Frequently Asked Questions

You should get your ducts cleaned for a variety of reasons, including better home air quality and reduced allergy symptoms. Cleaner ducts mean fewer contaminants that can enter the air in your home. Duct cleaning removes potential irritants and allergens like dust, debris, and even mold to help you breathe easier.

Ideally, your ducts need to be cleaned every 5 years. A thorough duct cleaning every few years removes contaminants that buildup in your ducts over time. Duct cleaning can also help with allergy symptoms and can even remove odours from your home by clearing out smelly substances like mold.

How long your duct cleaning takes will largely depend on the size of your home. Generally speaking, however, duct cleaning usually takes 4 to 6 hours. Larger homes will take closer to 6 hours as they have more expansive duct systems. It could also take longer if it’s been a long time since your last duct cleaning, as there will be more debris to clear.

The cost of duct cleaning varies based on how big your home is, but it usually costs around $600. Larger homes have larger duct systems, meaning they will take more time to clean and ultimately cost more. Call us to book a free in-home assessment if you’d like a more detailed estimate.

You don’t need to be home during your duct cleaning, but there are some benefits. If you’re home, we can tell you right away about any issues we come across. Potential issues include things like mold and even asbestos, and we always want to let the homeowner know sooner rather than later.
