A Complete Furnace Buying Guide + The Best Furnace Brands in Canada

One of the biggest contributors to comfort in your home is the temperature inside. Whether too hot or too cold, if the ambient temperature is outside of that comfortable range, inside will not feel like home. Sweaters can only do so much. In Canada, with winter on the back of everybody’s minds year-round, making sure you have a furnace that is works right is important.  

There are so many HVAC companies that sell furnaces, and among them, so many different models and sizes that it may be overwhelming to shop for a new furnace if the old one starts rattling. Instead of trying to pick individual furnaces, we decided to check out each brand available, figuring out what people like about each brand, their strengths, and their weaknesses, so you can call the right HVAC company that carries the right brand of furnace for you.  

Looking for a new thermostat to pair with your new furnace? We also got you covered here. 


The ins and outs of your furnace

The basic premise of how a furnace works involves a heating component heating the air, and a blower component moving that hot air into the house and moving cold air out of the house.

For gas furnaces, it starts with the fuel source, whether that is natural gas or propane, which ignites in the burner, and heats a metal component simply called the heat exchanger. Similarly, electric furnaces work similarly, with electricity powering heating elements which warm the heat exchanger.

Then, the heat exchanger warms up air in the system, where the furnace blower then moves the heated hair into the ducts which distributes the heat around your home. While warm air is being distributed, cold air is drawn into the return ducts which bring that air back to the heat exchanger.

One last important part of your furnace system, and perhaps the one that you might be most familiar with yourself, is your furnace filter. The filter stops the furnace system from sucking up the household detritus like hair and dust, which can damage your furnace and reduce the air quality in your home. Your furnace filters are the component of the furnace that needs most replacing, as once clogged your furnace will need to work harder to move hot air around your home.

Your furnace is not a complex system, but it is extensive since it runs throughout your home, and one you need to depend on when the winter gets colder.

What to look for in a furnace

Controls: Furnaces have primarily been controlled by thermostat, but some modern furnaces are compatible with smart thermostats, which can be controlled or monitored remotely by smartphone or tablet, programmed to change temperature throughout the day, and send reports or system diagnostics as needed.   

Efficiency:  Efficiency for furnaces is measured in AFUE, which is a percentage of the heat generated out of the amount of fuel used.  Other factors involved in the efficiency of a furnace include the type of furnace, since two-stage and modulating furnaces allow for more control and using less fuel when you need to, instead of the “all-or-none” functionality of a single stage furnace. Efficiency is a big factor as it not only reduces the amount of natural gas you will burn through, making your home more environmentally friendly, but also can save you money in the long run.  

Initial Price: Balancing the efficiency and features of your furnace against its initial cost is an important step. Since furnaces can cost thousands of dollars, you may be tempted into going down the cheaper route, but paying more for a more efficient, technological furnace may pay off in the long run.  

Size: One of the biggest factors that will determine how well a specific furnace will work in your home is how well it is “sized,” in relation to the size of your home. Having a furnace unit that has a heating output that exceeds or does not meet the requirement of your home can cause problems and reduce the lifespan of your furnace. If undersized, your furnace will struggle to heat your entire home, and could push the furnace too far. Likewise, a furnace that is too powerful for your home might wear out from all the starting up and shutting down.  

Warranty: Furnaces are designed to have a long lifespan, around 15 years or potentially longer. Considering the warranty of a furnace might be a good idea, since if anything goes wrong, repairs might be expensive if otherwise uncovered by a warranty. Many furnaces will primarily include proprietary components, meaning that you cannot find 3rd party components to replace it if it breaks or wears down. Repairs can be highly expensive because of this, so opting for a unit with a strong warranty is a great idea.  

Our methodology

When shopping for a furnace, you are also likely shopping for a HVAC company to help with the process. While said company will help you throughout the process, knowing what you are looking for and having some background with different furnaces will be helpful, so you know what you are looking for.  

