First American Home Warranty typically does not cover pre-existing conditions. A pre-existing condition is generally defined as any issue that existed before the start of the home warranty coverage, whether or not it was known to the homeowner. It can include problems that may have been apparent or latent. The purpose of a home warranty is to protect homeowners against unexpected breakdowns of covered systems and appliances, and the inclusion of pre-existing conditions would undermine that purpose. It is important for homeowners to thoroughly review the terms and conditions of their specific policy to understand what is and is not covered. For detailed information, it is advisable to refer to the current web page or documentation provided by First American Home Warranty.
