We offer 90-days Part and Labor Limited Warranty. If we fix of refrigeration and it malfunctions again in the next 3 months following the original repair, we will return for free and determine the cause of the problem. If the malfunction has anything to do with the original repair, we will fix it for free. If the machine has the same problem for another reason, we will treat the repair as if we had diagnosed both problems at the same time and will price it accordingly. You pay the same amount had we made the complete diagnosis on the first trip to your house.
