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.

Boiler heat is not expensive on a day-to-day basis. In fact, you may save in energy costs when heating your house with a boiler compared to a furnace.

However, installing a boiler is typically more complex and therefore more expensive than installing a furnace. On average, a boiler will cost anywhere from $2,500 to $10,000 to purchase and install (depending on the brand and the system’s energy efficiency rating). Plus, your home will need extensive modifications to make a boiler system work – radiant heating must be implemented.

On the other hand, the average cost to buy and install a furnace in Edmonton is only $5,500 to $10,000+. With boiler heat, you will save in the long run but will have to pay more upfront.

Heat pumps do not work in Alberta.

While heat pumps are designed to heat efficiently and cool homes by drawing heat from the outside air during cold months and expelling hot air from inside during warmer months, their effectiveness varies based on the climate.

In milder climates, heat pumps can be an excellent alternative to traditional furnaces and air conditioners. Some homeowners even prefer them for their dual functionality. However, in colder regions like Alberta, especially places like Edmonton, the efficiency of heat pumps diminishes.

The reason? As temperatures drop, heat pumps struggle to extract enough warmth from the frigid air to heat a home adequately. In contrast, traditional furnaces are specifically designed to provide consistent and reliable heat, even in the harshest of winters. For Alberta homeowners, where winters can be particularly brutal, relying solely on a heat pump can be a gamble.

Therefore, while heat pumps might be a viable option in some parts of the world, in Alberta, a traditional furnace remains the trusted and recommended choice for ensuring warmth and comfort throughout the year. There are also other and more reliable heating and cooling solutions available to Alberta homeowners.

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.

Boilers can last a really long time. In fact, the average lifespan of a boiler is 10 to 15 years. In order to extend the life of your boiler, it’s important to ensure that it is properly maintained and serviced on a regular basis. Even the best boiler will require maintenance and repairs from time to time.

If your boiler is giving you signs that it needs attention, make sure to hire a professional heating company to do the job. This will ensure your boiler lasts as long as possible. Some signs to keep an eye out for include: low water pressure, no heat coming from your radiators, banging noises, a pilot light that keeps going out or isn’t blue.

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.

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.

Need a new heating system and wondering whether it’s better to rent or buy a furnace? Renting a furnace is definitely cheaper initially but is not the right option for every household.

If you rent a furnace, you will pay a monthly fee and the HVAC dealer will be responsible for maintenance and repairs. However, there are some drawbacks. It is likely that over time you will pay at least double what the furnace is worth. And, because you do not own the heating system, it does not add to the value of your home.

If you can afford to buy a new furnace this is the best option. By buying the furnace outright, you won’t pay any interest and may also be able to benefit from manufacturer or government rebates. Owning the furnace will also add to the value of your home.
