Share This Post

Your furnace and ducts are essential to your home’s heating and cooling system, and keeping them clean is vital for maintaining a comfortable indoor environment. But how often should you clean your furnace and ducts?

Read on to learn the answer to this as experts in HVAC in Pickering shares some information:

How Often Should You Clean Your Furnace and Ducts?

The answer to this depends on things such as the type of furnace you have, the size of your house, how many people are in your household, as well as the amount of pet hair and other debris in your home.

If you have a standard forced-air furnace, it is recommended that you have it inspected and serviced by a qualified technician every year or two. The technician should clean and adjust the burner and blower and check the safety controls.

In addition, you should clean the furnace filter every month. A dirty filter can restrict airflow and result in the furnace overheating, damaging the blower motor.

If you have a high-efficiency furnace, you should have it serviced every two years. These furnaces have sealed combustion chambers and don’t require annual servicing, but they need to be checked periodically to ensure they are operating safely and efficiently.

As for duct cleaning, experts do recommend that you have your ducts professionally cleaned every three to five years. This will help to remove dust, pollen, and other debris that have accumulated over time and may cause allergies or respiratory problems.

Telltale Signs Your Ducts and Furnace Need Cleaning and Maintenance

1. You’ve never had your ducts cleaned.

If you’ve never had your ducts cleaned, it’s definitely time to do so. Over the years, dirt and debris can build up in your ductwork, causing your HVAC system to work even harder to move air through the ducts. This can lead to increased energy costs and reduced efficiency.

2. You can see dust or debris coming from your vents.

If you can see dust or debris coming from your vents, it’s a good sign that your ducts need to be cleaned. This is especially true if the dust particles are visible in the air when your furnace or air conditioner is running.

3. Your furnace filter is dirty.

Your furnace filter should be checked monthly and replaced or cleaned as needed. An unclean furnace filter can obstruct airflow and cause your furnace to work even harder.

4. You have allergies.

If you have allergies, you must keep your ductwork clean. Dust, pollen, and other allergens can build up in your ducts and be circulated through your home each time your furnace or air conditioner runs. This can make your allergies worse.

5. You notice increased dust in your house.

If you’ve noticed an increase in dust inside your home, it could be telling you that your ductwork needs to be cleaned.

6. Your energy bills have increased.

If you’ve noticed a sudden increase in your energy bills, it could be a sign that your HVAC system is working harder than it needs to. Many things, including dirty ductwork, could cause this.


It is a good idea to keep your furnace and ducts clean and well-maintained. This will help to ensure a comfortable indoor environment and improve the efficiency of your heating and cooling system. So make sure you always stay on top of your duct and furnace maintenance.
