Furnace size is determined by your home’s square footage, insulation, climate, and other factors. It’s best to consult with a professional technician who can perform a load calculation to determine the right size for your specific needs.
Oversized or undersized furnaces can lead to inefficiencies and comfort issues.

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

There are several heating systems to choose from, including:

• Gas Furnaces: These are efficient and widely used for their affordability and heating capabilities.
• Electric Furnaces: These are suitable for areas with milder winters but tend to be less energy-efficient.
• Heat Pumps: They can both heat and cool your home, providing year-round comfort.
• Hybrid Systems: Combining a heat pump and a gas furnace for maximum efficiency in different weather conditions.
• Ductless Mini-Splits: Ideal for heating individual rooms or spaces without a central duct system.

Furnace filters should be changed every three months. Regularly changing your filter will ensure the air quality inside your home, as well as the safety and comfort of you and your family. In addition, regularly changing the filter will ensure your furnace doesn’t overheat, resulting in damage or an unexpected breakdown.

Preventative maintenance like this extends the longevity of your furnace and helps reduce maintenance and repair fees.

Not sure how long ago your filter was changed or if it needs to be replaced? A heating services provider can take a look at your filter and let you know if it should be replaced with a new one.

If you live in Edmonton or other northern areas your furnace should be professionally serviced once per year. This will prevent you from having to get expensive furnace repairs or replacements and will extend the life of your furnace. In fact, regularly scheduled inspections and service on your heating system can help identify potential breakdowns and reduce emergency repairs by as much as 95%! Regular service can also lower utility bills by up to 30%.

Harsh winters in Edmonton, and other Albertan cities, can take a toll on heating systems. A company that provides furnace service and maintenance will ensure that everything is in top working condition so that you can rely on your furnace all through the winter without having to worry about issues or failures.

Here’s how much furnace tune-ups & servicing costs in Edmonton.

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 professional technician will have an extensive checklist to go through when providing furnace tune-up service and maintenance. The items on this list cover every part of your furnace in order to ensure that it is in top working condition.

Some of the most important items included in this furnace service checklist are:

• Vent, blower, and ductwork cleaning
• Inspection of the flue for damage and dents
• Examination of all belts and their tension
• Adjustment of the furnace’s pilot light flame
• Calibration of the thermostat
• Visual inspection of all electrical wiring
• Inspection of the furnace filter
• Cleaning and removing any debris

A checklist that includes no less than 22 points of inspection should be used during your furnace service.

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.
