Repair Terms:
• By appointment only: please contact us via email to schedule a drop-off, pickup, or shipment of equipment.
• Our shop rate is $50.00 per hour, with a 2 hour minimum.
• We have a non-refundable $50 diagnostic fee ($75 for equipment shipped to us), due in advance, which gets applied to the repair cost. After diagnosis, we will send you an estimate via email. If the estimate includes more than $50 in parts, we will require an additional advanced payment to cover the price of the parts.
• Most of our estimates are accurate, but occasionally we must increase the price if we find additional repairs are needed. For example: if the equipment will not turn on, the original estimate is for repairing its power problem, and upon repairing the power problem we discover other problems, we will notify you of additional charges.
• Most repairs are completed within 2 weeks. Exceptions to this term are when we need parts that take longer to receive. We will inform you in the estimate the expected completion time.
• All repair charges are due upon the completion of the repair.
• Equipment left with us over 30 days from completion, or not paid for within 30 days, will be considered abandoned and the equipment becomes our property to dispose of as we see fit. An exception to this term would be if the repair is paid upon completion and arrangements are made with us to store the equipment for an agreed upon period.
• We have a 90-day parts and labor warranty on all repair work. The warranty period begins upon the completion of the repair, not when it is picked up.
