The cost of furnace replacement varies depending on factors like the type of furnace, its size, labour costs, and any additional accessories or modifications needed for installation.
On average, you can expect to invest between $5,500 to $10,000+ for a new furnace, including installation. High-efficiency models or complex installations may push the cost higher.

Furnace on the fritz? Here are a few things to check if your furnace isn’t working:

• Power switch – is the power on? If so, try turning the furnace off and then on again.
• Furnace filter – check to see if the filter is clogged. If it is, exchange it for a new one. You should be changing your furnace filter ever 3 months.
• Batteries in the thermostat – check the batteries in your thermostat and replace them if they’re low.
• Flame sensor – turn off the power to your furnace (this is an important first step) then remove the sensor and clean it.
• Pilot light – check to make sure the pilot light is on. If it’s out, relight it using your furnace model’s igniting instructions.
• Air intake and exhaust pipes – check the exhaust flue for blockages and clear any blockage you find. For example, during the winter in Alberta, you might find icicles covering the screen of the flue. Remove these to solve the problem.

If one of these is not the issue, you may need a professional to help you uncover and solve the problem. Don’t wait until it’s too late – a broken furnace, especially during an Edmonton winter, can result in broken and burst water pipes! Find a local furnace repair contractor to fix the problem as soon as possible.

Yes—you definitely should! Even though your furnace isn’t heating your home during the summer, your HVAC system still uses the same ductwork and blower when you run your central air conditioner. That means your furnace filter is still working hard to trap dust, pollen, pet hair, and smoke particles—especially during Edmonton’s dry, dusty summers or wildfire season.

In fact, summer can be one of the most important times to stay on top of filter changes if:

• You use central AC

• You have allergies

• You experience poor outdoor air quality (like wildfire smoke)

• You have pets that shed

Not sure when to change it? Our Air Filter Delivery Add-On (available with ProComfort or ProHeating Memberships) makes it easy. We deliver the right filter size on your preferred schedule—so your home stays cool and your air stays clean, no matter the season.

The key to knowing when to replace your furnace versus when to repair it depends on its age and how many more years you can expect it to last. But, rather than humming and hawing about these questions, there is a simple equation you can use to help you decide.

This equation compares the cost of repairing the unit to the cost of replacing it. Here’s the calculation you can use to decide when you should replace your furnace:

“Cost of Repair” x “Age of Unit (in years)” > “Cost to Replace Furnace” = Replace Furnace

Multiply the cost of the furnace repair by the age of the unit. If this number is less than the cost of replacing your gas furnace, then opt for the repairs. If this number is larger, it will be cheaper to replace the furnace.

If you’re living in Alberta, in the St. Albert/Edmonton area, and you’re still unsure, talk to a local heating company. With their expert knowledge about your particular climate, they will be able to help you make a decision as to whether you should repair or replace your furnace.

A gas furnace is the most efficient way to heat your home and by far the most popular in Alberta. Gas furnaces are reliable, cost-effective, and efficient and manufacturers are continually improving their efficiency and quietness and introducing new features.

Amana is one of the best brands of furnaces, especially for homes in Alberta. Amana is one of the few furnace brands with a stainless steel heat exchanger and the only with a lifetime replacement warranty. This makes an Amana furnace a reliable option for any household.

We also think that Trane Furnaces are an exceptional option in Alberta. They have been very reliable over the past few years and look to continue that manufacturing trend.

If you’re wondering what is the best brand of furnace for your home, talk to a local heating services provider. Their expertise can help you make the best choice for your climate.

The size of the furnace you’ll need largely depends on the size of your home. Size recommendations based on square footage are:

1,200 square foot home: 36,000 to 72,000 BTUs
1,500 square foot home: 45,000 to 90,000 BTUs
1,800 square foot home: 54,000 to 108,000 BTUs
2,100 square foot home: 63,000 to 126,000 BTUs
2,400 square foot home: 72,000 to 144,000 BTUs

Other factors that affect the size of the new furnace installation you’ll need include:

• Climate zone (for example, Edmonton is in Climate Zone 5)
• Quality of insulation
• Window thickness
• Ceiling height
• Number of people living in your home
• Preferred temperature
• Size and state of the basement

You should consider replacing your furnace if it’s over 15-20 years old, requires frequent and costly repairs, produces uneven heating, or if your energy bills have been steadily increasing.

It’s also a good idea to upgrade to a more efficient model to save on long-term energy costs.