In our research, we researched some of the most popular furnaces in Canada, and looked into the product lines of each, looking at what people might look for in a furnace, things people might look for when shopping for a furnace includes consistent and quiet performance, energy efficiency, and comprehensive warranty. Other features, including built-in control panels and smart functionality, are nice features that some people may be willing to spend more on but are not necessary. The most important thing by far is getting a furnace with an appropriate size, rated to provide the required amount of BTU’s your home needs.

Frequently asked questions

 What are the furnace types? 

Furnaces range in how they heat the home in their fuel source and the range of settings they provide.  

Energy sources for your furnace fall into 4 different types. Natural gas is one of the most common sources and are highly efficient today. Propane is another common energy source. Oil furnaces are less efficient, but can be cheaper outright, but these furnaces are becoming outdated. Electric furnaces can be costlier, as it will add to your electric bill, but electric furnaces can be cheaper to buy and install and last longer too. This resource is a great place to learn about Canada’s more prominent heating options, and the pros and cons of natural gas and electricity specifically.  

On top of that, many furnaces are separated by how they ignite the fuel source. The following explains the different terms that explain how a furnace works.  

Single stage – The furnace has two modes: off, and full blast. This is the simplest type of furnace and is cheap but inefficient. 

Two stage – The furnace features a high flame setting and a medium setting, for more control.  

Modulating furnace – Instead of one or two settings, modulating furnaces have a spectrum of flame that they can produce, allowing you to finely adjust the amount of heat the furnace produces. These units can be the most expensive upfront but can be the most energy efficient.  

What furnace size do I need? 

Ultimately, getting an appropriately sized furnace is one of the most important factors in terms of how well a furnace will work for you. An undersized furnace will struggle to produce the amount of heat you require, burning a lot of fuel and burning out the furnace in the process. Inversely, an oversized heater will overheat your house, and might be strained as turning a furnace on or off again and again.  

While you can easily calculate an estimate based on the square footage of your home and the climate that you live in, this estimate should not be used for the final decision about your furnace. The furnace you will need will roughly produce between 30-60 BTU (British Thermal Units) per square foot of space, with the range of BTU based on the climate of the area you live, but other factors like insulation or how much vertical space you have will also play a factor.  

What is a high-efficiency furnace? 

Some of the cheaper furnaces are single stage have two options: full power, or off. These furnaces are ultimately inefficient, as the full power setting can burn a lot of fuel. High efficiency furnaces either have the ability to adjust the amount of heat generated or have a more energy efficient way of transferring fuel to heat. Almost all furnaces today will have an efficiency above 80% AFUE, but if you want a high-efficiency furnace, look for furnaces with an efficiency above 90-95% AFUE.  

How is furnace energy efficiency measured? 

Furnace efficiency is measured in a unit called AFUE, which stands for Annual Fuel Utilization Efficiency. AFUE measures the number of units of fuel are converted to heating output.  

How long do furnaces last?  

Typically, a furnace can last you 15 years plus, although this can vary depending on the type of fuel the furnace uses. After 15 years, it is recommended you start looking into replacing these furnaces. There are warning signs you can look for that will tell you when you need to start looking for a new furnace.    

Some of these signs include noises include rattling, popping, humming, screeching, clicking and booming. Other signs include temperature fluctuations and excess dust or soot around furnace registers and the house in general. 

Should I replace or repair my old furnace?  

It depends on a few factors, primarily the age and condition of your furnace. If your furnace is approaching that 15-year age, and has any of the above symptoms, it may be time to replace your furnace. Additionally, if the problem is reoccurring, or the repairs are costly, it may be worth considering replacing the furnace instead.  

What’s the average furnace price in Canada?  

You can realistically expect to pay between $2500 and $6000 on a furnace, while the lower range will most likely include less technology and a lower efficiency.  

Is a professional furnace installation worth it?  

