The National Air Duct Cleaners Association recommends getting your air ducts cleaned every three to five years. Ed Mack, owner of Air Duct Professionals in Lake Elsinore, California, says homeowners should consider doing it every two to five years, depending on their circumstances.
Moreover, the majority of duct and vent cleaning services charge by the hour, so it is a good idea to call around and find out about different companies' hourly rates in addition to requesting an estimate for the total cost of the services.n general, it should not take more than 3 to 5 hours for the cleaners to get the job done. During this time, they will use a series of tools to clean out all the ducts and vents within your home or place of business. By having this type of work done, you can notice an immediate improvement in your home's air quality.
