American Residential Warranty typically prefers that customers use their network of licensed and insured service contractors for repair work. This approach allows them to ensure that the contractors meet the necessary standards and provide quality service. However, in some cases, customers may have the option to choose their own contractor, but this could be subject to certain conditions and may require prior approval from American Residential Warranty. It is important for customers to review the specific terms of their home warranty policy, as there may be limitations or requirements regarding external contractors. For the most accurate and detailed information regarding contractor selection, it would be wise to check the current web page or the policy documentation associated with your coverage.
