All orders are filled on a first come first serve basis. We strive to process orders within 48 hours, but due to demand we occasionally do find items out of stock. If we are out of stock on an ordered part, Service Pro Parts reserves the right to substitute a part of equal or greater value in it's place when available, otherwise we will ship your items as soon as we receive our stock. All parts carry a one year manufacturers warranty and do not include labor to replace defective parts. Any warranty parts must be returned for inspection and replacement. All parts (with the exception of electrical parts) carry a 30 day money back warranty, returned parts must be in their original packaging and in unused condition. There is a 20% restocking fee on returned parts. There are no returns allowed on electrical parts. Please include a copy of your sales receipt with any returns. Thanks from the sales team at Service Pro Parts.
