Full Furnace and Duct Cleaning Process

If it’s been a couple of years since your last duct cleaning, it’s best to start there. Professional duct cleaners use high-pressure compressed air to blow through your supply runs, then vacuum out dust, debris, and allergens that have accumulated over time.

For many homeowners, the ducts were last cleaned on the day they took possession of the house. Doing a thorough duct cleaning first ensures that any dust or debris trapped in your duct system won’t circulate back into your furnace during maintenance.

After duct cleaning, it’s time for your annual furnace maintenance. Most furnace manufacturers recommend servicing your system once a year to keep it running efficiently and safely. During maintenance, a professional will inspect, clean, and test your furnace according to the manufacturer’s checklist.

By cleaning the ducts first, your furnace starts the season with a fresh filter and no leftover dust, ensuring the system operates at peak performance.

While annual furnace maintenance is a must, duct cleaning depends on your home’s needs. For most Calgary homes, a duct cleaning every 2–4 years is sufficient. Homes with pets, allergies, or heavy dust may require more frequent service.

Remember: always clean ducts before furnace maintenance to maximize the benefits of both services.
