Store & Return Policy

1. Orders and Shipping

Processing. Most orders ship within 3 business days unless the product page says otherwise. Some orders take up to 30 business days.
Carriers. We ship from locations in Massachusetts & New Hampshire with tracking. We also ship direct from distributor warehouses in other locations depending on proximity to the customer. US orders usually ship by USPS Ground Advantage or Priority Mail. International orders ship by FedEx, DHL or international postal service.
Rush orders. We do not offer rush or overnight shipping. Our custom and build-to-order items take time to make carefully, so please plan ahead. Don’t wait until just before a road trip or vacation to order. We can’t speed up an order to meet a personal deadline.
Changes and cancellations. To change or cancel an order, contact us as soon as possible. Once an order has shipped, the return rules below apply.
Our right to cancel. We may cancel any order, for example because of a pricing error or a stock problem. If you have already paid, we refund you in full promptly.

2. Returns

Every return needs a Return Authorization (RMA) number from us before you ship. Please use a carrier that provides tracking.

3. Warranty and Defective Parts

If a part arrives defective or fails because of a defect, we will repair or replace it. We pay shipping both ways within the continental US for approved defective-part claims. To make a claim:
  1. Contact us and describe the problem.
  2. Get an RMA number from us.
  3. Pack the part securely and send it back with your proof of purchase for inspection.
We process warranty claims as quickly as we can.

Compressor Limited Warranty (1 year)

Compressors carry a 1-year limited warranty against manufacturing defects. Defects are rare; most early compressor failures are caused by installation problems. To keep your warranty valid:
  • Replace the receiver drier and the thermal expansion valve when you install the compressor.
  • Keep proof of purchase for both parts, dated within 30 days before or after the compressor purchase. We may ask to see it. Altered or fake receipts are not accepted.
  • Flush the system properly. Internal debris from an unflushed system voids the warranty.
  • Use only R-134a or R-12 refrigerant. Any other refrigerant voids the warranty.
The compressor warranty covers the part only. It does not cover labor, refrigerant or other materials. This warranty is in addition to any rights you have under Massachusetts law.

4. International Orders

Contact us for a shipping quote. We invoice international orders directly and accept major credit cards. We do not ship to every country. We will not misstate value or contents on customs forms.

5. Pre-Orders and Backorders

Pre-orders. Some products are made to order. The terms for each offer are on its product page.
Backorders. If an item you ordered goes on backorder, we will contact you promptly. You can choose a full refund or keep your place in line. To reserve a spot for an item that is already backordered, contact us.

6. Installation and Use

Our kits change the original design of your vehicle’s climate control system. They are not approved, reviewed or endorsed by Mercedes-Benz Group AG (formerly Daimler AG) or by Sanden. Mercedes-Benz and Sanden names are used only to identify compatible vehicles and parts.

Our kits and components should be installed only by a technician certified to service motor vehicle air conditioning systems (for example, under EPA Section 609). Kits are sold for off-road use only. By installing a kit, you accept that it is not a manufacturer-approved modification.

To the fullest extent permitted by law, we are not responsible for damage caused by improper installation, misuse, or the use of non-approved refrigerants.
