Warranty service times vary throughout the year, and are processed in a first come, first serve manner, when parts are available and in stock. Most repairs/replacements are done within 1-2 weeks, however if there is a long line during the busy season, or if your parts need to be ordered from our manufacturer, processing times can be up to 6-8 weeks. We appreciate your patience and understand everyone has a critical need for their unit, and do everything we can to ensure that these requests are handled as quickly as possible.

We allow a 30 day period (from the date of receipt of the item in the mail) to report such issues–any items missing after that time frame will need to be purchased, and any defective items will be treated as warranty issues for repair or replacement only (no returns for refund). For missing items and broken items, we do require a picture of the shipping label on the box, and of the items that arrived with your unit for verification before we can send any missing items or replacements to you.
