I received a part but was not in original box
Some of the parts especially heavy parts like diverter valves and fans are not very well packed, therefore we re-pack them into larger boxes, so we may add protection for the parts. Therefore you may receive for example an alpha diverter in a box marked chaffoteaux.We recycle packaging so you are not charged for any of the packaging material costs - only for the actual courier charges that we pay.
Are your parts used or reconditioned?
No. Our parts are not used or reconditioned. All parts are new. We offer lower prices by buying in bulk direct from manufacturers of the parts.
Can i place an order over the telephone
