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.

Yes! If you’re a ProComfort Dual or ProHeating Member, you can upgrade your plan with our Air Filter Delivery Add-On—designed to make clean air easy and automatic.

Here’s how it works:

• You choose your filter size (we offer a variety to match your system)

• We deliver a full case of filters right to your door

• You set the delivery schedule based on your home’s needs—every few months, seasonally, or just once a year

Whether you’re dealing with allergies, pets, or just want to keep your system running efficiently, this add-on takes the guesswork out of remembering when to replace your filter. It’s one less thing on your list—and one more way we keep your home comfortable, year-round.

In the Edmonton area, you should typically change your furnace filter every 1 to 3 months—but it depends on your home and lifestyle:

• Every 1 month if you have multiple pets, allergies, or live in a dusty area

• Every 2 months for average homes with one pet or light allergies

• Every 3 months in smaller homes with no pets and minimal dust

• More often during heavy-use seasons, like winter (heating) and summer (if you use central AC)

Filter size and quality also play a role—smaller or lower-MERV filters usually need changing more frequently.

If you’re tired of remembering when to replace them, our ProComfort Dual and ProHeating Memberships offer an Air Filter Delivery Add-On. We’ll deliver the right filters to your door on schedule—so your home stays clean, your air stays fresh, and your HVAC system runs at its best without any guesswork.

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.

In Alberta, a heat-loss calculation must be done when installing a new furnace. When hiring a professional to do your install, this will be factored into the price.

Hiring a professional heating company to install your furnace is essential. It may cost more initially but will save you money, time, and headache in the long run.

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.

The difference between a boiler and a hot water tank has to do with the way in which each uses the hot water that it produces.

Both boilers and hot water tanks take cool water, heat this water and then distribute it throughout a home via pipes. However, the water that is heated by a boiler is distributed throughout the home via pipes, radiators and radiant in-floor systems in order to heat it – to keep the rooms, floors, garage, etc. comfortable and warm.

On the other hand, a hot water tank heats water that is used for cooking and cleaning purposes – for showers, dishwashing, laundry, etc.

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.
