canada, the most common options are natural gas, propane, oil, and electricity. The fuel source you choose will affect your furnace’s cost and efficiency.

Natural gas is Canada’s most popular fuel source, as it is affordable and efficient. Propane is another option, but it is more expensive than natural gas. Oil furnaces are less common, as they require a storage tank, but they are adequate for homes in remote areas. Electric furnaces are the most expensive to operate, but they are a good option for homes that do not have access to natural gas or propane.

2. Energy Efficiency

The energy efficiency of your furnace is another crucial factor to consider. A more energy-efficient furnace will save you money on energy bills in the long run. In Canada, furnaces are rated by their Annual Fuel Utilization Efficiency (AFUE). The higher the AFUE rating, the more efficient the furnace is.

In Canada, a furnace must have an AFUE rating of at least 90% to be considered high-efficiency. Look for furnaces with an Energy Star certification, as they meet strict energy efficiency guidelines set by the government.

3. Size

The size of your furnace is another critical factor to consider. A furnace that is too small for your home will not be able to keep up with the demand for heat, while a furnace that is too large will waste energy and money.

To determine the correct size furnace for your home, you will need to consider the square footage, insulation, and climate of your home. Consult a qualified HVAC professional to determine the correct size furnace for your home.

4. Features

When choosing a new furnace, it’s essential to consider the features that are important to you. For example, some furnaces come with variable-speed fans, which can help distribute heat evenly throughout your home. A programmable thermostat can also be helpful, allowing you to set the temperature in your home based on your schedule.

Other features include air filtration systems, humidifiers, and zone control systems. Air filtration systems can help improve the air quality in your home, while humidifiers can add moisture to the air during dry winter months. Zone control systems allow you to control the temperature in different areas of your home independently, which can help to reduce energy costs.

5. Cost of Installation and Maintenance

When choosing a new furnace, it’s essential to consider the cost of installation and maintenance. The cost of furnace installation can vary depending on the unit type, the size of your home, and the complexity of the installation. In addition to the cost of furnace installation, you will also need to consider the cost of ongoing maintenance and repairs.

It’s also essential to look for a reliable model with a good warranty. Look for a furnace with a warranty that covers both parts and labor. You should also consider the cost of replacement parts and repairs and the availability of qualified technicians in your area.


Choosing a new furnace for your home requires careful consideration of several factors. The fuel source, energy efficiency, size, features, and cost of furnace installation and maintenance are all essential factors to consider when choosing a new furnace.
