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.

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

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.

There are several steps involved in installing your new furnace. These steps will vary depending on the furnace you choose, your home’s existing furnace system, and any changes you want.

1. Align the new furnace with existing gas lines and ductwork
2. Connect and seal to the ducting system
3. Connect intake and exhaust pipes
4. Connect the gas line
5. Connect the furnace to the electrical supply and thermostat
6. Connect the furnace to a drain hole

At this point, it’s important to check your work, make sure everything is connected properly and there are no gas leaks. 

Please note: these steps are extremely simplified and meant to provide an overview to understand the professional furnace installation process better. It is highly recommended that you have your furnace professionally installed in order to avoid dangerous problems and issues with your new furnace. Having to get furnace repairs on your new unit would not be covered under warranty without professional installation.

Hiring a professional will be more costly initially but will save you money in the long run.

Here’s how long it takes to install a new furnace.

Furnace filter replacement is important if you’re using your AC. Maybe not as frequently as in winter when monthly changes are best. But check the filter regularly to see that it is functioning properly, and replace when necessary.

If you run your AC during the spring or fall, you will want to check your filter more often since this time of year has more allergens and particulates in the air that can cause you to become sick.

If there is a crack in the heat exchanger of your heating system, your furnace could be leaking carbon monoxide (CO). This can be dangerous for you and your family, as CO can cause serious bodily harm and even result in death. Carbon monoxide is a colourless, tasteless, and odourless gas and therefore is not easily detected, especially in small quantities.

Your furnace may be leaking carbon monoxide if you or other members of your household are experiencing any of the following symptoms:

• Headache
• Weakness
• Dizziness
• Nausea or vomiting
• Feeling hungover
• Shortness of breath
• Confusion
• Blurred vision
• Loss of consciousness

If you think your furnace is leaking carbon monoxide contact a local heating company right away. If you think you are experiencing carbon monoxide poisoning, please seek professional medical advice immediately.

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.