In Canada, a properly certified technician is required by law to install, alter, or replace a furnace. Professionals will have the expertise and certification to install the furnace correctly, which is important when working with something that can be as potentially dangerous as a gas leak can be. Going with a professional also means that you will have professional guidance and support through the process, which can be beneficial when picking a furnace that will suit your living space perfectly.  

What’s a furnace ignitor? 

The furnace ignitor is a key component to furnaces, which ignites the gas or fuel source that powers the heater, which heats the air.  

What’s a good furnace warranty coverage? 

Most furnaces will have some type of warranty, with different lengths of coverage, and different things that the coverage can cover. Many warranties will be limited, meaning they last for the length of the warranty for the original, registered homeowner only. The most common components covered by warranty include the heat exchanger, and other parts inside, however some warranties will cover the full unit if a defect prevents it from working properly. The length of warranties varies, from as little as 1-year, to up to 20-years with some models, but a 10-year warranty is a good length and last most of the expected lifespan of a furnace.  

How often to change a furnace filter?  

How often you need to change a furnace filter is dependant on the type or thickness of furnace filters that are in use. The timeframe that a filter will last for before it needs replacing is indicated in the product information that is included. Otherwise, filter thickness, filter efficiency (measured in MERV), and other factors like amount of family members (including those who walk on 4 legs) might impact how often you might need to change a furnace. The following is a guideline of when you need to start thinking of changing your furnace filter: 

1-2 inch – every 3 months max. 

3-4 inch – every 9 months max. 

5-6 inch – every 12 months max. 

How to clean furnace ducts? 

To clean furnace ducts, you will likely need a vacuum that is stronger than what you can get from your standard household vacuum, and a long reach. Additionally, you will need a brush or something to remove dust that could build-up inside the furnace ducts.  

Remove the screws from your air duct covers, and place paper towels on the inside of the supply vent covers (which blows air out from the furnace) and place the covers back on, so dust does not spew from out of them. Set the fan on via your thermostat, and then loosen any dust in the ducts using a tool like a brush, knocking off any deposits of dusts that might be stuck inside.   

Then, you can start to vacuum the interior of the supply registers, removing the dust that has inevitably built-up. You can then use a damp microfibre cloth or other type of cloth to wipe the interior clean. Then, you can do this with the return registers too. Finally, shut off the fan and furnace, before removing the panels of the furnace, where you can replace the furnace filter and vacuum any extra dust that has built up in the blower compartment.

When should I turn off my furnace?

Many appliances need to be turned off when not in use. While you will certainly get more mileage out of your furnace during the autumn and winter months, during the summer months you might not need your furnace as much. But should you turn off your furnace during the summer months?

The answer is no, but don’t be afraid to turn it down instead.

See, furnaces will only turn on when needed, so only when your thermostat determines the temperature in your house dips below its threshold will the thermostat turn on. Since this process is automatic, there is not going to be too many instances where your furnace will be burning money, even during summer months.

Should I turn off my furnace in spring?

Turning off your furnace may seem like an easy way to save money when the weather gets warmer, but it is not necessarily the best move for you to make.

If you are considering shutting off your furnace at some point during the year, you need to consider if any of your utilities are connected to your furnace. Some water heaters and AC unit are connected to your furnace, and so turning off your furnace come springtime might mean sacrificing comfort or the effectiveness of the appliances in your home.

If your furnace assists with either of these two functions in your home, you should probably not turn off your furnace during the warmer months.

The energy-saving advantages of a furnace inspection

Furnace inspection lets you get the most out of your furnace, so if it’s been a while since your last inspection, here are a few reasons why you should book a furnace inspection.

1. A well-maintained furnace is a furnace with maximized efficiency. Even simple acts like changing out old filters can help you use less energy and save more money.

2. A furnace inspection can identify potential malfunctions or issues and repair them before they become problems down the road.

3. Elongate the lifespan of the furnace by completing necessary maintenance and cleaning.

4. Ensure safe and clean air quality in your home.

5. Some companies might have conditions assuring that you maintained your furnace to maintain the warranty of the furnace. It is better to be safe than sorry.
