A $500 home warranty typically covers a range of systems and appliances in your home. The specific coverage can vary depending on the warranty provider and the terms of the contract. Generally, it may include items such as plumbing, electrical systems, heating and cooling systems, water heaters, and major appliances like refrigerators, dishwashers, ovens, and washers/dryers. It's important to review the details of the warranty contract to understand the specific coverage and any limitations or exclusions.
