Frequently Asked Questions

Duct cleaning has quite a few benefits, including improved air quality and reduced allergy symptoms. Clean ducts create a cleaner home by removing any buildup of dust, debris, irritants, and allergens. Duct cleaning can even help improve the smell of your home by eliminating substances like mold or mildew.

You should have your ducts serviced at least once every 5 years. Regular duct cleaning clears your ducts of dust and debris that buildup over time. Duct cleaning also removes potentially harmful substances like mold and allergens. A cleaning can even help improve the smell of your home by removing contaminants.

The length of your duct cleaning will vary depending on the size of your home, but they typically take 4 to 6 hours. Of course, larger homes have larger duct systems, increasing how long the duct cleaning will take. If it’s been a while since your last duct cleaning, it could also take longer if there are more dust and debris to remove.

The cost of your duct cleaning will vary depending on your home. The main thing to consider is the size of your home as larger homes have more ducts, which increases the cost. We offer free in-home assessments where one of our Home Comfort Advisors will provide you with a more detailed price estimate based on your home.

You don’t need to be home while we clean your ducts, but it doesn’t hurt. If you’re home, we can alert you immediately if there are any issues. During routine cleanings, we have found mold and even asbestos, and we want you to know about issues like these as soon as possible.
