Only A Licensed Refrigerator Repair Service Provider is Worth Hiring How good the refrigerator repair service is can be determined by their license. The best service providers for refrigerator repair usually hold a license from the Construction Contractors Board. Having said that, you must always ask the company to provide you with a photocopy of their company’s license before you commit to them. While the primary role of a license is to indicate that the company is legally operating, it can also be safe from the shady work performed by the unlicensed and unauthorized technicians, owing to how the license demands the technicians to prove their experience in the field and track their record.
