Reviews for local air duct cleaning companies can be found on business review sites such as Yelp and Customer Lobby within the users' specified location. Some businesses also feature customer reviews directly on their sites.
Yelp allows its users to write and read reviews of different business locations throughout the world. Reviews are collected in a special business page created for each business within an area. To find a specific business on Yelp, users must first locate the search section of the site and enter a location, such as a ZIP code or city and state, along with either the business name or business type, such as air duct cleaner. Search results show all related businesses within the given location, with options to expand or modify the search area as well as filter results based on factors such as price or overall rating.
Each review on Yelp consists of a satisfaction ranking in the form of one to five stars and a written account of the user's experience with the business. Reviews of local duct cleaners cover topics such as efficiency, cost and overall quality of the cleaning job. Depending on the size of the city, the number of reviews may vary.
