Replacement parts for air conditioners are sold through home improvement and hardware stores such as The Home Depot, specialty parts retailers such as Repair Clinic and through mass retail websites such as Amazon. Internet auction sites such as eBay also feature many listings for replacement air conditioner parts.
The Home Depot's website allows users to view all air conditioner replacement parts available online and in stores. Each part's listing contains a picture of the unit as well as a detailed manufacturer description of its function and the units with which it is compatible. Listings also feature user ratings and reviews, though users are not required to purchase the item in order to write a review. The site allows users to check the inventory of local stores to see if a particular part is in stock. If a store does carry that part, then the user is able to have the part reserved for an in-store pickup rather than have it shipped to them.
One useful feature of the Amazon website is the question and answer section it provides on all product listings. In this section, users are able to ask specific questions about a product before buying it, with answers provided by the Amazon community.
