Having a home warranty provides peace of mind. It usually comes as a surprise when your heating system stops working, your dryer breaks, or your air conditioner goes out. When your systems and appliances need a repair, it is an urgent matter and you want to make sure you're able to afford the cost of getting them fixed. If you have a plan that covers the item that malfunctions, you'll have it paid for minus the cost of any applicable deductible or service fee.
