Your furnace is the unsung hero that keeps your home warm and comfortable during relentless Alberta winters. A little attention to furnace maintenance can prevent breakdowns, lower energy bills and extend its life.
So, how often should you clean your furnace? What does proper care look like?
Why furnace maintenance matters
Regular furnace maintenance improves efficiency and safety while protecting your investment. A neglected furnace works harder, costs more to run, and is more likely to break down when you need it most.
It’s not just about heat. Maintenance also improves indoor air quality by reducing dust and allergens that circulate through your home.
How often should you clean your furnace?
Most Alberta homeowners should have their furnace cleaned and inspected once a year. The best time is early fall before the heating season begins. An annual cleaning ensures your furnace is ready for winter and gives a technician time to catch small issues before they turn into expensive repairs.

How often should you change your furnace filter?
Changing or cleaning the furnace filter is the easiest and most important maintenance step you can do yourself.
How often? Replace or clean your filter every one to three months.
- Homes with pets or allergies may need monthly changes.
- If you notice dust buildup or reduced airflow, it’s time for a new filter.
Where is it located? Most filters are found near the blower motor, inside or near the return air duct.
What other parts of your furnace need attention?
Check the blower motor
The blower motor pushes warm air through your home. Dust buildup or worn parts can cause it to strain or fail. If you hear unusual noises or notice weak airflow, schedule a professional inspection.
Keep vents and ducts clear
Blocked vents make your furnace work harder. Walk through each room to ensure vents are open and not covered by furniture or rugs. Clean vents with a vacuum and a damp cloth to remove dust.
Inspect the exhaust flue (gas furnaces)
Gas furnaces produce carbon monoxide, which must be vented outside safely. A blocked or damaged flue is a serious hazard. Have it checked once a year by a professional.
Clear the area around your furnace
Furnaces need proper airflow and a safe workspace. Remove clutter, especially flammable materials like cardboard, cleaning products, or paint cans.
How to reduce the heating load on your furnace
The less strain on your furnace, the longer it will last. Improving your home’s efficiency is key.
- Seal drafts around windows and doors.
- Add insulation where needed.
- Close vents in unused rooms to focus heat where you need it most.

Signs your furnace needs attention
Your furnace often gives warning signs before it fails. Watch for these red flags:
- Strange noises such as banging, rattling, or squealing.
- Sudden increases in your energy bill.
- Frequent on-off cycling.
- Uneven heating or cold spots around your home.
If you notice any of these issues, schedule a tune-up or repair as soon as possible.
